The foregoing Examples are just that, and should not be read to limit or otherwise narrow the scope of any of the inventive concepts otherwise provided by the instant disclosure. While multiple examples are disclosed, still other embodiments will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative examples. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature rather than restrictive in nature.
The accompanying drawings are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this specification, illustrate embodiments, and together with the description serve to explain the principles of the disclosure.
This disclosure is not meant to be read in a restrictive manner. For example, the terminology used in the application should be read broadly in the context of the meaning those in the field would attribute such terminology.
With respect to terminology of inexactitude, the terms “about” and “approximately” may be used, interchangeably, to refer to a measurement that includes the stated measurement and that also includes any measurements that are reasonably close to the stated measurement. Measurements that are reasonably close to the stated measurement deviate from the stated measurement by a reasonably small amount as understood and readily ascertained by individuals having ordinary skill in the relevant arts. Such deviations may be attributable to measurement error, differences in measurement and/or manufacturing equipment calibration, human error in reading and/or setting measurements, minor adjustments made to optimize performance and/or structural parameters in view of differences in measurements associated with other components, particular implementation scenarios, imprecise adjustment and/or manipulation of objects by a person or machine, and/or the like, for example. In the event it is determined that individuals having ordinary skill in the relevant arts would not readily ascertain values for such reasonably small differences, the terms “about” and “approximately” can be understood to mean plus or minus 10% of the stated value.
Persons skilled in the art will readily appreciate that various aspects of the present disclosure can be realized by any number of methods and apparatuses configured to perform the intended functions. It should also be noted that the accompanying drawing figures referred to herein are not necessarily drawn to scale, but may be exaggerated to illustrate various aspects of the present disclosure, and in that regard, the drawing figures should not be construed as limiting.
Various aspects of the present disclosure are directed toward to implantable medical devices such as device for shunting and/or occluding bodily fluids or structures. In certain instances, the various aspects of the present disclosure relate to methods and devices for treating heart failure by reducing elevated blood pressure in a heart chamber by creating a pressure relief shunt. Additionally, some embodiments relate to methods and devices for customizing, adjusting or manipulating the flow of blood through the shunt in order to enhance the therapeutic effect of the pressure relief shunt.
A sheath 140 and constraining and/or release lines (not shown) may be used to facilitate deployment of the device 100. For example, a first side of the device 100 that includes the first frame component 110 may be released after the sheath 140 is advanced through the septum and to the RA, and the second frame component 120 that includes the second frame component 120 may be released on the LA side of the septum. A conduit portion 130 (e.g., shown in
In certain instances, the first frame component 110 includes a first set of elongate elements 112, and the second frame com ponent 120 includes a second set of elongate elements 122. The frame components 110, 120, including and for example the elongate elements 112, 122, may be discrete and separate from one another. For example, the first frame component 110 forms a first side 100a of the device 100 and the second frame component 120 forms a second side 100b of the device 100. The first frame component 110 being discrete and separate from the second frame component 120 does not enter into the second side 100b of the device and the second frame component 120 being discrete and separate from the first frame component 110 does not enter into the first side 100a of the device.
In certain instances, the first and second frame components 110, 120 are non-contiguous with one another. The first and second frame components 110, 120 being non-contiguous with one another allows the first and second frame components 110, 120 to be distinct and separate from one another. In addition, the first and second frame components 110, 120 are free to move, in response to movement of the patient’s anatomy, separate from one another. In this manner, forces acting on one of the first and second frame components 110, 120 are maintained within the other of the first and second frame components 110, 120. The forces acting on one of the first and second frame components 110, 120 may be isolated to the frame component to which the force is acted on.
As shown, the conduit portion 130 is arranged between the first frame component and the second frame component. At least a portion of the conduit portion 130 is generally radially or circumferentially unsupported by the first and second frame components 110, 120 within the conduit portion 130. As shown in
In certain instances, the first and second frame components 110, 120 may impart tension to the conduit portion 130 to deploy and maintain the conduit portion 130 with a lumen therethrough. The conduit portion 130 may be deployed within the septum between tissue surfaces through an opening (e.g., needle stick across the septum) that has a diameter smaller than a fully deployed diameter of the conduit portion 130. Tension in the conduit portion 130 imparted by expansion of the first and second frame components 110, 120 may also expand the septum between tissue surfaces to a desired shunt size.
