Abstract
Description
[0001] Cross-reference to related applications
[0002] This application claims the benefit of U.S. Patent Application No. 63 / 587,408, filed October 2, 2023, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field
[0003] This application relates to various aspects of textile materials that can be used in implantable medical devices. More specifically, this application relates to woven, one-piece textile materials used as cushioning materials in implantable devices. Background Technology
[0004] The heart can suffer from various valvular diseases or malformations, leading to significant cardiac dysfunction and ultimately requiring the replacement of natural heart valves with artificial ones. The human heart valves, including the aortic, pulmonary, mitral, and tricuspid valves, function essentially like one-way valves that work in sync with the pumping heart. Valves allow blood to flow downstream but prevent it from flowing upstream. Diseased heart valves exhibit damage such as valvular stenosis or regurgitation, which inhibits the valve's ability to control blood flow. Such damage reduces the heart's pumping efficiency and can lead to debilitating and life-threatening conditions. For example, valvular insufficiency can cause conditions such as cardiac hypertrophy and ventricular dilatation. Therefore, considerable effort has been made to develop methods and devices to repair or replace damaged heart valves.
[0005] Prostheses exist to correct problems associated with damaged heart valves. For example, mechanical and tissue-based heart valve prostheses can be used to replace damaged autologous heart valves. Recently, significant efforts have been devoted to developing replacement heart valves, particularly tissue-based replacement heart valves, which can be delivered with less trauma to the patient than through open-heart surgery. Replacement valves are designed for delivery via minimally invasive surgery and even percutaneous procedures. Such replacement valves typically consist of a tissue-based valve body connected to an expandable frame, which is then delivered to the annulus of the natural valve.
[0006] These replacement valves are typically designed to at least partially stop blood flow. However, problems arise when blood flows around the valve on the outside of the prosthesis. For example, addressing paravalvular leakage has proven particularly challenging in the case of heart valve replacement. Additional challenges involve the ability of such prostheses to be secured relative to intraluminal tissue (e.g., any tissue within a lumen or body cavity) in a way that prevents injury. Further challenges arise when attempting to deliver and secure such prostheses in a controlled manner at locations such as the natural mitral valve. These replacement valves are typically designed to at least partially stop blood flow.
[0007] Due to the drawbacks associated with conventional open-heart surgery, percutaneous and minimally invasive surgical approaches have garnered significant attention. In one technique, prosthetic valves are configured for implantation via catheter insertion, a procedure that is far less invasive. For example, U.S. Patents 10,716,664, 9,681,951, 10,583,000, and 11,224,507, and International Patent Publications WO2018017886 and WO2019 / 169087 (the entire contents of which are incorporated herein by reference for all purposes) describe heart valve prostheses for replacing natural valves, comprising a self-expanding frame with multiple anchoring members designed to be deployed within the body cavity and to prevent axial flow of fluid around the prosthesis.
[0008] However, problems still arise. For example, some challenges involve the ability to secure the prosthesis relative to intraluminal tissue (e.g., any tissue within a lumen or body cavity) in a way that prevents damage. Further challenges arise when attempting to deliver and secure such a prosthesis in a controlled manner in a particular location.

[0044] This disclosure can be more readily understood by referring to the following detailed description, examples, drawings, and claims, as well as the description preceding and following them. However, before disclosing and describing the articles, systems, and / or methods of this disclosure, it should be understood that, unless otherwise stated, this disclosure is not limited to the specific or exemplary aspects of the disclosed articles, systems, and / or methods, and therefore variations are naturally possible. It should also be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.
[0045] The following description of this disclosure is provided as a teaching on what can be achieved in its best, currently known aspects. Therefore, those skilled in the art will recognize and understand that many changes can be made to various aspects of this disclosure as described herein, while still obtaining the beneficial results of this disclosure. It will also be apparent that some of the desired benefits of this disclosure can be obtained by selecting some features of this disclosure without utilizing others. Therefore, those skilled in the art will recognize that many modifications and changes to this disclosure are possible, and in some cases even desirable, and are part of this disclosure. Thus, the following description is again provided as an illustration of the principles of this disclosure, and not as a limitation thereof.
[0046] definition
[0047] As used in this application and claims, the singular forms “a,” “an,” and “the” include the plural forms unless the context clearly specifies otherwise. Thus, for example, unless the context clearly specifies otherwise, reference to “yarn” includes aspects having two or more such yarns.
[0048] It should also be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting. As used in the specification and claims, the term "comprising" may include aspects that are "composed of" and "substantially composed of". Additionally, the term "include" means "comprise".
[0049] The terms “for example,” “exemplary,” and “such as,” and their grammatical equivalents, unless otherwise expressly stated, shall be understood to follow the phrase “but not limited to.”
[0050] A range may be expressed herein as from “about” one specific value and / or to “about” another specific value. When such a range is expressed, the other side includes from one specific value and / or to another specific value. Similarly, when a numerical value is expressed as an approximation using the antecedent “about”, it will be understood that the specific value constitutes the other side. It should also be understood that the endpoints of each range are significant both relative to and independent of the other endpoint. Unless otherwise stated, the term “about” means within 5% (e.g., within 2% or 1%) of the specific value modified by the term “about”. It should also be understood that if the term “about 1” is disclosed, the term “1” is also disclosed.
