Storage jar assembly for a prosthetic heart valve

Description

FIELD

The present disclosure relates to a storage jar assembly that is configured to receive a prosthetic heart valve.

BACKGROUND

The human heart can suffer from various valvular diseases. These valvular diseases can result in significant malfunctioning of the heart and ultimately require repair of the native valve or replacement of the native valve with an artificial valve. Transcatheter prosthetic heart valves are designed with an expandable frame and a valvular structure (e.g., one or more prosthetic leaflets) attached to the frame. This configuration allows the prosthetic heart valve to be inserted in a patient while compressed or partially compressed, and then to be expanded to fit the diameter of the native heart valve being replaced.

In some cases, the prosthetic leaflets, typically made of pericardial tissues, require hydration when they are stored prior to use. The prosthetic heart valve must also be protected from physical damage during shipping and storage. This is generally accomplished by the use of a valve storage jar assembly containing a hydrating fluid, such as glutaraldehyde, allowing the storage jar assembly to both physically protect and hydrate the leaflets of the prosthetic heart valve before it is installed in a patient.

Typically, a prosthetic heart valve is placed loose in a jar and therefore can be exposed to potential damage during storage, shipping and handling through contact between the prosthetic heart valve and the inner surfaces of the jar. Additionally, during device preparation, removal of the prosthetic heart valve from the jar can be awkward or difficult to accomplish because the clinician must reach into the jar with a sterile tool, such as forceps or tweezers, while avoiding contact the sides of the jar and avoiding pinching or tearing of the soft components of the prosthetic heart valve.

Known storage jar assemblies have included a valve holding mechanism for holding a prosthetic valve within a jar. The valve holding mechanism requires the placement of sutures for securing the prosthetic valve to the valve holding mechanism during the assembly process. As can be appreciated, this increases the complexity and length of the assembly process. Moreover, special tools may be required to remove the valve holding mechanism and the prosthetic valve from the jar as well as to remove the prosthetic valve from the valve holding mechanism.

Another issue concerning storage jar assemblies is that prosthetic heart valves come in various sizes. A storage jar assembly designed for a prosthetic heart valve of one specific size may not be suitable for use with a similar valve of a different size.

Therefore, there is a need for storage jars assemblies for prosthetic heart valves that overcome one or more disadvantages of the prior art.

DETAILED DESCRIPTION

Disclosed herein are storage jar assemblies comprising securing mechanisms for prosthetic heart valves. Storage jar assemblies disclosed herein generally comprise a jar and a removable lid. The jar is configured to receive a prosthetic heart valve. The prosthetic heart valve rests within the jar when it is being stored and is removed from the jar prior to use. In particular embodiments, the securing mechanisms can hold a prosthetic heart valve in at least a partially-compressed state to permit use of a relatively smaller jar and/or to better secure the prosthetic heart valve within the jar during shipping and storage.

The storage jar assemblies disclosed herein may be used with various embodiments of prosthetic heart valves. Prosthetic heart valves for use with the presently disclosed storage jar assemblies can have a frame assembly comprising at least one radially compressible and expandable frame and a valvular structure supported within the frame assembly. Additionally, the prosthetic heart valves may have a plurality of anchoring structures for securing the prosthetic heart valve to native tissue of a patient. In some embodiments, the frame assembly can comprise an inner frame and an outer frame.

For example, FIGS. 1 and 2 depict one embodiment of a prosthetic heart valve 10 that can be used with the storage jar assemblies disclosed herein. The prosthetic heart valve 10 comprises a frame assembly 12 and a valvular structure 14 supported by the frame assembly 12. The frame assembly 12 defines an inlet end 22 and an outlet end 20 of the prosthetic heart valve 10. As best shown in FIG. 2, the frame assembly 12 in the illustrated embodiment includes an inner frame 15 and an outer frame 16. The inner and outer frames 15, 16 can comprises a plurality of interconnected struts 18 arranged in a lattice or diamond pattern.

The inner frame 15 can include an annular inner frame body 24. The inner frame body 24 can have a generally cylindrical shape such that it has a substantially constant diameter from an upper end (inlet end) to a lower end (outlet end) of the inner frame body 24. However, it is to be understood that in alternative embodiments, the diameter of the inner frame body 24 can vary along its length. Although inner frame body 24 is described as generally having a cylindrical shape, it is understood that all or a portion of the inner frame body 24 can have a non-circular cross-section such as, but not limited to, a D-shape.

The outer frame 16 can include an annular outer frame body 26 and an outer frame anchoring feature 28. The outer frame body 26 can have an upper region 30, an intermediate region 32, and a lower region 34. In some situations, such as those in which the prosthetic heart valve 10 is positioned within a native mitral valve, the upper region 30 can be generally positioned supra-annularly, the intermediate region 32 can be generally positioned intra-annularly, and the lower region 34 can be positioned sub-annularly. However, it is to be understood that in some situations, the positioning of the outer frame 16 relative to the annulus can differ. Moreover, it is to be understood that in some embodiments, the outer frame 16 can omit one or more of the upper region 30, the intermediate region 32, and/or the lower region 34.

The outer frame 16 can include a plurality of angularly spaced outer posts 36 extending from the respective apices 56 of the upper region 30 at the inlet end 22 of the prosthetic heart valve. In the illustrated embodiment, FIG. 1 shows the outer frame 16 has ten such posts 36, although a greater or lesser number of posts may be used. As best shown in FIG. 2, the inner frame 15 similarly may include a plurality of angularly spaced inner posts 38, each of which can be circumferentially aligned with a corresponding post 36 of the outer frame 16 to form a plurality of pairs of posts 36, 38 angularly spaced from each other along the inlet end 22. The inner and outer posts 36, 38 of each pair can be connected to each other with a suture and/or a fabric. The outer posts 38 and/or the inner posts 38 can be used to form a releasable connection with a delivery apparatus for securing the prosthetic heart valve 10 to the delivery apparatus when the prosthetic heart valve and the delivery apparatus are advanced through a patient's vasculature to a desired implantation site (e.g., the native mitral valve). The outer posts 38 and/or the inner posts 38 can also be used to form a releasable connection with a securement mechanism of a storage jar assembly, as further described below.

The frame assembly 12 may further include a plurality of angularly spaced anchoring features 40 (which can also be referred to as “anchoring legs” or “ventricular anchors”). The anchoring features 40 can extend from an outflow end of the inner frame body 24. As illustrated in FIG. 1, the anchoring features 40 may extend generally downwardly and radially outwardly from the outlet end of the inner frame body 24. When implanted in a native valve (e.g., a native mitral or tricuspid valve), the anchoring features 40 can extend behind and/or engage native tissue, such as the native leaflets and/or chordae tendineae, within a ventricle of a heart. As shown in FIG. 1, the anchoring features 40 can be covered or wrapped by respective covers 42, which can be formed from a relatively soft material, such as a fabric or natural tissue. In alternative embodiments, the anchoring features 40 can be components of the outer frame 16. For example, the anchoring features 40 can extend from an outlet end of the outer frame main body 26. In alternative embodiments, similar anchoring features can be provided at the inlet of the inner frame 15 or the outer frame 16 for engaging tissue within an atrium of a heart.

