Description

FIELD

The present disclosure relates to soft tissue implant systems, instruments, and related methods. The present disclosure relates to podiatric and orthopedic implants and surgery related to repairs of soft tissue and/or bone. More specifically, but not exclusively, the present disclosure relates to instruments, implants, systems, assemblies, and methods for joining soft tissue to soft tissue, soft tissue to bone, and bone to bone.

BACKGROUND

The plantar plate is a thick ligamentous (fibrocartilaginous) structure on the bottom of the foot under a metatarsophalangeal joint (MTP joint). A plantar plate attaches to a metatarsal bone and a corresponding proximal phalanx bone. A plantar plate provides stability to the MTP joint by withstanding compressive loads from the metatarsal head and tensile loads in line with the toe axis. A plantar plate also cushions the bottom of an MTP joint and the distal head of a metatarsal while standing, walking, running, and the like. A plantar plate also helps bring the corresponding toe toward the floor while standing.

A plantar plate may become torn or otherwise compromised, such as due to biomechanical abnormalities and/or imbalances in the foot that cause overload of one of the metatarsals and/or MTP joints. Examples of biomechanical abnormalities and/or imbalances include a long first metatarsal, a short second metatarsal, a short third metatarsal, an untreated metatarsus adductus deformity (e.g., a pigeon toe deformity), arthritis of the great toe (first metatarsal, first proximal phalanx and/or first distal phalanx), and prior cortisone injection into a plantar plate.

The tissue of the plantar plate itself may become attenuated, tear or otherwise become segmented along its length between corresponding metatarsal and proximal phalanx bones. Alternatively, a plantar plate may tear from or otherwise become decoupled from corresponding metatarsal or proximal phalanx bones. A torn plantar plate typically causes persistent ball of the foot pain and/or changes in the position/alignment of the affected toe and/or adjacent toe(s) (e.g., hammertoe). Both acute and, more commonly, chronic injuries to the plantar plate can cause a range of injury types, such as instability (particularly in the 2nd and 3rd MTP joints, medial deviation of the toe, “crossover toe”, pain and discomfort, for example).

Other tissues and/or bones of the foot, and other parts of a mammalian (e.g., human) body, similarly may become torn or otherwise be segmented or separated such that joining of the portions of the tissues and/or bones may be anatomically and/or physiologically advantageous or desirable. For example, the human hand includes a palmar plate. The palmar plate is an analogous structure to the plantar plate. A palmar plate is associated with each metacarpophalangeal joint (MCP joint) and each interphalangeal joint in the hand. Like the plantar plate, the palmar plate may tear.

Typical plantar plate repair options include suturing/re-approximating the tear in the plantar plate tissue to induce healing, or re-attaching the tissue to the insertion point at the base of the proximal phalanx. Current systems for plantar plate repair (and repairs of other tissues and/or bones of the foot, and other parts of the human body) tend to be bulky and/or complex. Current systems also typically require multiple and/or relatively large through holes to be formed per tissue and/or bone connection in order to join/repair the portions, which can weaken the construct.

All-suture soft anchor implants generally rely on bone quality and consistency for deployment. When tension is applied to anchors of an implant, those anchors deform within the cancellous bone space and deploy against the cortical bone to provide secure anchoring. In cases where bone quality or consistency is not optimal, these anchors may fail to deploy. Products can have up to about a ten percent non-deployment rate.

Thus, there is a need for instruments, implants, systems, assemblies, and methods for plantar plate repair, and joining of other tissues and/or bones of the foot and other parts of a mammalian (e.g., human) body, that are compact, maneuverable and simple to use. There is also need for tissue and/or bone repair/joining instruments for deployment of implants, systems, assemblies, and methods that do not require a plurality of and/or relatively large through holes formed in each of the joined tissue and/or bone segments.

The present disclosure is directed to overcoming these and other deficiencies in the art.

DETAILED DESCRIPTION

In this detailed description and the following claims, the words proximal, distal, anterior or plantar, posterior or dorsal, medial, lateral, superior and inferior are defined by their standard usage for indicating a particular part or portion of a bone or implant according to the relative disposition of the natural bone or directional terms of reference. For example, “proximal” means the portion of a device or implant nearest the torso, while “distal” indicates the portion of the device or implant farthest from the torso. As for directional terms, “anterior” is a direction towards the front side of the body, “posterior” means a direction towards the back side of the body, “medial” means towards the midline of the body, “lateral” is a direction towards the sides or away from the midline of the body, “superior” means a direction above and “inferior” means a direction below another object or structure. Further, specifically in regards to the foot, the term “dorsal” refers to the top of the foot and the term “plantar” refers the bottom of the foot.