[0051] Throughout this disclosure, various aspects of this disclosure may be presented in the form of ranges. It should be understood that the description in range form is merely for convenience and brevity and should not be construed as an immutable limitation on the scope of this disclosure. Therefore, the description of a range should be considered as having specifically disclosed all possible subranges and individual numerical values within that range. For example, a description of a range such as from 1 to 6 should be considered as having specifically disclosed subranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and individual numbers within that range, such as 1, 2, 2.7, 3, 4, 5, 5.3, 6, and any integers and partial increments between them. This applies regardless of the width of the range.
[0052] As used herein, the terms “optional” or “optionally” mean that an event or situation described below may or may not occur, and the description includes instances where the event or situation occurs and instances where it does not occur.
[0053] Furthermore, the terms “link” and “association” generally mean an electrical, electromagnetic, and / or physical (e.g., mechanical or chemical) connection or link, and do not exclude the existence of intermediate elements between the linked or associated items.
[0054] It should be understood that when an element is referred to as “connected” or “linked” to another element, it may be directly connected or linked to the other element, or there may be intermediate elements. Conversely, when an element is referred to as “directly connected” or “directly linked” to another element, there are no intermediate elements. Other terms used to describe relationships between elements or layers should be interpreted in a similar manner (e.g., “between” vs. “directly between”, “adjacent” vs. “directly adjacent”, “on” vs. “directly above”).
[0055] It should be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, without departing from the teachings of the examples, the first element, component, region, layer, or part discussed below may be referred to as the second element, component, region, layer, or part.
[0056] For ease of description, this document uses spatial relative terms such as “below,” “under,” “lower,” “above,” “upper,” “upward,” “downward,” “top,” “bottom,” etc., to describe the relationship of one element or feature to another, as shown in the figures. It will be understood that, in addition to the orientation depicted in the figures, the spatial relative terms are also intended to cover different orientations of the device during use or operation. For example, if the device in the figures is flipped, an element described as “below” or “under” other elements or features will be oriented “above” other elements or features. Thus, the term “below” can encompass both upward and downward orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein will be interpreted accordingly.
[0057] Terms such as “proximal,” “farthest,” “radial outward,” “radial inward,” “external,” “internal,” and “side” describe the orientation and / or position of parts of a component or element within a consistent but arbitrary frame of reference, which becomes clear by referring to the text describing the component or element in question and the associated drawings. Such terms may include the words specifically mentioned above, their derivatives, and words with similar meanings. Similarly, unless the context clearly indicates otherwise, the terms “first,” “second,” and other such numerical terms referring to structures do not imply order or sequence.
[0058] As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It should also be understood that the term “and / or” includes situations where one or the other of the associated listed items is present, as well as aspects where two of the associated listed items are present or any combination of the associated listed items is present.
[0059] As used herein, the terms or phrases “effective,” “effective quantity,” or “condition effective for” refer to the quantity or condition that enables the realization of the function or property represented by the effective quantity or condition. As will be noted below, the exact quantity or specific condition required will vary depending on recognized variables, such as the materials used and the observed processing conditions. Therefore, it is not always possible to specify an exact “effective quantity” or “condition effective for”. However, it should be understood that a person skilled in the art can readily determine a suitable effective quantity using only routine experiments.
[0060] The terms "fiber" or "filament" are used interchangeably.
[0061] The terms “fiber” (or “filament”) and “material comprising multiple fibers (filaments)” are used herein in their broad and general sense and may refer to any type of natural or synthetic substance or material whose length is significantly greater than its width, including any elongated or relatively thin, elongated and / or filamentous sheets, filaments, ropes, yarns, ply yarns, strands, cords, cords, or portions thereof. Furthermore, “fiber” or “material comprising multiple fibers” may refer to a single filament or collectively to multiple filaments. Examples of materials comprising multiple fibers according to aspects of this disclosure include, but are not limited to, any type of cloth, fabric, or textile. It should be understood that, in some non-limiting aspects, the term “material comprising multiple fibers” may refer to cloth, fabric, textile, or interlocking fiber material that can cover or form certain features of the disclosed apparatus.
[0062] As used herein, the term "fiber" includes fibers of extreme or infinite length (e.g., filaments) and fibers of short length (e.g., staple fibers).
[0063] As used herein, the term “substantially” means that the events or circumstances subsequently described have occurred completely, or that the events or circumstances subsequently described are generally, usually, or substantially likely to occur.
[0064] Furthermore, in some respects, the term “substantially” may refer to at least about 90%, at least about 91%, at least about 92%, at least about 93%, at least about 94%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or about 100% of the said property, component, composition, or other condition, wherein “substantially” is used to characterize or otherwise quantify the quantity.