The prosthetic heart valve 10 can include one or more skirts for sealing against native tissue surrounding the prosthetic heart valve once implanted, for attaching other components (e.g., leaflets) to the frame assembly and/or for blocking the flow of blood through the open cells of the frame. As shown in FIG. 1, the prosthetic heart valve 10 can have an inner skirt 44 and an outer skirt 46. The inner skirt 44 can be disposed between the inner frame 15 and the outer frame 16 and can be attached to the outer frame 16 by sutures 48. The outer skirt 46 can be disposed around the outer frame 16 and can be attached to the outer frame by sutures 48. In some embodiments, the inner skirt 44 and the outer skirt 46 can be formed from a single piece of material that is folded at one end. In other embodiments, the inner skirt 44 and the outer skirt 46 can be formed from separate pieces of material. The skirts 44, 46 can be made of any of various suitable materials, including synthetic fabrics, such as polyethylene terephthalate (PET) fabric, or natural tissue (e.g., pericardial tissue).

As shown in FIG. 2, the valvular structure 14 may comprise a leaflet assembly comprising a plurality of leaflets 50 disposed within a lumen of the inner frame 15. In particular embodiments, the leaflet assembly comprises three leaflets 50, although a greater or fewer number of leaflets may be used in other embodiments. The leaflets 50 are configured to permit flow from the inlet end 22 of the prosthetic heart valve 10 to the outlet end 20, but to prohibit flow from the outlet end 20 of the prosthetic heart valve 10 to the inlet end. The leaflets 50 can be made of pericardial tissue (e.g., bovine pericardial tissue), biocompatible synthetic materials, or various other suitable natural or synthetic materials as known in the art.

The leaflet assembly can further include a liner 52. The liner 52 can be used to assist with fluid flow through and/or around the prosthetic heart valve 10, such as through the inner frame 15 and the valve leaflets 50. The liner 52 can surround at least a portion of the valve leaflets 50 and be connected to one or more of the valve leaflets 50. For example, as shown in the illustrated embodiment, the one or more valve leaflets 50 can be attached to the liner 52 (e.g., by sutures) along an arcuate or fixed edge of the valve leaflets 50. The liner 52 can extend from the arcuate or fixed edge of each leaflet 50 and extend upwardly towards an upper end of the inner frame 15. The liner 52 in turn can be attached to the inner frame 15, such as by sutures.

The outer frame 16 can be attached to the inner frame 15 at one or more attachment points. The outer frame 16 can be tautly attached to the inner frame 15 such that little to no relative movement between the inner frame 15 and the outer frame 16 occurs at the one or more attachment points. In other embodiments, the outer frame 16 and the inner frame 15 can be loosely attached such that some relative movement between the inner frame 15 and the outer frame 16 can occur at the one or more attachment points. Although the outer frame 16 and inner frame 15 are illustrated as separate components in FIG. 2, it is to be understood that outer frame 16 and inner frame 15 can be unitarily or monolithically formed. For example, the entire frame assembly 12 can be formed (e.g., laser cut) from a single piece of material.

In alternative embodiments, the prosthetic heart valve 10 can have a single frame, which can be formed with the outer posts 36, anchoring features 40, and/or other features described above in connection with frames 15 and 16. Examples of a prosthetic heart valve having a single frame are disclosed in Publication No. US 2016/0317301 and U.S. Pat. No. 10,350,062, which are incorporated herein by reference.

In particular embodiments, the frames 15, 16 are made of a self-expandable material, such as Nitinol. When constructed of a self-expandable material, the frames 15, 16 (and thus the prosthetic heart valve 10) can be crimped to a radially compressed state and restrained in the compressed state by insertion into a sheath or equivalent mechanism of a delivery catheter. Once inside the body at the desired implantation site (e.g., the native mitral valve), the prosthetic heart valve can be advanced from the delivery sheath, which allows the prosthetic heart valve to expand from the radially compressed state to a radially expanded state corresponding to its functional size.

In other embodiments, the frames 15, 16 can be made of any suitable plastically-expandable materials, such as stainless steel or a nickel-based alloy (e.g., a cobalt-chromium or a nickel-cobalt-chromium alloy), polymers, or combinations thereof. When constructed of a plastically-expandable material, the frames 15, 16 (and thus the prosthetic heart valve 10) can be crimped to a radially compressed state on a delivery catheter, such as on or adjacent an inflatable balloon or equivalent expansion mechanism. Once inside the body at the desired implantation site (e.g., the native mitral valve), the prosthetic can be expanded from the radially compressed state to a radially expanded state corresponding to its functional size by the inflatable balloon or the equivalent expansion mechanism.

Exemplary delivery apparatuses that can be used to implant the prosthetic heart valves disclosed herein are disclosed in Publication Nos. US 2016/0317301 and 2019/0008640, which are incorporated herein by reference.

FIG. 3 depicts an alternative embodiment of a prosthetic heart valve 100 that can be used with the storage jar assemblies disclosed herein. The prosthetic heart valve 100 comprises a frame assembly 102 and a valvular structure 104 supported by the frame 102. The frame assembly 102 defines an inlet end 106 and an outlet end 108 of the prosthetic heart valve 100. As illustrated in FIGS. 4 and 5, the frame assembly 102 in the illustrated embodiment includes an outer frame 110 and an inner frame 112. The outer and inner frames 110, 112 can comprise a plurality of interconnected struts 114 arranged in a lattice or diamond pattern. As shown in FIG. 3, the prosthetic heart valve 100 can also comprise an inner skirt 116 and an outer skirt 118. The skirts 116, 118 may be attached to the frame assembly 102.

As best illustrated in FIG. 4 the outer frame 110 can include an annular outer frame body 120. The outer frame body 120 can have an upper region 122, an intermediate region 124, and a lower region 126. In some situations, such as those in which the prosthetic heart valve 100 is placed within a native mitral valve, the upper region 122 can be generally positioned supra-annularly, the intermediate region 124 can be generally positioned intra-annularly, and the lower region 126 can be generally positioned sub-annularly. However, it is to be understood that in some embodiments, the outer frame 110 can omit one or more of the upper region 122, the intermediate region 124, or the lower region 126.

As best illustrated in FIG. 5, the inner frame 112 can include an annular inner frame body 128 and anchoring features 130. The inner frame body 128 can have a generally cylindrical shape such that it has a substantially constant diameter from an upper end (inlet end) to a lower end (outlet end) of the inner frame body. However, it is to be understood that, in alternative embodiments, the diameter of the inner frame body 128 can vary along its length. Although inner frame body 128 is described as generally having a cylindrical shape, it is understood that all or a portion of the inner frame body 128 may have a non-circular cross-section such as, but not limited to, a D-shaped cross-section.