Similarly, positions or directions may be used herein with reference to anatomical structures or surfaces. For example, as the current implants, devices, instrumentation, and methods are described herein with reference to use with the bones of the foot, the bones of the foot, ankle and lower leg may be used to describe the surfaces, positions, directions or orientations of the implants, devices, instrumentation and methods. Further, the implants, devices, instrumentation, and methods, and the aspects, components, features and the like thereof, disclosed herein are described with respect to one side of the body for brevity purposes. However, as the human body is relatively symmetrical or mirrored about a line of symmetry (midline), it is hereby expressly contemplated that the implants, devices, instrumentation, and methods, and the aspects, components, features and the like thereof, described and/or illustrated herein may be changed, varied, modified, reconfigured or otherwise altered for use or association with another side of the body for a same or similar purpose without departing from the spirit and scope of the invention. For example, the implants, devices, instrumentation, and methods, and the aspects, components, features and the like thereof, described herein with respect to the right foot may be mirrored so that they likewise function with the left foot. Further, the implants, devices, instrumentation, and methods, and the aspects, components, features and the like thereof, disclosed herein are described with respect to the foot for brevity purposes, but it should be understood that the implants, devices, instrumentation, and methods may be used with other bones of the body having similar structures.

Generally stated, disclosed herein are instruments, implants, systems, assemblies, and methods for joining soft tissue to soft tissue, soft tissue to bone, and bone to bone. The implants, systems, assemblies and methods may be used for repairing a torn plantar plate of a metatarsophalangeal joint (MTP joint). While the instruments, implants, systems, assemblies, and methods may be illustrated and described in the present disclosure in the context of plantar plate repair, the instruments, implants, systems, assemblies, and methods may equally be employed or may be adapted without undue experimentation to join any soft tissue to any soft tissue, any soft tissue to any bone, or any bone to any bone. For example, the instruments, implants, systems, assemblies, and methods may be equally employed to repair/join any other tissue and/or bone segments or portions of the foot or other parts of the mammalian (e.g., human) body, such as but not limited to a torn palmar plate.

The instruments, implants, systems, assemblies, and related methods for joining soft tissue to soft tissue, soft tissue to bone, and bone to bone of the present disclosure may be similar to, such as include at least one feature or aspect of, the implants, systems, assemblies and related methods disclosed in U.S. Provisional Pat.

Application No. 62/883,429, filed on Aug. 6, 2019, and entitled Soft Tissue Implant Systems, Instruments and Related Method; and/or International PCT Application No. PCT/US2019/064741, filed on Dec. 5, 2019, and entitled Soft Tissue Implant Systems, Instruments and Related Methods, which are incorporated herein by reference in their entireties.

Referring to the drawings, wherein like reference numerals are used to indicate like or analogous components throughout the several views, and with particular reference to FIGS. 1-17, there is illustrated an exemplary embodiment of a drill guide and inserter system 100 for joining soft tissue to soft tissue, soft tissue to bone, or bone to bone according to the present disclosure.

FIGS. 1-17 illustrate an exemplary drill guide and inserter system, instrument, device or apparatus 100 for facilitating implantation of an implant system in accordance with the present disclosure. The drill guide and inserter system 100 is configured to create one or more through holes in one or more bones or tissues and to implant an implant system into/through the one or more through holes in the one or more bones or tissues.

As shown in FIGS. 1-4 and 9-14, the drill guide and inserter system 100 includes a handle portion or component 108, an inserter portion or component 138 (see, e.g., FIGS. 9-13), and a guide portion or component 122 that are configured to nest or otherwise couple together. As shown in FIGS. 1-4, the handle portion 108 is manually engageable and includes a first coupling portion 118 of the handle portion 108 and a second coupling portion 120 of the handle portion 108. The handle portion 108 may further be proximate to inserter portion 138 or a component that extends from or past a distal end 112 of the handle portion 108 (e.g., the second coupling portion) and defines a bone engagement free end 130.