[0065] As used herein, the term “substantially”, such as in the context of “substantially identical” or “substantially similar”, means a method, system or component that is at least about 90%, at least about 91%, at least about 92%, at least about 93%, at least about 94%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or about 100% similar to the method, system or component being compared.
[0066] As disclosed herein, it should be understood that when referring to the thickness of an indicated component, the thickness referred to is the thickness of the component wall.
[0067] While the operations of exemplary aspects of the disclosed methods may be described in a specific order for ease of presentation, it should be understood that the disclosed aspects may encompass an order of operations other than the specific order disclosed. For example, in some cases, the operations described in the order may be rearranged or performed simultaneously. Furthermore, the descriptions and disclosures provided in association with a particular aspect are not limited to that aspect and may be applied to any aspect disclosed.
[0068] Furthermore, for simplicity, the accompanying drawings do not illustrate the various ways in which the disclosed systems, methods, and apparatus can be combined with other systems, methods, and apparatuses (which will be readily apparent to those skilled in the art based on this disclosure). Additionally, this specification sometimes uses terms such as “produce” and “provide” to describe the disclosed methods. These terms are high-level abstractions of actual, executable operations. The actual operations corresponding to these terms may vary depending on the specific implementation and will be readily apparent to those skilled in the art based on this disclosure.
[0069] woven products
[0070] The woven articles disclosed herein are 3D monolithic articles in which the components (or parts) are constructed together during the weaving process. It should be understood that, depending on the intended application, the articles may include any or some of the components disclosed herein. Figure 3 An exemplary woven 3D monolithic article is shown.
[0071] This document discloses a braided article defined by a proximal end 3100 and a distal end 3200. In some aspects, the disclosed braided article 3000 includes a tubular member 3002 having a lumen 3001 disposed between a first open end 3003 and a second end 3005 of the tubular member 3002. In some aspects, the first open end 3003 defines the proximal end 3100 of the braided article. In some aspects, the tubular member has a first thickness. In some other aspects, the lumen has a diameter d1 and a length l1.
[0072] In another aspect, the woven article 3000 further includes a cushioning member 3007 having a second thickness, wherein the outer surface of the tubular member seamlessly transitions to the outer surface of the cushioning member at a length l2 from the first open end of the tubular member, thereby forming a proximal end 3009 of the cushioning member, wherein l2 is less than l1. In another aspect, a portion of the cushioning member includes a central cavity 3011 that receives a portion 3004 of the tubular member having a length l3, such that a second end 3005 of the tubular member is positioned within the central cavity of the cushioning member. It is understood that the length l3 is equal to l1 ≈ l2. In the aspects disclosed herein, the outer surface of the cushioning member is formed by transitioning the outer surface of the tubular member, while the inner surface of the cushioning member defines at least a portion of the central cavity of the cushioning member.
[0073] In the aspects disclosed herein, the first thickness of the tubular member can be from about 0.06 mm to about 0.15 mm, including exemplary values of about 0.07 mm, about 0.08 mm, about 0.09 mm, about 0.1 mm, about 0.11 mm, about 0.12 mm, about 0.13 mm, and about 0.14 mm. In another aspect, the first thickness can have any value falling between any two of the foregoing values, or can fall within a range formed by any two of the foregoing values. For example, but not limited to, the first thickness can be about 0.06 mm to about 0.14 mm, about 0.06 mm to about 0.13 mm, about 0.06 mm to about 0.12 mm, about 0.06 mm to about 0.11 mm, about 0.06 mm to about 0.10 mm, about 0.06 mm to about 0.09 mm, about 0.06 mm to about 0.08 mm, about 0.08 mm to about 0.15 mm, about 0.10 mm to about 0.15 mm, about 0.12 mm to about 0.15 mm, and so on.
[0074] In some respects, the first thickness may be uniform along length l1. In other respects, the first thickness may be uniform along some portions of the tubular member, while gradually varying along other portions. For example, but not limited to, the thickness along l2 may be the same as, but different from, the thickness along l3. In another exemplary respect, the thickness along l3 may be uniform, or it may vary gradually along l3. In another respect, the thickness may vary along l2 and / or l3 in any desired pattern. It should also be understood that the thickness may vary circumferentially as well as along the longitudinal axis. For example, it should be understood that the first thickness may, but does not necessarily, be uniform along the circumference of the tubular member. In another respect, the first thickness (or any thickness disclosed herein) may be thicker at the surface of the article adjacent to the natural anatomical structure when compared to the surface of the article further away from the natural anatomical structure.
[0075] In some aspects, l2 is greater than or equal to about 10 mm to about 16 mm, including exemplary values of about 10.5 mm, about 11 mm, about 11.5 mm, about 12 mm, about 12.5 mm, about 13 mm, about 13.5 mm, about 14 mm, about 14.5 mm, about 15 mm, and about 15.5 mm. In other aspects, l3 is about 2.5 mm to about 6 mm, including exemplary values of about 3 mm, about 3.5 mm, about 4 mm, about 4.5 mm, about 5 mm, and about 5.5 mm. In still other aspects, l2 may have any value falling between any two of the foregoing values, or may fall within a range formed by any two of the foregoing values. For example, but not limited to, l2 can be about 10 mm to about 15 mm, about 10 mm to about 14 mm, about 10 mm to about 13 mm, about 10 mm to about 12 mm, about 10 mm to about 11 mm, about 11 mm to about 16 mm, about 12 mm to about 16 mm, about 14 mm to about 16 mm, and so on.