In certain instances, the conduit portion 130 may be substantially free of frame components. For example, because the first and second frame components 110, 120 are non-contiguous with one another, as described above, and are arranged external to the bounds of the conduit portion 130. The conduit portion 130 may include, for example, a membrane 132, such as an expanded polytetrafluoroethylene (ePTFE) membrane, connecting the first frame component 110 and the second frame component 120. The membrane 132 generally separates the first frame component 110 and the second frame component 120 by a suitable distance compatible with the patient’s body. For example, the membrane 132 can separate the first frame component 110 and the second frame com ponent 120 by a gap of from 0 to 15 mm depending on the desired treatment location within the patient’s body. In addition, the conduit portion may be formed of only the membrane 132. The conduit portion 130, which is configured to be deployed within the septum between tissue surfaces, is free of the first frame component 110 and the second frame com ponent 120. The conduit portion 130 may include a smooth interior that facilitates blood flow therethrough without ridges from a stent element interrupting or disrupting flow. Thus, the conduit portion 130 may lessen the opportunity for thrombosis.
In addition to the membrane 132 forming the conduit portion 130, the membrane 132 may also cover at least a portion of the first frame component 110, at least a portion of the second frame component 120, or at least a portion of the first frame component 110 and the second frame component 120. In certain instances, the mem brane 132 arranged on at least a portion of the first frame com ponent 110 and/or the second frame component 120 is a separate membrane film (e.g., a first membrane film arranged on first frame component 110 and a second membrane film arranged on the second frame component 120). In these instances, the membrane film or films may be coupled to the membrane 132 in the conduit portion 130. The membrane 132 may be elastic to allow for expansion of the conduit portion 130 and to allow for movement of portions of the first frame component 110 and/or the second frame component 120 (e.g., movement of the first set of elongate elements 112 and/or the second set of elongate elements 122).
The membrane 132 may span gaps between the first set of elongate elements 112 and/or the second set of elongate elements 122. The membrane 132, in certain instances, is arranged on at least a tissue engaging side of the first frame component 110 and a tissue engaging side the second frame component 120. In these instances, the membrane 132 is configured to lessens frame erosion potential of the first frame com ponent 110 and/or the second frame component 120. The membrane 132 and the arrangement of the first set of elongate elements 112 and/or the second set of elongate elements 122 may conform to the tissue surfaces surrounding the septum. The first set of elongate elements 112 and/or the second set of elongate elements 122 may lay flat against the tissue surfaces.
In certain instances, each of the first set of elongate elements 112 may be attached to one another via the membrane 132 to form the first frame component 110. In certain instances, the first frame component 110 may form a substantially flat or 2-dimensional, disc-like shape, as shown. Additionally, or alternatively, the second set of elongate elements 122 may also be attached to one another via the membrane material 132 to form the second frame component 120. The second frame component 120 may also form a substantially flat or 2-dimensional, disc-like shape such that the first and second frame components 110, 120 are substantially parallel to one another when the device 100 is in a deployed configuration.
In certain instances, the membrane 132 may be configured to promote tissue ingrowth over at least a portion of the membrane 132, or at least a portion of the membrane 132. In certain instances, the membrane 132 is configured to promote tissue ingrowth to cover at least a portion of the first and/or second frame components 110, 120, which may further promote compatibility and stability of the device 100 within the patient’s body. The membrane 132 within the conduit portion 130 may be configured to not allow tissue ingrowth leading to increased patency. In certain instances, the membrane 132 is configured to promote endothelization without obstructive ingrowth within the conduit portion 130. The membrane 132 may promote endothelization without obstructive overgrowth of tissue into the conduit portion 130.
In certain instances, the device 100 may be capable of delivering a drug to the desired treatment location within the patient’s body. For example, the device 100 may be capable of eluting a drug configured to modulate tissue response. In certain instances, the device 100 may be coated with a therapeutic coating, drug eluting material or other therapeutic material or a hydrophilic coating. In one specific example, the device 100 can be coated with heparin to facilitate thromboresistance and patency of the device 100. Alternatively, or additionally, the device 100 may include paclitaxel (to modulate tissue/cellular response).
In certain instances, one of the first or second set of elongate elements 112, 122 of the first and second frame components 110, 120 may be attached to one another via the membrane 132 while the other set of elongate elements are unattached (e.g., they are discrete and separate from adjacent elongate elements). In other instances, only some of the first or second set of elongate elements 112, 122 may be attached to one another, while other elongate elements of the first and second set of elongate elements 112, 122 are not attached. Thus, the device 100 can be highly customizable to the patient depending on the desired treatment location within the patient, and size and/or shape of the defect, among other factors.
The device 100 is generally deployable or expandable from a delivery configuration to the deployed configuration. In some instances, the first set of elongate elements 112 and the second set of elongate elements 122 may nest within one another when the device is in the delivery configuration. This allows the device 100 to compress to a smaller size, for example, for delivery of the device 100 to a wider variety of treatment locations (e.g., through small, narrow, or convoluted passageways).