The outer frame 110 can include a plurality of angularly spaced outer posts 132 extending from respective apices 134 at the upper region 122 near the inlet end 106 of the prosthetic heart valve 100. In one illustrated embodiment, as shown in FIG. 3, the outer frame 110 has eleven such outer posts 132, but a greater or lesser number of posts may be used. As best shown in FIG. 5, inner frame 112 may similarly include a plurality of angularly spaced inner posts 136 along the inlet end 106 of the prosthetic heart valve 100. Each of the angularly spaced inner posts 136 can be circumferentially aligned with a corresponding outer post 132 of the outer frame 110 to form a plurality of pairs of posts 132, 136 angularly spaced from each other along the inlet end 106. The posts 132, 136 of each pair can be connected to each other with a suture and/or a fabric. The outer posts 132 and/or the inner posts 136 can be used to form a resealable connection with a delivery apparatus for securing the prosthetic heart valve 100 to the delivery apparatus when the prosthetic heart valve and delivery apparatus are advanced through a patient's vasculature to a desired implantation site (e.g., the native mitral valve). The outer posts 132 and/or inner posts 136 can also be used to form a releasable connection with a securement mechanism of the storage jar assemblies described herein.

The frame assembly 102 may further include a plurality of angularly spaced anchoring features 130 (which can also be referred to as “anchoring legs” or “ventricular anchors”). The anchoring features 130 can extend from an outflow end of the inner frame body 128. As illustrated in FIG. 3, the anchoring features 130 may extend generally downwardly and radially outwardly from the inner frame body 128. When implanted in a native valve (e.g., a native mitral or tricuspid valve), the anchoring features 130 can extend behind and/or engage native tissue, such as the native leaflets and/or chordae tendineae, within a ventricle of a heart. As shown in FIG. 3, the anchoring features 130 can be covered or wrapped by respective covers 138, which can be formed from a relatively soft material such as fabric or natural tissue. In alternative embodiments, the anchoring features 130 can be components of the outer frame 110. For example, the anchoring features 130 can extend from the lower region 126 of the outer frame body 120. In alternative embodiments, similar anchoring features can be provided at the inlet end of inner frame body 128 or outer frame body 120 for engaging tissue with an atrium of a heart.

The prosthetic heart valve 100 can include one or more skirts for sealing against native tissue surrounding the prosthetic heart valve once implanted, for attaching other components (such as leaflets) to the frame assembly, and/or for blocking the flow of blood through the open cells of the frame. As shown in FIG. 3, the prosthetic heart valve 100 can have an inner skirt 116 and an outer skirt 118. The inner skirt 116 can be disposed between the inner frame 112 and the outer frame 110 and can be attached to the outer frame 110 with sutures or any other suitable attachment mechanism. The outer skirt 118 can be disposed around the outer side of outer frame 110 and can be attached to the outer frame 110 with sutures or any other suitable attachment mechanism. In some embodiments, the inner skirt 116 and outer skirt 118 may be formed from a single piece of material that is folded at one end. In other embodiments, the inner skirt 116 and the outer skirt 118 can be formed from separate pieces of material. The skirts 116, 118 can be made of any suitable materials, including synthetic fabrics or natural tissue.

As shown in FIG. 3, the valvular structure 104 may comprise a plurality of leaflets 140 disposed within a lumen of the inner frame 112. In some embodiments, the valvular structure comprises three leaflets 140, although a greater or fewer number of leaflets may be used in other embodiments. The leaflets 140 are configured to permit flow from inlet end 106 of the prosthetic heart valve 100 to outlet end 108, but to prohibit flow from the outlet end of the prosthetic heart valve 100 to the inlet end 106. The leaflets 140 can be made of pericardial tissue, biocompatible synthetic materials, or synthetic materials as known in the art.

The outer frame 110 can be attached to inner frame 112 at one or more attachment points. The outer frame 110 can be tautly attached to inner frame 112 such that little to no relative movement between the outer frame 110 and the inner frame 112 at the one or more attachment points. In other embodiments, the outer frame 110 and the inner frame 112 can be loosely attached, such that some relative movement between the outer frame 110 and the inner frame 112 can occur at the one or more attachment points. Although the outer frame 110 and the inner frame 112 are illustrated as separate components in FIGS. 4 and 5, it is to be understood that the outer frame 110 and the inner frame 112 can be unitarily or monolithically formed. For example, the entire frame assembly 102 can be formed (e.g., laser cut) from a single piece of material or additively manufactured.

In particular embodiments, the frames 110, 112 are made of a self-expandable material, such as Nitinol. When constructed of a self-expandable material, frames 110, 112 (and thus the prosthetic heart valve 100) can be crimped to a radially compressed state and restrained in the compressed state by insertion into a sheath or equivalent mechanism of a delivery catheter. Once inside the body at the desired implementation site (e.g., the native mitral valve), the prosthetic heart valve can be advanced from the delivery sheath, which allows the prosthetic heart valve to expand from the radially compressed state to a radially expanded state corresponding to its functional size.

In other embodiments, the frames 110, 112 can be made of any suitable plastically-expandable materials, such as stainless steel or a nickel-based alloy (e.g., a cobalt-chromium or a nickel-cobalt-chromium alloy), polymers, or combinations thereof. When constructed of a plastically-expandable material, frames 110, 112 (and thus the prosthetic heart valve 100) can be crimped to a radially compressed state on a delivery catheter, such as on or adjacent to an inflatable balloon or equivalent expansion mechanism. Once inside the body at the desired implantation site (e.g., the native mitral valve), the prosthetic can be expanded from the radially compressed state to a radially expanded state corresponding to its functional size by the inflatable balloon or the equivalent expansion mechanism.

Further details of the prosthetic heart valve 10 of FIGS. 1-2, the prosthetic heart valve 100 of FIGS. 3-5, and other prosthetic heart valves that can be used with the storage jar assemblies of the present disclosure are disclosed in Publication Nos. US 2016/0317301, US 2018/0055629 and US 2019/0262129, and U.S. Pat. No. 10,350,062, which are incorporated herein by reference.

In some embodiments, the storage jar assemblies disclosed herein may incorporate a lid having a valve securement mechanism. The valve securement mechanism can have a plurality of valve attachment features configured to releasably attach to corresponding features on a prosthetic heart valve, such as the outer posts 36. In some embodiments, the valve attachment features may be configured to hold the prosthetic heart valve in a partially compressed state. The lid may further comprise a lid attachment mechanism configured to releasably attach to corresponding features on ajar.