[0076] In another aspect, the diameter d1 of the tubular member can be the same or different along the length l1. In another aspect, d1 can be the same along l2, for example, as... Figure 3 As shown. In another aspect, d1 can gradually change along l2 (not shown). In another aspect, the diameter d1 can change along l2 to d1', d1''. 和 / or d1'''. It should be understood that in some respects, d1' is the same as d1'' and / or d1'''. In other respects, d1', d1'', and / or d1''' are all different depending on the intended application.
[0077] In another aspect, d1', d1'', and / or d1''' may have values from about 2 mm to about 4 mm, including exemplary values of about 2.1 mm, about 2.2 mm, about 2.3 mm, about 2.4 mm, about 2.5 mm, about 2.6 mm, about 2.7 mm, about 2.8 mm, about 2.9 mm, about 3 mm, about 3.1 mm, about 3.2 mm, about 3.3 mm, about 3.4 mm, about 3.5 mm, about 3.6 mm, about 3.7 mm, about 3.8 mm, and about 3.9 mm. In another aspect, d1', d1'', and / or d1''' may have any value falling between any two of the foregoing values, or may fall within a range formed by any two of the foregoing values. For example, but not limited to, d1', d1" and / or d1"' can be about 2mm to about 3.7mm, about 2mm to about 3.5mm, about 2mm to about 3.3mm, about 2mm to about 3mm, about 2mm to about 2.7mm, about 2mm to about 2.5mm, about 2.2mm to about 4mm, about 2.5mm to about 4mm, about 2.7mm to about 4mm, about 3mm to about 4mm, about 3.2mm to about 4mm, about 3.5mm to about 4mm, and so on.
[0078] In another aspect, the woven article may also include a woven seal 3012 positioned at the distal end 3019 of the cushioning member 3007.
[0079] In another respect, each component of the disclosed article may have one or more layers, if required.
[0080] In other aspects, the cushioning member 3007 can have any desired shape. In some aspects, the cushioning member can have a regular or irregular shape. For example, the cushioning member can be spherical, cubic, cuboid, pyramidal, oval, conical, or prism-shaped. In other aspects, the cushioning member 3007 can have a regular or irregular cross-sectional shape. The cross-sectional shape of the cushioning member can be circular, oval, elliptical, rectangular, square, or any combination thereof. In some aspects, the cushioning member is symmetrical. In other aspects, the cushioning member is asymmetrical. It should also be understood that because the cushioning member is made of textile material, its shape is not rigid and can deviate from its original shape during use.
[0081] In another aspect, the cross-sectional shape is defined by a length a1 along at least one of the x-axis or y-axis. For example, as Figure 3As shown, the buffer member may have a length a1 along the x-axis. In such exemplary and non-limiting aspects, the length a1 is the maximum length defining the cross-sectional shape. It should be understood that in some aspects, the length along the y-axis may also be a1. In other aspects, the length along the y-axis may be a1', which is different from a1.

[0102] Figure 10 The diagram illustrates an exemplary and non-limiting aspect of a honeycomb pattern representing a planar representation 10 of a cushioning material. In this example, the honeycomb weave pattern may include a repeating pattern of channels 12. Channels 12 may have portions of different heights, with the central portion 14 (in...) Figure 11 (represented in the middle) has a larger outer portion than 16 (in the middle) Figure 11 (The text indicates a lower height.) The central portion 14 can form a recess surrounded by the outer portion 16. The outer portion 16 can include raised walls surrounding the recess of the central portion 14. Each channel 12 can include a recess surrounded by walls. In some aspects, the recess can have various shapes, including an inverted pyramid shape, a dome shape, or another shape as required. The channel 12 can have a square or rectangular shape, such as... Figures 10 to 11 As shown, it can also have another shape as needed.
[0103] The channel 12 can repeat along the length 18 and width 20 of the plane of the cushioning material 10. It should be understood that, since the cushioning material described herein has a 3-D shape, the channel 12 can repeat along all perimeters of the cushioning material. The channels 12 can be adjacent to each other, wherein the outer portion 16 of each channel 12 is adjacent to the outer portion 16 of the adjacent channel, for example, as... Figure 11 As shown. Figure 10 and Figure 11 As shown, in the example, the channels can be aligned with each other along length 18 (by column) and width 20 (by row), or other patterns can be used as needed. For example, in the example, channels 12 can be aligned diagonally or on another pattern as needed. Channels 12 can repeat in an irregular configuration; for example, a channel 12 can have a square configuration, such as... Figure 11 As shown, and in the example, adjacent channels may have a different configuration.