In certain instances, the first and second elongate elements 112, 122 are configured to separate from one another when the device 100 is in the deployed configuration. As shown in
The first and second frame components 110, 120 may maintain a lumen through the conduit portion 130 and facilitate deployment of the conduit portion 130 by laterally forcing the conduit portion 130 open. In addition, the lumen may be free or without the first and second frame components 110, 120. In this manner, the conduit portion 130 may facilitate re-crossing of the septum for addition procedures (e.g., left atrial appendage occluder implantation). In addition, the first and second frame components 110, 120 may be differently configured. For example, one of the first and second frame components 110, 120 may be flared while the other of the first and second frame components 110, 120 is flat. In other instances, both the first and second frame components 110, 120 may be flared. In addition, one of the first and second frame components 110, 120 may be convex while the other of the first and second frame components 110, 120 is flat or concave or both the first and second frame components 110, 120 may be convex. Further, one of the first and second frame components 110, 120 may be concave while the other of the first and second frame com ponents 110, 120 is flat or convex or both the first and second frame components 110, 120 may be concave. In addition, the first and second frame components 110, 120 may be different sizes.
The first and second frame components 110, 120 may include a sensor integrated into the respective frame component, for example, for continuous monitoring of various hemodynamic parameters such as pressure, among other parameters, within the patient’s body. For example, an antenna or inductor may be wrapped around the perimeter of one of the first and second frame components 110, 120 and the sensor may be attached to the inductor. The sensor may be configured to, for example, sense physiologic properties, such as temperature, electrical signals of the heart, blood chemistry, blood pH level, hemodynamics, biomarkers, sound, pressure, and electrolytes that may be important in diagnosing, monitoring, and/or treating heart disease, heart failure, and/or other cardiovascular disease states
In certain instances, the conduit portion 130 may be sizeable after delivery. The membrane 132 may be selectively adjustable by a balloon applied within the conduit portion 130 to distend the membrane 132. The device 100 can be any size suitable to fit the anatomy of the patient. In certain instances, a diameter of the conduit portion is from 3 to 12 mm. For example, the diameter of the conduit portion may be from 4 to 10 mm, or from 5 to 8 mm depending on the anatomy of the patient and/or the desired treatment location. The first and second frame components 110, 120 generally have a larger diameter than that of the conduit portion 130, for example, so that the frame components may anchor the conduit portion 130 of the device 100 within the septum.
The device 100 can be any shape suitable to fit the anatomy of the patient. For example, the first and second frame portions 110, 120 may be any of a variety of suitable shapes for anchoring the device 100 within the patient’s body. For example, the first and second frame portions 110, 120 may be substantially circular, ovular, diamond-shaped, star-shaped, flower-shaped, or any other suitable shape as desired. In certain instances, for example, at least one of the first and second set of elongate elements 112, 122 form a star shape. In certain instances, both the first and second set of elongate elements 112, 122 form a star shape.
In certain instances, the first set of elongate elements 112 forms a plurality of first lobes 116 and the second set of elongate elements 122 forms a plurality of second lobes 126. Each of the plurality of first and second lobes 116, 126 may include, for example, from 3 to 12 lobes, from 4 to 10 lobes, or from 6 to 8 lobes as desired. In certain instances, the plurality of first lobes 116 may have more lobes than the plurality of second lobes 126, while in other instances, the plurality of first lobes 116 may have the same number of lobes or less lobes than the plurality of second lobes 126.
The membrane may span gaps between the elongate elements 112, and, in certain instances, may be arranged on at least a tissue engaging side of the frame component 400. In these instances, the membrane is configured to lessens frame erosion potential of the frame component 400. The elongate elements 112 may conform to the tissue surfaces surrounding the septum. In addition, the elongate elements 112 may lay flat against the tissue surfaces.
In certain instances, the elongate elements 112 form a star shape as is shown in
The membrane may span gaps between the elongate elements 112, and, in certain instances, may be arranged on at least a tissue engaging side of the frame component 500.

In addition, the elongate elements 112 may lay flat against the tissue surfaces.
In certain instances, the elongate elements 112 form a star shape as is shown in
The membrane may span gaps between the elongate elements 112, and, in certain instances, may be arranged on at least a tissue engaging side of the frame component 600. In these instances, the membrane is configured to lessens frame erosion potential of the frame com ponent 600. The elongate elements 112 may conform to the tissue surfaces surrounding the septum. In addition, the elongate elements 112 may lay flat against the tissue surfaces.
In certain instances, the elongate elements 112 form a star shape as is shown in
The membrane may span gaps between the elongate elements 112, and, in certain instances, may be arranged on at least a tissue engaging side of the frame component 700. In these instances, the membrane is configured to lessens frame erosion potential of the frame component 700. The elongate elements 112 may conform to the tissue surfaces surrounding the septum. In addition, the elongate elements 112 may lay flat against the tissue surfaces.