As shown in FIGS. 1-4, the handle portion 108 of the drill guide and inserter system 100 comprises both a proximal end 110 of the handle portion 108 and a distal end 112 of the handle portion 108. The handle portion 108 is configured to allow a user to securely grasp the handle portion 108 using one hand and position the guide portion 122 and bone engagement free end 130 of the insertion portion 132 and/or inserter portion 138 against a bone (e.g., a plantar side of a proximal phalanx). In one embodiment, the handle portion may include a distal projection to further allow for a user to securely grasp the handle portion 108 using one hand and position the guide portion 122 and the free end of the insertion portion 132 and/or inserter portion 138 against a bone (e.g., a plantar side of a proximal phalanx). The handle portion 108 is also configured to allow the user to secure the guide portion 122 and tip portion 134 of the inserter portion 138 against a bone via one hand (e.g., a plantar side of a proximal phalanx) by applying pressure to the drill guide and inserter system 100 via the user’s thumb against the proximal side of the handle, and potentially wrapping one or more fingers of the user’s hand around the opposing side of the bone (e.g., the dorsal aspect of the patient’s foot) to provide back pressure.

As further shown in FIGS. 1, 2, 9, and 10, for example, the tip portion 134 of the insertion portion 132 of inserter portion 138 may provide at least one relatively sharp point, tip or tooth that may securely engage bone to provide stability of the placement of the drill guide and inserter system 100 and the inserter portion 138 against the bone while the guide portion 122 surrounds the inserter portion 138, while in use. For example, in one embodiment, the tip portion 134 of the insertion portion 132 comprises a plurality of angularly or circumferentially spaced teeth configured to engage bone, as shown in FIGS. 1, 2, 9 and 10.

The handle portion 108 may include on the proximal end 110 of the handle portion 108 a first coupling portion 118. The first coupling portion 118 may include a distal end 117 which may be adjacent to the proximal end of 112 of the handle and may further include a proximal end 115 which may be adjacent to an end cap portion 102. The handle portion 108 may further include on the distal end 112 of the handle portion 108 a second coupling portion 120. The second coupling portion 120 may include a distal end 121 which may be adjacent to the inserter portion 138 and may further include a proximal end 119 which may be adjacent to the distal end 110 of the handle portion 108.

The handle portion 108 may include an inserter aperture or cavity 116 (see FIG. 4) extending from the proximal end 110 of the handle portion 108 to the distal end 112 the handle portion 108 and toward the inserter portion 138 and the guide portion 122 and may be configured to accept therein or mate with a first coupling portion 118 at the proximal end 110 of the handle portion 108 and a second coupling portion 120 at the distal end 112 of the handle portion 108 as shown in FIGS. 4 and 14, for example. The cavity 116 may be open or exposed at the distal end 112 of the handle portion 108 and may be open or exposed at the proximal end 110 of the handle portion 108. The cavity 116 may further be open or exposed at the distal end 121 of the second coupling portion 120 of handle portion 108 and may be open or exposed at the proximal end 119 of the second coupling portion, 120 of handle portion 108 thereby forming a slot or opening 136 (see FIGS. 13 and 14) at the distal end 121 of the second coupling portion 120.

As shown in FIGS. 5 and 13-15, the inserter portion 138 and the handle portion 108 are cannulated, hollow or otherwise include cooperating through holes that form an internal passageway or through hole 140 that may extend through the inserter portion 138 from the tip portion 134 of the inserter portion 138 and the tip portion of the insertion portion 132 to the proximal end 110 of the handle portion 108. The internal passageway 140 may also be open or exposed at the tip portion 134 of the inserter portion 138 and the tip portion of the insertion portion 132 and is also open or exposed at the proximal end 110 of the handle portion 108. The internal passageway 142 through the handle portion 108 may extend for the length of the handle portion 108 and may extend for the length of the first coupling portion 118 of the handle portion 108 and the second coupling portion 120 of the handle portion 108. The inserter portion 138 may be surrounded by guide portion 122 to aid in deployment of an anchor during implant surgery.

The internal passageway 140 is configured to accept a corresponding drilling member (such as a k-wire, drill bit, or other elongate drilling mechanism) therethrough. With the tip portion 134 of the insertion portion 132 engaged with a bone, the inserter portion 138 may be introduced into the internal passageway 140 at the proximal end 110 of the handle portion 108, and advanced through internal passageway 140 of the handle portion 108 and the inserter portion 138 to the bone, all while the inserter portion 138 is proximate to a guide portion 122. The drilling member can then be rotated or otherwise utilized to create a hole or aperture into, and potentially through, the bone. At least a portion of the internal passageway 140 of the inserter portion 138 may approximate the cross-sectional size (e.g., diameter) of the drilling member to guide the drilling member and prevent the drilling member from wandering and/or angling during a drilling operation.