[0104] In another aspect, the honeycomb weave pattern can be formed by warp and weft threads, which interweave and float in a manner that produces an outer portion 16 (e.g., walls) and a central portion 14 (e.g., recesses) of a regular pattern. In some aspects, warp and weft floats can be arranged around the center of the plain weave and can be partially woven on a plain weave area surrounded by ridges of long floats. Other configurations can be utilized as needed.
[0105] However, it should be understood that other weaving configurations can also be used. For example, in some aspects, four-end cell repeats to thirty-two-end cell repeats can be used. In some aspects, configurations larger than thirty-two-end cell repeats can be used. In some aspects, a range between four-end cell repeats and sixteen-end cell repeats can be used. In some aspects, a range between sixteen-end cell repeats and thirty-two-end cell repeats can be used. Other configurations can be used as needed.
[0106] In some respects, honeycomb weave patterns may include honeycomb weave derivative weave patterns, such as improved honeycomb weave patterns or other derivative weave patterns as required.

[0108] In some respects, the repeating pattern of the channels 12 is visible, including a recess in the central portion 14 surrounded by the walls of the outer portion 16 for each channel 12. The variation in height between the recess in the central portion 14 and the walls of the outer portion 16 is visible.

[0110] In another aspect, the first thickness of the tubular member is less than the second thickness of the cushioning member. In another aspect, the second thickness is the same or different along the circumference and / or periphery and / or along the length of the cushioning member.
[0111] As disclosed above, yarns used to construct the articles disclosed herein can exhibit heat shrinkage when heated at a desired temperature for a desired time. Examples of this heat shrinkage are... Figures 12A to 12B As shown in the image. For example, Figure 12A A portion of the surface of the buffer member 10 prior to heat treatment is illustrated. The length 17 and width 19 of the exemplary channel unit 12 are marked. Figure 12B Examples are given after heat treatment. Figure 12A A portion of the surface of the buffer member 10 shown, wherein the length 17 and width 19 of the channel unit 12 have been reduced, while the second thickness of the buffer member has been increased.
[0112] In another aspect, a buffer gradient can be achieved by changing the weave density, the number of repeating channel units, the number of weft insertions in multiple weft yarns, the denier of the weft yarns, the weft texture, or a combination thereof. A buffer gradient can be achieved by changing the number of repeating channel units within the buffer member. For example, as discussed above, the number of repeating channel units can vary from about 1 channel / inch to about 32 channel / inch, including repeating units with values of about 2 channel / inch, about 5 channel / inch, about 8 channel / inch, about 10 channel / inch, about 12 channel / inch, about 15 channel / inch, about 18 channel / inch, about 20 channel / inch, about 22 channel / inch, about 25 channel / inch, about 28 channel / inch, and about 30 channel / inch. The number of channels per inch can fall between any two of the aforementioned values or within any range formed by any two of the aforementioned values. For example, but not limited to, about 1 channel / inch to about 30 channels / inch, about 1 to about 28 channels / inch, about 1 to about 24 channels / inch, about 1 to about 20 channels / inch, about 1 to about 16 channels / inch, about 1 to about 10 channels / inch, about 5 to about 32 channels / inch, about 8 to about 32 channels / inch, about 10 to about 32 channels / inch, about 12 to about 32 channels / inch, about 16 to about 32 channels / inch, and so on.
[0113] By varying the weft insertion amount as discussed above, a buffer gradient can be further achieved within the buffer member, from approximately 8 weft insertion repeats / linear inches to approximately 50 weft insertion repeats / linear inches, including exemplary values of approximately 10 weft insertion repeats / linear inches, approximately 12 weft insertion repeats / linear inches, approximately 15 weft insertion repeats / linear inches, approximately 18 weft insertion repeats / linear inches, approximately 20 weft insertion repeats / linear inches, approximately 22 weft insertion repeats / linear inches, approximately 25 weft insertion repeats / linear inches, approximately 28 weft insertion repeats / linear inches, approximately 30 weft insertion repeats / linear inches, approximately 32 weft insertion repeats / linear inches, approximately 35 weft insertion repeats / linear inches, approximately 38 weft insertion repeats / linear inches, approximately 40 weft insertion repeats / linear inches, approximately 42 weft insertion repeats / linear inches, approximately 45 weft insertion repeats / linear inches, and approximately 48 weft insertion repeats / linear inches. It should be understood that the buffer member may have any number of weft insertion repetitions per linear inch falling between any two of the aforementioned values or within the range formed by any two of the aforementioned values.
[0114] A buffer gradient can also be achieved by varying the weft yarn denier from about 10 denier to about 200 denier, including exemplary values of about 20 denier, about 50 denier, about 70 denier, about 100 denier, about 120 denier, about 150 denier, and about 170 denier. It should be understood that the weft yarn denier can have any value falling between any two of the foregoing values or within the range formed by any two of the foregoing values. For example, the weft yarn denier can be about 10 to about 150 denier, about 10 to about 100 denier, about 10 to about 70 denier, about 10 to about 50 denier, about 50 to about 200 denier, about 70 to about 200 denier, about 100 to about 200 denier, about 150 to about 200 denier, and so on. Furthermore, a buffer gradient can be achieved by changing the weft yarn from undeformed (flat or FDY yarn) to a highly deformed yarn.