Referring now to the storage jar assembly embodiment shown in FIG. 6, a storage jar assembly 200 can include a jar 202. The jar 202 generally comprises a base 204, an upstanding side wall 206 extending upwardly from the base 204. The upper end portion of the wall 206 can form a mouth defining an opening at the upper end of jar 202. The jar 202 can be configured to receive a prosthetic heart valve, such as prosthetic heart valve 10. Although the following description of the storage jar assembly 200 proceeds with reference to the prosthetic heart valve 10, it should be understood that other prosthetic heart valves (e.g., prosthetic heart valve 100 or any of those disclosed in Publication Nos. US 2016/0317301, US 2018/0055629 and US 2019/0262129, and U.S. Pat. No. 10,350,062) can be used with the storage jar assembly 200.

The storage jar assembly 200 may also have a lid 208 that can be configured to be releasably attachable to the jar 202 and to a prosthetic heart valve 210. The lid 208 may also be configured to hold prosthetic heart valve 210 in a partially-compressed state. In the illustrated embodiment, the jar 202 has a cylindrical wall 206 defining a circular cross-sectional profile (in a plane perpendicular to a central longitudinal axis of the jar). In other embodiments, jar 202 can have plural wall segments that define other cross-sectional profiles (in a plane perpendicular to a central longitudinal axis of the jar), such as square, hexagonal etc.

Referring to FIGS. 7-10, the lid 208 can have an upper portion 212 and a downwardly depending side wall 214. The inner surface of the lid comprises a plurality of valve attachment features, which are configured to releasably attach to corresponding features on the frame a prosthetic heart valve. The inner surface of the lid can also comprise a lid attachment mechanism, which is configured to releasably attach to corresponding features on the jar. In FIGS. 7, 8 and 10, only the outer frame 16 of the prosthetic heart valve 10 is shown and the other components of the prosthetic heart valve are omitted for purposes of illustrating the attachment between the outer frame 16 and the lid 208.

As best shown in FIGS. 9 and 9A, an inner surface 216 of the upper portion 212 comprises a valve securement mechanism in the form of an annular projection or ring 218 (also referred to as an annular lip) having an inner peripheral edge 220 and an outer peripheral edge 222. The annular ring 218 can be formed with a plurality of valve attachment features in the form of a plurality of slots or notches 224 that are configured to receive the outer posts 38 of the outer frame 16 of the prosthetic heart valve 10. The notches 224 are circumferentially spaced from each other along an imaginary circle coincident with a circumference of the inner peripheral edge 220 of the annular ring 218. Each notch 224 can extend in a radial direction from the inner peripheral edge 220 partially through the ring 218 and can have a closed end 226 spaced inwardly from the outer peripheral edge 222. The inner peripheral edge 220 and the notches 224 can be slightly spaced from a central inner surface portion 228 of the lid to form a receiving space that accommodates tip portions of the outer posts 38, as further described below.

In alternative embodiments, the notches 224 can extend completely through the annular ring 218 from the inner peripheral edge 220 to the outer peripheral edge 222. In other embodiments, the notches 224 can extend from the outer peripheral edge 222 (i.e., the notches are open at the outer peripheral edge) partially through the annular ring 218 and have closed ends that are spaced from the inner peripheral edge 220.

The annular ring 218 in the illustrated embodiment is circular in shape, but it is to be understood that the ring may have other shapes, such as elliptical, D-shaped, or any other shape sufficient to accommodate the shape of the outer frame 16.

FIG. 10 shows the outer posts 38 disposed in the notches 224, which is effective to securely hold the prosthetic heart valve 10 relative to the lid 208. To attach the outer frame 16 to the lid 208, the outer posts 38 and/or the outflow end of the prosthetic heart valve 10 can be compressed or pinched a sufficient amount to allow the outer posts 38 to be inserted inside of the annular ring 218. Each outer post 36 can be aligned with a corresponding notch 224, after which the compression force on the outer posts 38 can be released to allow the posts to slide into the notches under the resiliency of the frame. Tip portions 58 of the outer posts 38 can be located in the space between the annular ring 218 and the adjacent surface portion 228 of the inner surface of the lid. The tip portions 58 have a width that is greater than the width of the notches 224, which prevents the prosthetic heart valve 10 from being pulled away from the lid in an axial direction while the outer posts 38 are positioned in the notches 224. Removal of the outer posts 38 from the notches 224 can be accomplished by compressing the prosthetic heart valve or just the inlet end of the prosthetic heart valve a sufficient amount to move the outer posts 38 radially inwardly until they are removed from the notches. Thereafter, the prosthetic heart valve 10 can be separated from the lid.

While the illustrated embodiment shows the outer posts 38 of the outer frame 16 secured within the notches 224, it should be noted that other components of the prosthetic heart valve can be secured within the notches. For example, in some embodiments, both the outer posts 38 of the outer frame 16 and the inner posts 38 of the inner frame 15 can be secured within the notches 224. In other embodiments, only the inner posts 38 of the inner frame 15 can be secured within the notches 224.

In some embodiments, the annular ring 218 and the notches 224 are sized such that the outer frame 16 (and the prosthetic heart valve) is not held in a state of compression once the outer posts 38 are placed within the notches 224. That is, after aligning the outer posts 38 with the notches 224 and releasing the compression force on the frame, the end of the outer frame 16 with the outer posts 38 can fully expand and the outer posts 38 are retained within the notches by the engagement of the tip portions 58 with the annular ring 218.

In other embodiments, the annular ring 218 and the notches 224 can be sized and/or shaped to retain the outer frame 16 (and the prosthetic heart valve 10) in a compressed or partially compressed state. The amount of compression under which the outer frame 16 (and the prosthetic heart valve 10) is retained can vary depending on the diameter of an imaginary circle coincident with the close ends 226 of the notches 224. Thus, when the outer posts 38 are placed within the notches 224, the outer posts 38 can expand radially outwardly to contact the closed ends 226, but prevent the posts from fully expanding, effectively retaining that end of the frame in a partially compressed state. The outer posts 38 therefore can exert an outward bias against the closed ends 226, which assists in retaining the posts within the notches and further increases the attachment force between the frame and the lid.

When the frame is formed from a self-expandable material (e.g., Nitinol), the inherent resiliency of the frame causes the outer posts 38 to expand within the notches 224. If the frame is formed from a plastically-expandable material (e.g., stainless steel), the outer posts 38 can still exhibit sufficient resiliency to self-expand after being compressed and then released within the notches 224 if the posts are not initially compressed to such an extent that causes plastic deformation of the outer posts 38. Thus, it should be understood that the lid 208 can be used to retain self-expanding frames and plastically-expandable frames. Although less desirable, in some embodiments, the frame can undergo at least some amount of plastic deformation when placing the outer posts 38 within the notches 224 and then re-expanded via an outside force (e.g., a manual force applied to the frame or the posts).

With continued reference to FIG. 9, the inner surface of the side wall 214 of the lid 208 may further comprise a storage jar attachment region 230. The storage jar attachment region may contain one or more storage jar attachment features configured to releasably attach to corresponding features on the exterior of the upper end portion of the wall 206 of the storage jar 202. In some embodiments, as illustrated in FIG. 9, the one or more storage jar attachment features may include helical threads 232 (also referred to as screw threads), which configured to engage with corresponding helical threads 232 on the upper end portion of the wall 206 of the storage jar 202.