The inserter portion 138, the handle portion 108, and the guide portion 122 may include one or more holes, slots, or openings that extend through the exterior surfaces thereof to the internal passageway 140. The inserter portion 138, the handle portion 108, and the guide portion 122 may also include holes that extend from the tip portion 134 of the insertion portion 132 of inserter portion 138 to the proximal end 110 of the handle portion 108. The one or more holes may be in communication with the exterior of the drill guide and inserter system 100 (e.g., the exterior of the handle portion 108 and/or the exterior of the guide portion 122) and the internal passageway 140 and the internal passageway 142 to provide access to and from the internal passageway 140 and the internal passageway 142. The width of the hole is less than the cross-sectional size of the drilling member to prevent the drilling member from disengaging from the internal passageway 140 and the internal passageway 142 during a drilling operation. In one embodiment, the width of the hole may be greater than a cross-sectional size of the strands of a tensioning suture and the strands of a shuttle suture of an implant coupled or loaded onto the inserter portion 138.

As shown in FIGS. 1-4 and 7-12, one end of the inserter portion 138 is attached to the manually engageable handle portion 108 and the opposing end of the inserter portion 138 is attached to an insertion portion 132 that extends from or past a distal end 112 of the handle portion 108 and defines an implant holder free end or tip portion 134. The insertion portion 132, tip portion 134, and bone engagement free end of inserter 130 may extend beyond the guide portion 122. As noted above, the distal end 112 of the handle portion 108 may include a second coupling portion 120. The second coupling portion 120 has a distal end 121 that is adjacent to the inserter portion 138 and also has a proximal end 119 that is adjacent to the distal end 112 of the handle portion 108. The second coupling portion 120 is configured to extend into and securely mate with the cavity 116 extending from the proximal end 110 of the handle portion 108 to the distal end 112 of the handle portion 108 of the drill guide and the inserter system 100. The handle portion 108 may also include a stop surface proximate to the second coupling portion 120 of the handle portion 108 that is configured to abut against the distal end 110 of the handle portion 108 of the drill guide and inserter system 100 when the second coupling portion 120 of handle portion 108 is fully seated within the cavity 116. The handle portion 108 may also include a stop surface proximate to the first coupling portion 118 of the handle portion 108 that is configured to abut against the proximate end 110 of the handle portion 108 of the drill guide and inserter system 100 when the first coupling portion 118 of the handle portion 108 is fully seated within the cavity 116.

The handle portion 108 of the drill guide and inserter system 100 may include the internal cavity or passageway 142 that is in communication with the passageway 140 of the inserter portion 138 when the inserter portion 138 is fully mated with the handle portion 108. The handle portion 108 may include one or more of a slot, hole, or opening 114 that extends from the exterior surface the handle portion 108 to the internal passageway 142. The inserter portion 138 may include an internal passageway 140 which may extend from the tip portion 134 of the insertion portion 132 of the inserter portion 138 to the proximal end 110 of the handle portion 108, or may extend from the tip portion 134 of the insertion portion 132 of the inserter portion 138 to the proximal end 119 of the second coupling portion 120 of the handle portion 108. The internal passageway 140 may be in communication with the exterior of the handle portion 108 and the internal passageway 140. The slot 114 may also provide access to and from the internal passageway 140.

The proximal end 110 of the handle portion 108 may define an end surface that can be utilized to apply pressure to the inserter portion 138. In some embodiments, the proximal end 110 of the handle portion 108 may be defined by a removable end cap portion 102 that closes off and/or mates within the internal passageway 142 of the handle portion 108. The end cap portion 102 may include a distal end 106 of the end cap portion which may be adjacent to the first coupling portion 118 of the handle portion 108. The first coupling portion 118 of the handle portion 108 is further adjacent to the proximal end 110 of the handle portion 108. The end cap portion 102 may further include a proximal end 104 of the end cap portion 102. The end cap portion 102 may be a solid opaque end cap, a solid transparent end cap, and/or it may optionally include one or more holes.

The insertion portion 132 comprises a stiff elongate post or like member or portion. The insertion portion 132 is configured to extend through the entirety of the passageway 140 of the inserter portion 138 from the proximal end 110 of the handle portion 108 or from the proximal end 104 of the end cap portion 102 through the tip portion 134 (i.e., it may extend through the entirety of the passageway 142 of the handle portion 108 and the entirety of the passageway 140 of the inserter portion 138) when the second coupling portion 120 of the handle portion 108 is fully seated within the internal passageway 140 through the inserter portion 138, as shown in FIGS. 1-4, 7, and 8.