[0148] It should be understood that any of the products described above can be used in implantable medical devices.
[0149] In some aspects, an exemplary implantable medical device may include a frame 1000, such as Figure 1As shown. In this respect, frame 1000 is shown in an expanded configuration. Frame 1000 may include a frame portion 1002 having an upper region 1004, a middle region 1006, and a lower region 1008. In some aspects, when frame 1000 is in the expanded configuration, the middle region 1006 may have a larger diameter than the diameter of frame 1000 at its proximal (adjacent to the upper region) and / or distal (adjacent to the lower region) ends. In some aspects, such as the illustrated aspect, frame 1000 may include a middle region 1006 that, when frame 1000 is in the expanded configuration, has a larger cross-sectional area than the cross-sectional area of frame 1000 at its proximal end (against the upper region) and / or distal end (against the lower region). The longitudinal axis (not shown) of frame 1000 may be defined as a central axis extending between the upper and lower ends of frame 1000 and passing through the center of frame 1000. In some aspects, the frame 1000 may be oriented such that the upper region 1004 is a proximal portion and the lower region 1008 is a distal portion. The frame 1000 may include a plurality of anchoring members 1010. In some aspects, the frame 1000 may be oriented such that the plurality of anchoring members 1010 are distal anchoring members. As shown in the illustrated aspects, the plurality of anchoring members 1010 may include one or more anchors. For example, but not limited to, as shown in the illustrated aspects, the plurality of anchoring members 1010 may include nine anchors, each anchor including a neck 1012 and an arm 1013 extending from the lower region 1008 of the frame portion 1002, and a tip 1014. However, it should be understood that the implantable device may have more than nine anchors or fewer than nine anchors. For example, the device may have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 anchors. Figure 1 As shown, in some aspects, each of the one or more anchors has a hook shape.

Figure 2A and Figure 2B The anchor 2010 shown is positioned within the woven article disclosed herein. The anchor may be defined by a neck 2012, an arm 2013, and a tip 2014 (or head).
[0154] In another aspect, implantable medical devices are configured to be deployed onto a natural valve of the heart, wherein the prosthetic valve also includes multiple prosthetic leaflets as shown herein, wherein one or more anchors are attached to the multiple prosthetic leaflets, and each anchor is configured to be anchored to a portion of the heart.
[0155] Figure 7 An exemplary anchor enclosed within the article disclosed herein is shown. It can be seen that the anchor 7000 has a hook shape. Furthermore, the anchor includes a radially inward-facing surface 59 and a radially outward-facing surface 61. The anchor has a neck 7012, an arm 7013, and a head or tip 7014. The anchor is inserted into the braided article 6000 and positioned within the lumen 6003 of the tubular member, such that the cushioning member 6006 is positioned around the tip 7014. A cover member 6010 folds over portions of the cushioning member and the tubular member 6004. It should be understood that the edge 7015 of the cover member seals with the rest of the braided article after its folding. It should be understood that such sealing can be achieved by any method known in the art, such as sewing, laser welding, ultrasonic welding, etc.
[0156] In some aspects, each of one or more anchors is configured to hook around the natural valve leaflet with its surface radially inward toward the natural valve leaflet, and wherein a second thickness of a buffer member disposed on the inner surface of the anchor is greater than a second thickness of a buffer member disposed on the outer surface of the anchor.
[0157] As detailed herein, implantable medical devices may also include sealing elements or outer skirts (2018). Figure 2A The outer skirt or sealing element can be used for periploidal leak sealing.
[0158] In such exemplary and non-limiting aspects, a portion of the sealing element may include a fabric having a 3-D honeycomb pattern. In such aspects, the textile may include a weave pattern substantially identical to that of the cushioning member. In another aspect, the textile may include multiple weft yarns and / or multiple warp yarns substantially identical to those of the cushioning member. For example, as... Figure 2AAs shown, a portion of the sealing element may extend circumferentially between adjacent anchors of the plurality of anchors. In another aspect, a portion of the sealing element may be positioned relative to each of the plurality of anchors.
[0159] Additional examples of implantable medical devices are in Figure 8A and Figure 8B As shown in the image. Figure 8A and Figure 8B An example of a prosthetic valve 40 that can be used with the systems, devices, and methods disclosed herein is illustrated. The prosthetic valve 40 includes a prosthetic heart valve and can be configured to be deployed into the heart as a natural valve. The prosthetic valve 40 may include a distal anchor 42 and a plurality of prosthetic valve leaflets 44 (in... Figure 8B (Seen more clearly in the top view). The prosthetic valve 40 may include a valve body 41 that can support a plurality of prosthetic valve leaflets 44. In some aspects, the valve body 41 may include an outer skirt 46 (or an inner skirt, not shown) and may include one or more frames.