While FIGS. 9 and 10 depict a lid configured to attach to a jar with helical threads, other storage jar attachment mechanisms can be used. For example, as illustrated in FIG. 11, the one or more jar attachment features disposed on jar attachment region 230 may comprise one or more features for forming a press-fit or snap-fit connection with the jar. For example, the jar attachment region 230 of the lid can comprise an annular ridge 252, and the upper end portion of the jar side wall 206 can comprise an annular lip 254 on the exterior of jar 202. The ridge 252 is configured to releasably engage with lip 254 when lid 208 is pressed onto the upper end portion of the jar side wall 206202. While the embodiment illustrated in FIG. 11 shows a ridge 252 with a generally triangular or sloped cross-section and a lip 254 with a generally rectangular cross-section, it is to be understood that the geometries of the ridge and the lip may have other configurations, such as a rectangular ridge 252 and a triangular or sloped lip 254, a configuration wherein one or both of the ridge and the lip have a cross-section that is a segment of a cylinder or sphere, or any other geometries suitable for a releasable engagement between the ridge and the lip.

FIG. 6 shows the fully assembled storage jar assembly 200 with the prosthetic heart valve 10 attached to the lid 208 and the lid 208 attached to the jar 202. During assembly (such as at the manufacturing site of the prosthetic heart valve), the assembler can attach the prosthetic heart valve 10 to the lid 208 as previously described, fill the jar with a hydrating solution (e.g., glutaraldehyde), and then place the lid on top of the jar and secure it place (e.g., by screwing the lid onto the jar). Desirably, a sufficient volume of hydrating solution is placed in the jar so as to fully immerse the leaflets 50 of the prosthetic heart valve.

In some embodiments, the leaflets 50 can be made of a material or chemically treated such that they can be stored without a hydrating solution within the jar. In such embodiments, the storage jar assembly 200 can comprise a prosthetic heart valve (e.g., prosthetic heart valve 10) attached to the lid 208 and stored inside the jar 202, which can be free of any liquids except for any moisture retained by the leaflets following a tissue treatment process. Methods for treating tissue leaflets for so-called dry storage are disclosed in U.S. Pat. No. 8,007,992 and U.S. Patent Publication No. 2009/0164005, filed Dec. 18, 2008, both of which documents are incorporated herein by reference.

In the fully assembled state, the assembly 200 can be shipped to end users (e.g., hospitals) and stored until the prosthetic heart valve is used in a heart valve replacement procedure. Prior to implantation, the user (e.g., a physician) can remove the lid from the jar and then remove the prosthetic heart valve from the lid, as previously described. Advantageously, the lid 208 securely retains the prosthetic heart valve in place relative to the lid to prevent or minimize damage to the prosthetic heart valve during shipping and storage. Further, removal of the prosthetic heart valve from the jar and the lid is relatively simple and easy compared to known storage assemblies, does not require any special tools, and avoids or minimizes contact and possible damage to the leaflets 50.

In alternative embodiments of the storage jar assembly disclosed herein, the lid may further comprise a valve holder or valve securement mechanism that is spaced below the side wall of the lid to position the prosthetic heart valve closer to the bottom of the jar. This may be done, for example, to enable a prosthetic heart valve to be fully-immersed in a hydrating fluid when stored inside the jar (or to fully immerse the prosthetic heart valve using a relatively smaller volume of a hydrating fluid, or to facilitate detachment of the prosthetic heart valve from the lid of the storage jar assembly). In these alternative embodiments, the prosthetic heart valve may be stored in a partially compressed state as previously described.

In an exemplary embodiment shown in FIG. 12, a storage jar assembly 300 can comprise a jar 302 and a lid 308. The jar 302 comprises a base 304 and a wall 306 defining an opening for the jar at an upper end thereof. The jar 302 can have the same configuration and features as described above for the jar 202 and therefore is not described further. The lid 308 can comprise an upper portion 312 and a side wall 314. The lid 308 can have the same configuration as the lid 308 described above except that it includes a securement mechanism for a prosthetic heart valve that is offset from the inner surface of the lid, and more specifically, spaced below a side wall 314 of the lid 308.

Although the following description of the storage jar assembly 300 proceeds with reference to the prosthetic heart valve 10, it should be understood that other prosthetic heart valves (e.g., prosthetic heart valve 100 or any of those disclosed in Publication Nos. US2016/0317301, US 2018/0055629 and US 2019/0262129, and U.S. Pat. No. 10,350,062) can be used with the storage jar assembly 300.

The valve securement mechanism (also referred to as an “attachment structure”) can comprise an annular ring 318 and one or more struts or posts 320. Similar to the annular ring 218, the ring 318 can be configured to be releasably attachable to the prosthetic heart valve 10. The annular lip 318 can have a thickness in the radial direction defined by an inner peripheral edge (not visible in FIG. 12) and an outer peripheral edge. Each of the one or more struts 320 has a lower end connected to the annular ring 318 and an upper end connected to an inner surface of the lid 308.

With continued reference to FIG. 12, the annular ring 318 may further comprise a plurality of valve attachment features in the form of notches 324. In some embodiments, as shown in FIG. 12, the notches 324 can extend from the inner peripheral edge of annular ring 318 partially through the annular ring, similar to the notches 224 shown in FIGS. 9 and 9A. In other alternative embodiments, the notches 324 can extend completely through the annular ring 318 from its inner peripheral edge to its outer peripheral edge 322. In other embodiments, the notches 324 can extend from the outer peripheral edge 322 partially through the annular ring 318. Similar to the notches 224, the notches 324 are configured to releasably attach to corresponding features of the prosthetic heart valve 10. For example, the notches 324 can be configured to receive the outer posts 38 of the outer frame 16 as shown, the inner posts 38 of the inner frame 15, the outer posts 38 and the inner posts 38, or other components of the frame assembly 12.

The prosthetic heart valve 10 can be attached to and removed from the annular ring 318 of the lid 308 in the same manner as described for the embodiment of FIGS. 6-10. Moreover, the annular ring 318 and the notches 324 can be configured to retain the prosthetic heart valve 10 in a fully expanded state, or in a partially compressed state, as previously described for the embodiment of FIGS. 6-10. As shown in FIG. 12, when the storage jar assembly 300 is in the fully assembled state with the prosthetic heart valve 10 attached to the annular ring 318 and the lid 308 is attached to the jar, the prosthetic heart valve is held closer to the bottom of the jar and is spaced from the side wall 314 of the lid. This can allow the prosthetic heart valve 10 to be fully immersed in a hydrating fluid using a relatively smaller volume of fluid as compared to the embodiment of FIG. 6. Also, by holding the prosthetic heart valve 10 outside of the space defined by the side wall 314 of the lid, it may be relatively easier to remove the prosthetic heart valve from the annular ring.