Also, as shown in FIGS. 1-4 and 7-12, the guide portion or component 122 may be configured to envelope or surround the inserter portion 138 and nest or otherwise couple together with the handle portion 108, via the second coupling portion 120 in the drill guide and inserter system 100. The guide portion 122 is proximate to a distal end to the medial end component 126, and the medial end component 126 is further proximate to the distal end to the distal end component 128. The medial end component 126 is thereby intermediate the guide portion 122 and the distal end component 128. The guide portion 122, the medial end component 126, and the distal end component 128 may, in one embodiment, surround the inserter portion 138 and attach to the distal end 121 of the second coupling portion 120 of the handle portion 108. The guide portion 122 may further include a feature to hold the guide portion static during deployment. For example, the guide portion 122 may include a guide handle 124 which may be useful to aid in deployment of an anchor. The guide portion 122 may be inserted into a bone hole prepared for insertion of an implant and may, therefore, be comprised of any material suitable for performing such function. Examples of materials may include, but are not limited to, a polymer, a plastic, and/or a metal. In one embodiment, the guide portion 122 is comprised of a thin-walled and optionally a flexible material. The guide portion 122 may be slotted and contain holes across the surface of the guide portion 122.

As shown in FIGS. 16 and 17, the guide portion 122 may be inserted behind an anchor of an implant and may further be kept in place while the inserter portion 138 and insertion portion 132 are removed during implant application. An anchor may deploy against the guide portion 122 rather than needing to rely on the cortical wall of the bone for such deployment and obviate the need to depend solely on the native bone quality and consistency for anchor deployment during implantation. The guide portion 122 may be a separate accessory instrument (as shown, for example, in FIGS. 16 and 17) or the guide portion 122 may be a removable or non-removeable feature of the inserter portion 138. The guide portion 122 may be in the form of a sleeve, in one embodiment, or, alternatively, may take the form other than a sleeve, such as a blunt obturator, a threaded slotted screw, and/or a cannulated screw/button, or any combination thereof. A suture coming from the anchor may go inside of the internal passageway 140 of the inserter portion 138 or, in an alternative embodiment, a suture may go on the outside of the inserter portion 138.

The implant holder tip portion 134 of the insertion portion 132 is configured to hold or retain an anchor of an implant, such as a tension anchor and/or a shuttle anchor of an implant system. An anchor of an implant may thereby be pre-loaded on the tip portion 134, and one or more other portion of an implant may be coupled to or provided in/on the insertion portion 132. For example, a tension anchor and/or a shuttle anchor may be retained on the tip portion 134 of the inserter portion 138, and a tensioning suture and/or a shuttle suture may be provided/extend through the passageway 142 within the handle portion 108. A tension anchor or the shuttle anchor that is not retained on the tip portion 134 and/or a needle of an implant may be housed within the passageway 140 of the inserter portion 138 or coupled to the exterior of the inserter portion 138, for example. A tensioning suture and/or the shuttle suture, and/or a needle, may be removably coupled to a clip, post or another portion or mechanism of the inserter portion 138 such that a tensioning suture and/or a shuttle suture may apply tension to the tension anchor or the shuttle anchor that is on the tip portion 134 to releasably retain the tension anchor/shuttle anchor on the tip portion 134. The drill guide and inserter system 100 may be pre-loaded with an implant system.

When the inserter portion 138 is fully mated with the handle portion 108, the drill guide and inserter system 100 is configured such that a tension anchor and/or a shuttle anchor of an implant that is retained on the tip portion 134 is positioned past the tip portion 134 of the inserter portion 138, and any tensioning sutures and/or the shuttle sutures extend through the passageway 140 of the inserter portion 138 and the passageway 142 of the handle portion 108. However, tensioning sutures and shuttle sutures may be removed from the passageway 140 of the inserter portion 138 and the passageway 142 of the handle portion 108 by passing a tensioning suture and/or a shuttle suture through the hole 114 of the handle portion 108 and the slot of opening 136 on the distal end of the second coupling portion 120 of the handle portion 108.

As shown in FIG. 15, the implant holder tip portion 134 of the insertion portion 132 of the inserter portion 138 may include a forked free end 144 and a pair of grooves 146 extending proximally from the base of the forked free end 144 along differing (e.g., opposing) sides of the insertion portion 132. The forked free end 144 and at least one groove 146 are configured to retain or mate with an anchor of an implant system (e.g., a tension anchor or a shuttle anchor of an implant system) with a medial portion of an anchor extending over the base of the forked free end 144 between the tines or arms thereof and end portions of an anchor extending within and along the grooves 146. The implant holder tip portion 134 may be configured such that the implant holder tip portion 134 is stiff, and thereby utilized to insert or pass an anchor retained thereon into and through a hole in at least soft tissue and/or a bone.