[0160] The outer skirt 46 surrounds the outer surface of the valve body 41 and contacts a portion of the autologous heart valve (such as an autologous heart valve leaflet) to seal with these portions. The frame 49 of the valve body 41 (in...) Figure 8B The center marker (indicated by the outer frame) can support multiple artificial valve leaflets 44. In this exemplary aspect, the frame 49 may include an inner frame that can be positioned on the outer frame 47 (in the outer frame). Figure 8A The radial inner side of the inner frame 49 (marked in the middle). In this respect, the outer frame 47 may surround the inner frame 49.
[0161] The outer frame 47 may include a portion of the sealing body, which may include an outer skirt 46 for sealing with a portion of the natural heart valve. The outer skirt 46 may reduce the likelihood of leakage outside the flow passage of the prosthetic valve (e.g., paravalvular leakage). It should be understood that the valve shown herein is merely exemplary, and other configurations of the frame or valve body may be considered.
[0162] The implantable medical device may also include struts 48 forming a frame 49 of the prosthetic valve 40, and the outer frame 47 may also include struts. Some of the struts 48 may terminate at end tab portions 50, which are configured to be coupled to a part of a delivery device. For example, the end tab portions 50 may be configured to engage a coupling 52 of the delivery device (as in...). Figure 14A and Figure 14B (marked in the middle) to attach the prosthetic valve 40 to the delivery device. The end tab portion 50 may, if necessary, include an open semi-dome shape or another shape to attach to the connector 52. Figure 8B A top view of the prosthetic valve 40 is shown.
[0163] The valve body 41 can surround the flow channel 45 (in Figure 8A (marked in the middle), the central axis of the prosthetic valve 40 can extend along the flow channel. The artificial valve leaflet 44 can extend radially inward from the valve body 41 toward the flow channel 45.
[0164] Multiple prosthetic valve leaflets 44 can be configured to open and close to replicate the operation of a natural valve. Figure 8A and Figure 8B In the example shown, the upper end 51 of the prosthetic valve 40 may include the inflow end of the prosthetic valve 40, and the lower end 53 of the prosthetic valve 40 may include the outflow end of the prosthetic valve 40. The prosthetic valve leaflet 44 can open and close to allow flow from the inflow end to the outflow end and to block flow from the outflow end to the inflow end.
[0165] Figure 8A and Figure 8B The prosthetic valve 40 shown is configured as a prosthetic mitral valve; however, other forms of implants may be used as needed. For example, prosthetic aortic valves, tricuspid valves, or pulmonary valves may be used with the systems, devices, and methods disclosed herein. Furthermore, other forms of implants, such as stents or other implants, may also be used with the systems, devices, and methods disclosed herein.
[0166] Figure 8A and Figure 8B The prosthetic valve 40 shown can be engaged with the ventricular side of a valve (such as a mitral or tricuspid valve) using a distal anchor 42. The distal anchor 42 may include a ventricular anchor positioned at the outflow end of the prosthetic valve 40. The distal anchor 42 may have a hook shape, allowing each distal anchor 42 to hook around the leaflet of the natural valve to secure the prosthetic valve 40 to the natural valve. Each anchor 42 may include an elongated arm of a certain length. In some aspects, the prosthetic valve 40 may also include a proximal anchor 55, which can engage the atrial side of the mitral valve, such as... Figure 16C and Figure 17 The anchors are marked in the middle. It should be understood that in some respects, such anchors 55 exist, while in others they are excluded. One or more anchors may be attached to multiple artificial valve leaflets 44, and each artificial valve leaflet is configured to be anchored to a part of the heart. Other forms of anchors may be used, as well as other forms of implants may be used in other respects.
[0167] Features of the implants that can be used are disclosed in U.S. Patent Application No. 16 / 028,172, the entire contents of which are incorporated herein by reference. Additional details and example designs of implants and prostheses that can be used in the examples herein are described in U.S. Patent Nos. 8,403,983, 8,414,644, 8,652,203 and U.S. Patent Publications Nos. 2011 / 0313515, 2012 / 0215303, 2014 / 0277390, 2014 / 0277422, 2014 / 0277427, 2018 / 0021129 and 2018 / 0055629, the entire contents of which are incorporated herein by reference for all purposes and are a part of this specification. Further details and examples of heart valve or prosthesis replacements and their implantation methods are described in U.S. Publication Nos. 2015 / 0328000 and 2016 / 0317301, the entire contents of which are incorporated herein by reference and form part of this specification.
[0168] The prosthetic valve 40 is compressible, allowing it to be compressed radially toward the longitudinal axis or central axis around which it surrounds. For example, the frame of the prosthetic valve 40 can be flexible to allow for compression. When compressed radially toward the longitudinal axis, the prosthetic valve 40 can longitudinally increase in length along the longitudinal axis (whereby the end flap portion 50 and the distal anchor 42 extend in opposite directions along the longitudinal axis, e.g., as...). Figure 14A (As shown). In some examples, the prosthetic valve 40 can be configured to compress in a radial direction toward the longitudinal axis without increasing the length of the prosthetic valve 40.