Referring now to FIG. 13, a storage jar assembly 400 according to another embodiment is shown. The storage jar assembly 400 includes ajar 402. The jar 402 generally comprises a base 404 and an upstanding side wall 406 extending upwardly from the base 404. The upper end portion of the wall 406 can form a mouth defining an opening at the upper end of the jar 402. The jar 402 can be configured to receive a prosthetic heart valve, such as prosthetic heart valve 10. The storage jar assembly can also include a lid 408, configured to releasably attach to the jar 402. Although the following description of the storage jar assembly 400 proceeds with reference to the prosthetic heart valve 10, it should be understood that other prosthetic heart valves, (e.g., prosthetic heart valve 100 or any of those discussed in Publication Nos. US2016/0317301, US2018/0055629 and US2019/0262129, and U.S. Pat. No. 10,350,062) can be used with the storage jar assembly 400.

The storage jar assembly 400 may also have a valve securement mechanism or valve holder 410 that can be configured to be received by the jar 402 and to receive the prosthetic heart valve 10 or the frame assembly 12 of the prosthetic heart valve 10. The valve holder 410 may be configured to hold the prosthetic heart valve 10 and/or the frame assembly 12 in a compressed or partially compressed state. As shown in FIGS. 13-15, in some embodiments, the valve holder 410 can have a plurality of valve retention members 412 and a base 414. In FIGS. 13 and 15, only the inner frame 15 of the prosthetic heart valve 10 is shown, and the other components of the prosthetic heart valve are omitted for the purpose of illustrating the interaction of the valve holder 410 and the inner frame 15 of the prosthetic heart valve 10.

In some embodiments, the base 414 has a circular cross-sectional profile as shown. The base 414 has an upper surface 416, a lower surface 417, and an outer peripheral edge 418 extending between the upper surface 416 and the lower surface 417. The diameter of the base 414 can be less than the diameter of the opening defined by the mouth at the upper end of the jar 402 and allow for the valve holder 410 to pass through the mouth at the upper end of the jar 402 as the valve holder is inserted into or removed from the jar. While the base 414 illustrated in FIGS. 13-15 is shown as having a circular cross-sectional profile, it is to be understood that base 414 may, in some embodiments, have a square cross-section, a hexagonal-cross section, a D-shaped cross-section, or any cross-section suitable for receiving the inner frame 15 of prosthetic heart valve 10.

Referring to FIGS. 13-15, the valve holder 410 may also have a plurality of valve retention members 412. The valve retention members 412 may be disposed on the upper surface 416 of the base 414 of the valve holder 410. In some embodiments, the valve retention members 412 may be positioned along the outer peripheral edge 418 of the base 414 of the valve holder 410. In alternative embodiments, valve retention members 412 may be inset from the outer peripheral edge 418 of the base 414 towards the center of the base.

In some embodiments, the positioning of valve retention members 412 relative to the outer peripheral edge 418 and the center of the base 414 of the valve holder 410 may be adjustable. In one embodiment best illustrated in FIG. 14, the base 414 further comprises a plurality of slots 420 angularly spaced from one another and extending from the outer peripheral edge 418 of the base 414 towards the center of the base, and each valve retention member 412 further comprises a projection 422. The slots 420 on the base 414 may be configured to receive the projections 422 of the valve retention members 412 and to permit the positioning of valve retention members 412 to be adjustable by sliding the projections 422 along the length of the slots 420. While FIG. 14 depicts the slots 420 disposed on the base 414 and the projections 422 disposed on the valve retention members 412, it is to be appreciated that in alternative embodiments, the projections might be disposed on the base 414 and the slots might be disposed on the valve retention members 412.

The valve retention members 412 can be secured to the base 414 by a plurality of fasteners, such as the illustrated screws 419. Each screw 419 can extend through a corresponding slot 420 and into a corresponding threaded bore in a valve retention member 412. Loosening the screws 419 allows the valve retention members 412 to be slid radially inwardly and outwardly along the upper surface of the base 414. Tightening the screws 419 fixes the positions of the valve retention members 412 relative to the base 414. The positions of the valve retention members 412 can be adjusted to adjust the amount of retention force that is applied to the prosthetic heart valve 10, as further described below, and/or accommodate prosthetic heart valves of different sizes.

The valve retention members 412 may be configured to contact a corresponding inner frame anchoring feature 40 of the inner frame 15 of prosthetic heart valve 10. As best illustrated in FIG. 16, the valve retention members 412 may be configured to hold the frame assembly 12 (and thus the prosthetic heart valve 10) in a compressed or partially compressed state. The degree of compression imparted on the prosthetic heart valve 10 may be determined by the positioning of the valve retention members 412 relative to the outer peripheral edge 418 of the base 414. In the illustrated embodiment, the contact between the valve retention members 412 and the inner frame anchoring features 40 pushes the inner frame anchoring features 40 towards the center of the base 414 and against the outer frame 16. In this fashion, both the inner frame 15 and outer frame 16, and therefore the entire frame assembly 12 of prosthetic heart valve 10 are at least partially compressed by the valve retention members 412. In other embodiments, the amount of compression can be selected to partially compress the tip portions of the anchoring features, but otherwise may not cause any corresponding compression of the outer frame 16.

While FIGS. 13, 15, and 16 show valve retention members 412 configured to contact corresponding inner frame anchoring features 40 of prosthetic heart valve 10, it is to be understood that in other embodiments, the valve retention members 412 can be configured to contact other portions of the frame assembly, such as the outer frame body 26, the anchoring features 28 of the outer frame 16, and/or the inner frame body 24.

The compressive strain imparted on the frame assembly 12 desirably is great enough that the outermost diameter of the prosthetic heart valve 10 is less than the inner diameter of the jar 402 (to allow the prosthetic heart valve to be easily inserted into and removed from the jar), and small enough that the prosthetic heart valve 10 may be kept under the imparted strain for the entire storage life of the prosthetic heart valve 10 without damaging the frame assembly or other components of the prosthetic heart valve. In particular embodiments, the compressive strain can be less than 6%, such as 3% or less or 1% or less.

In certain alternative embodiments, valve retention members can be configured to contact the corresponding inner frame anchoring feature 40 or other portions of the frame assembly without imparting a compressive strain to the frame assembly 12 while still retaining the prosthetic heart valve relative to the valve holder during shipping and storage. For example, in some embodiments, each valve retention member 412 can include a recessed portion 440 on the inner radially facing surface of the valve retention member 412. Each recessed portion 440 can receive a respective anchoring feature 40 or another portion of the frame assembly. When the prosthetic heart valve is positioned on the valve holder 410, the anchoring features 40 can be aligned with and at least partially inserted into the recessed portions 440 (see FIG. 15). Moreover, in lieu of or in addition to the recessed portions 440, portions of the anchoring features 40 can be positioned within the slots 420 (see FIG. 15). In some embodiments, the positioning of the anchoring features 40 in the recessed portions 440 and/or the slots 420 can retain the prosthetic heart valve relative to the valve holder without imparting any compressive stain on the frame assembly.