[0169] like Figure 8A and Figure 8B As shown, anchor 42 is inserted into the woven article disclosed herein, wherein the cushioning members of the article help cushion the anchor 42 against the natural structure of the patient's heart. Anchor 42 may, for example, include a rigid structure. In some aspects, anchor 42 may be coupled to frame 49 and integral with the struts 48 of frame 49. Similar to the anchors disclosed above, anchor 42 may include hook-shaped arms that are rigid and could potentially damage the natural structure of the patient's heart if they come into direct contact with it. The woven article disclosed herein covers anchor 42 to protect the natural structure from such contact.
[0170] Figure 9AThe steps of attaching the woven article 25 to the arm 56 of the anchor 42 are illustrated. The “cutout” of the article shown indicates that the arm 56 is positioned within the article. The neck 28 is positioned within the tubular part of the article, while the cushioning member 26 is positioned around the tip of the anchor. The cover member is shown before it is folded onto the cushioning member.
[0171] Figure 9B An exemplary assembly of a woven article on an anchor 42 on a frame 49 is shown. In this exemplary aspect, it can be seen that a cushioning member 37 covers the head of the anchor, and a tubular member 97 covers the arms and neck of the anchor. A covering member 99 is shown folded and then attached to the other parts of the woven article.
[0172] The woven fabric of this disclosure provides improved compressibility to cushion the anchor 42. This improved compressibility may be desirable compared to existing forms of liner that may include foam or another closed-cell material. The improved compressibility can further provide benefits during the deployment of the prosthetic valve 40.
[0173] For example, Figure 13 Aspects of a delivery device 60 are illustrated herein, which may be utilized and used to deploy implants such as prosthetic valve 40, according to the examples herein. Delivery device 60 may include an elongated shaft 62 having a proximal end coupled to a handle 64 and a distal end including an implant holding region 66 for the prosthetic valve 40, a nasal cone 68, and a sac-like member 70 extending over the implant holding region 66. The elongated shaft 62 may be deflectable to position the prosthetic valve 40 in a desired location relative to the implantation site. Features of the available delivery device and methods of deployment using the delivery device are disclosed in U.S. Patent Application No. 16 / 028,172, filed July 5, 2018, and published as U.S. Patent Publication No. 2019 / 0008640, the entire contents of which are incorporated herein by reference.
[0174] [For example, such as] Figure 14A As shown, the prosthetic valve 40 can be rolled into an elongated configuration within the sac-like element 70 prior to deployment. For clarity, in Figure 14A Only the frame 49 of the prosthetic valve 40 is shown. The distal anchor 42 is compressed and extends longitudinally along the longitudinal axis or central axis of the elongated axis 62. The compressive force of the sac 70 on the distal anchor 42 is preferably low to reduce the deployment force required to deploy the prosthetic valve 40 from the sac 70.
[0175] Figure 14B An example is a prosthetic valve 40 that is not present in the slender axis 62.
[0176] The deployment of the prosthetic valve 40 can occur in various forms, including surgical methods that involve access via the femoral artery or into the patient's heart. Figure 15 An exemplary procedure utilizing femoral access is illustrated. The elongated shaft 62 of the delivery device 60 may pass through the femoral vein, as well as other access points. Figure 15 An example is illustrated where the elongated shaft 62 of the delivery device 60 reaches the right atrium 71 via the femoral artery, and then the left atrium 72 of the patient's heart 74 via the septum. The elongated shaft 62 can be deflected to position the prosthetic valve 40 for deployment to the mitral valve. The elongated shaft 62 can be deflected toward the left ventricle 76.
[0177] Figures 16A to 16C The steps in the deployment of a prosthetic valve 40 are illustrated, wherein the sac-like element 70 is retracted relative to the prosthetic valve 40. The prosthetic valve 40 is deployed to the natural valve of the patient's heart. The prosthetic valve 40 extends out of an opening 80 in the sac-like element 70. Distal anchors 42 can extend distally and then deflect proximally to hook around the natural valve leaflet during deployment. Each of the distal anchors 42 can hook around the natural valve leaflet. The braided articles disclosed herein ( Figures 16A to 16C (Not shown in the image) The cushioning anchor 42 can be used during deployment, and the compressibility of the pad can reduce the deployment force of the prosthetic valve 40.
[0178] Figure 16B and Figure 16C An example is shown of a sac-like element 70 that is further retracted to deploy the prosthetic valve 40.
[0179] Figure 17 An example is shown of a prosthetic valve 40 deployed to a natural mitral valve, wherein a distal anchor 42 is hooked around the natural valve leaflet. In this example, the distal anchor 42 may be hooked around the natural valve leaflet and may be hooked around the chordae tendineae 82 if desired.
[0180] In some respects, other deployment methods can be utilized. For example, balloon-inflatable prosthetic valves can be used. Such valves can be positioned on the inflatable balloon upon entry into the patient's body, or can slide onto the inflatable balloon after entry into the patient's body. The inflatable balloon can be inflated with fluid to expand and deploy the prosthetic valve. Mechanically inflatable prosthetic valves, as well as self-expanding valves and other forms of deployment, can be further utilized.