When the frame assembly 12 is formed from a self-expandable material (e.g., Nitinol), the inherent resilience of the frame causes the inner frame anchoring features 40 to press against the valve retention members 412 to cause the compressive strain on the prosthetic heart valve. If the frame is formed from plastically-expandable material (e.g., stainless steel, polymer), the inner frame anchoring features 40 can still exhibit sufficient resiliency to self-expand after being compressed and released within the valve holder 410, if the frame is not initially compressed to such an extent that causes plastic deformation of the anchoring features 40 or other components of the frame assembly. Thus, it should be understood that the valve holder 410 can be used to retain self-expanding frames and plastically-expandable frames. Although less desirable, in some embodiments the anchoring features 40 and/or other components of the frame assembly can undergo at least some amount of plastic deformation when retained by valve retention members 412, and then be re-expanded via an outside force (e.g., a manual force applied to the frame or the anchoring features).

As shown in FIGS. 13-15, the valve holder 410 may also have a column or shaft 424. The column 424 has a lower end portion 428 and an upper end portion 430. The lower end portion 428 may contact or be connected to the upper surface 416 of the base 414 of the valve holder 410. The column 424 may project away from the base 414 of the valve holder 410 in an axial direction such that, when the valve holder 410 is within the jar 402, the column 424 extends towards the mouth of the jar 402, as best illustrated in FIG. 13. While FIGS. 13-15 show the column 424 positioned at the center of the base 414, it is to be understood that, in some embodiments, the column 424 may be positioned at a different location on the base 414, such as between the peripheral edge 418 and the center of the base, or at the peripheral edge 418.

In certain embodiments, the column 424 may extend such that, when the valve holder 410 is within the jar 402, the upper end portion 430 of the column 424 may be placed at or near the mouth of the jar 402, as best seen in FIG. 13. In some embodiments, the upper end portion 430 of the column 424 is configured to come into contact with an inner surface of the lid 408 when the valve holder 410 is within the jar 402 and the lid 408 is attached to the jar 402. It is to be appreciated that these embodiments offer several advantages, such as facilitating the removal of the valve holder 410 from the jar 402 by a user or providing additional stability to the valve holder 410 during storage and transport of the storage jar assembly.

In some embodiments, best illustrated in FIG. 15, the column 424 can be configured to pass through the center of the frame assembly 12 of the prosthetic heart valve 10, such as through the center of the inner frame 15 and/or the outer frame 16 when the prosthetic heart valve is received by valve holder 410. However, it is to be understood that, in alternative embodiments, the column 424 may not pass through the center or any other portion of the frames 15, 16 of the prosthetic heart valve 10.

In some embodiments, as illustrated in FIG. 14, the column 424 can be cylindrical with a uniform circular cross-section. However, it is to be understood that column may have alternative geometries, such as a cross-section that varies along its length, or the column may have a different cross-sectional shape such as a square cross-section, a hexagonal cross-section, a D-shaped cross-section, or any other cross-section suitable for passing through the frames 15, 16 of the prosthetic heart valve 10 and/or facilitating the removal of the valve holder 410 from the jar 402.

Returning to FIG. 13, the storage jar assembly 400 may further include a lid 408 that can have an upper portion 432 and a downwardly depending side wall 434. The inner surface of the lid 408 can further comprise a storage jar attachment mechanism, which is configured to releasably attach to corresponding features on the jar 402. It is to be understood that the storage jar attachment mechanism of lid 408 may include any of the storage attachment features previously described, such as helical threads, screw threads, press-fit, or snap-fit attachment features.

In some embodiments, an inner surface of the upper portion 432 of the lid 408 may further comprise a column securing feature configured to receive upper end portion 430 of column 424 when the valve holder 410 is within the jar 402 and the lid 408 is attached to the jar 402. The column securing feature may be, for example, a recess or indent formed in the inner surface of the upper portion 432 with a geometry suitable for receiving the upper end 430 of a corresponding column 424.

In some embodiments, the upper end portion 430 of the column 424 can be connected to the upper portion 432 of the lid 408, which allows the valve holder 410 and a prosthetic heart valve 10 retained by the valve holder to be inserted into and removed from the jar 402 by manipulating the lid 408. In some embodiments, the upper end portion 430 of the column can be removably attached to the lid 408. This allows the valve holder to be disconnected from the lid after removing the valve holder and the prosthetic heart valve from the jar, which can facilitate removal of the prosthetic heart valve from the valve holder.

FIG. 13 shows the fully-assembled storage jar assembly 400, with the valve holder 410 placed within jar 402 and retaining the prosthetic heart valve 10. During assembly (such as at the manufacturing site of the prosthetic heart valve), the assembler can place the prosthetic heart valve 10 within the valve holder 410 as previously described, place the valve holder 410 and the prosthetic heart valve within jar 402, fill the jar with a hydrating solution (e.g., glutaraldehyde), place the lid on top of the jar, and then secure it in place (e.g., by screwing the lid onto the jar). Desirably, a sufficient volume of hydrating solution can be placed in the jar so as to fully immerse the leaflets 50 of the prosthetic heart valve.

In some embodiments, the leaflets 50 can be made of a material or chemically treated such that they can be stored without hydrating solution within the jar. In such embodiments, the storage jar assembly 400 can comprise a prosthetic heart valve held by valve holder 410 and stored within jar 402, which can be free of any liquids except for any moisture retained by the leaflets following a tissue treatment process. Methods for treating tissue leaflets for so-called dry storage are disclosed in U.S. Pat. No. 8,007,992 and U.S. Patent Publication No.

2009/0164005, filed Dec. 18, 2008, both of which documents are incorporated herein by reference.

In the fully assembled state, the storage jar assembly 400 can be shipped to end users (e.g., hospitals) and stored until the prosthetic heart valve is used in a heart valve replacement procedure. Prior to implementation, the user (e.g., a physician) can remove the lid from the jar, withdraw the valve holder from the jar, and then remove the prosthetic heart valve from the valve holder. The valve holder 410 securely retains the prosthetic heart valve 10 in place within the jar 402 to prevent or minimize damage to the prosthetic heart valve during shipping and storage. Further, the column 424 of the valve holder 410 facilitates the removal of the prosthetic heart valve 10 from the jar 402, as it is relatively easier to reach and grasp compared to known storage assemblies, does not require any specialized tools, and avoids or minimizes direct contact to the prosthetic heart valve 10, the leaflets 50, or the frame assembly 12.

Referring now to FIGS. 17-18, a lid 500 for a storage jar assembly according to another embodiment is shown. The lid 500 can include an upper portion 502 and a downwardly depending wall 504. The lid 500 can be configured to receive a prosthetic heart valve such as prosthetic heart valve 10. The lid 500 can further be configured to releasably attach to a valve storage jar (not shown) configured to receive the prosthetic heart valve 10, such as the jars previously disclosed, to form a storage jar assembly. Although the following description of the lid 500 proceeds with reference to the prosthetic heart valve 10, it should be understood that other prosthetic heart valves (e.g., prosthetic heart valve 100 or any of those discussed in Publication Nos. US 2016/0317301, US2018/0055629 and US 2019/0262129, and U.S. Pat. No. 10,350,062) can be used with the lid 500.

As shown in FIG. 17, the lid 500 may further comprise a valve release mechanism, such as a button 506 disposed on and/or within the upper portion 502 of the lid. As best illustrated in FIG. 18, the button 506 may be formed from a separate body set within an opening of the upper portion 502 of lid 500, forming a lid-button interface 508. The button 506 may be configured to slidably engage with the upper portion 502 of lid 500 along the lid-button interface 508. The slidable engagement of button 506 and upper portion 502 may allow the button 506 a range of movement with relation to the upper portion having both an upper limit and a lower limit. In some embodiments, the lower limit of the movement range is defined at a point when a lower surface 510 of the button 506 is flush with or lower than a lower surface 512 of the upper portion 502, and the upper limit of the movement range is defined at a point where the lower surface 510 of the button 506 is above the lower surface 512 of the upper portion 502 and/or where an upper surface 514 of the button 506 is elevated above an upper surface 516 of the upper portion 502.

The button 506 and the upper portion 502 of the lid may further be configured such that they form the valve attachment feature 518 on the inner surface of the upper portion 502 of the lid 500, beneath the button 506. In some embodiments, best illustrated in FIG. 18, the valve attachment feature 518 is a circular recession defined by the lower surface 510 of the button 506 and the lid-button interface. The valve attachment feature 518 may be configured to receive corresponding features of a frame 12 of a prosthetic heart valve 10, such as the angularly spaced outer posts 36 shown in FIG. 1. In some embodiments, the diameter of attachment feature 518 may be configured to be less than the diameter defined by the angularly spaced outer posts 36 in a fully-expanded state. In this way, the compressive forces exerted on angularly outer spaced posts 36 may cause interference forces sufficient to retain the prosthetic heart valve 10 in the valve attachment feature.

While the valve attachment feature 518 has been described as a circular recession, it is to be understood that any feature geometry suitable for retaining the angularly spaced outer posts 36 or other portions of the frame 12 of the prosthetic heart valve 10 may be used, such as an annular recession or groove, a polygonal recession, or a plurality of notches or indentations formed in the inner surface 512 of the upper portion 502 and/or the lower surface 510 of the button 506. In one embodiment, for example, notches or recesses (similar to notches 224) sized for receiving the outer posts 38 or other portions of the frame can be formed on the lower surface 512 and/or an inner surface of the upper portion 502 at the interface 508, and the button 506 can be configured to push the frame downwardly relative to the lid to push the outer posts 36 out of the notches. In some embodiments, the button 506 can be shaped to push the outer posts 38 radially inwardly away from the interface 508 and out of the notches as the button 506 is pressed downwardly relative to the upper portion 502 of the lid. In other embodiments, the outer posts 38 or other portions of the frame can be retained against the inner surface of the upper portion 502 at the interface 508 by the radial outward expansion of those portions of the frame against the adjacent inner surface of the upper portion 502.

Returning to FIG. 17, the inner surface of the lid 500 can further comprise a storage jar attachment mechanism (not shown), which is disposed on depending wall 504 and configured to releasably attach to corresponding features on the jar (not shown in FIGS. 17-18). It is to be understood that the storage jar attachment mechanism of lid 500 may include any of the storage attachment features previously described, such as helical threads, screw threads, press-fit, or snap-fit attachment features.

During assembly of a jar assembly comprising, in part, the lid 500 (such as at the manufacturing site of the prosthetic heart valve), the assembler can attach the prosthetic heart valve 10 to the lid 500 as previously described, fill the jar with a hydrating solution (e.g., glutaraldehyde), and then place the lid on top of the jar and secure it place (e.g., by screwing the lid onto the jar). Desirably, a sufficient volume of hydrating solution is placed in the jar so as to fully immerse the leaflets 50 of the prosthetic heart valve.

In a fully-assembled storage state, partially illustrated in FIG. 17, the lid 500 may be configured such that corresponding features of the prosthetic heart valve 10, such as the angularly spaced outer posts 36 or other elements of the frame 12 rest within the valve attachment feature 518. The prosthetic heart valve 10 thus may depend from the lid 500 and be contained within the valve storage jar in the fully-assembled storage state. In possible embodiment, when a jar assembly including the lid 500 is in the fully-assembled storage state, the button 506 may be near the upper limit of movement relative to upper portion 502 of lid 500.

In the fully-assembled storage state, the storage jar assembly including the lid 500 can be shipped to end users (e.g., hospitals) and stored until the prosthetic heart valve is used in a heart valve replacement procedure. Prior to implementation, the user (e.g., a physician) can press the button 506, moving the button 506 downwards relative to both the upper portion 502 of the lid 500 and the prosthetic heart valve 10, in the direction of arrow 520 in FIG. 18, causing the frame 12 or the angularly spaced outer posts 36 of the prosthetic heart valve 10 to be pushed or ejected from the valve attachment feature 518. In some embodiments, the prosthetic heart valve can be released prior to removing the lid from the jar, which causes the prosthetic heart valve 10 to detach from the lid 500 and become submerged or partially submerged in the hydrating solution (e.g., glutaraldehyde). Thereafter, the user can remove the prosthetic heart valve from jar just prior to loading the prosthetic heart valve onto the delivery device.

In other embodiments, the lid 500 can be removed from the jar while the prosthetic heart valve is still attached to the lid, after which the user can push the button 506 to release the prosthetic heart valve from the lid. Advantageously, this configuration allows a user to detach the prosthetic heart valve from the lid 500 while minimizing direct contact with the prosthetic heart valve and without requiring any tools, thereby facilitating the removal of the prosthetic heart valve from the storage jar assembly, and preventing or minimizing damage to the prosthetic heart valve.

In some embodiments, the lid 500 can include a locking feature or locking element that prevents inadvertent movement of the button 506 during shipping, storage and handling of the assembly prior to intended removal of prosthetic heart valve from the lid. The locking feature can be moved between a locked position and an unlocked position. In the locked position, the locking feature can contact and resist movement of the button 506. In the unlocked position, the locking feature is removed from contact with the button 506 and allows it to pushed relative to the upper portion 502 in order to release the prosthetic heart valve from the lid.

In some embodiments, the lid 500 can include a biasing element, such as a spring (e.g., a coil spring), configured to resiliently bias the button 506 to its upper limit of travel. When releasing the prosthetic heart valve from the lid, the user can press the button downwardly against the bias of the biasing element.
