Abstract
A 3-D honeycomb textile can include a textured yarn. The textile can exhibit a heat-shrinkage rate from about 10% to about 60%. The textile can be configured to reversibly change its dimensions under application of stress. Prosthetic valves can have the disclosed textiles as a sealing member. Additionally, prosthetic valves can the disclosed textiles as cushion materials. In addition, methods of making the disclosed textiles and prosthetic valves are described.
Claims20
A textile comprising:
- a plurality of weft yarns and a plurality of warp yarns are arranged to form a 3-D honeycomb pattern having a plurality of repeating cell units, wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns is a textured yarn exhibiting a heat-shrinkage rate from about 10% to about 60%;
- wherein the textile has a first dimension in a relaxed position, and wherein the textile is configured to reversible arrive at a second dimension under application of stress, wherein the textile is bio-compatible.
An implantable medical device comprising:
- an annular frame having an inflow end, an outflow end, and a longitudinal axis;
- and a sealing element secured to the frame, wherein the sealing element comprises:
- a textile comprising a plurality of weft yarns and a plurality of warp yarns arranged to form a 3-D honeycomb pattern having a plurality of repeating cell units, wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns is a textured yarn exhibiting a heat-shrinkage rate from about 10% to about 60%;
- wherein the textile has a first dimension in a relaxed position, wherein the textile is configured to reversible arrive at a second dimension under application of stress, wherein the textile is bio-compatible;
- and wherein the implantable medical device is configured to radially collapse to a collapsed configuration and radially expand to an expanded configuration.
An implantable medical device comprising:
- a frame having an upper region, an intermediate region, and a lower region, wherein the frame is configured to radially expand and contract for deployment within a body cavity, and wherein the frame comprises a plurality of anchoring members disposed along the lower region;
- wherein at least a portion of at least some of the plurality of anchoring members is enclosed within a textile material comprising:
- a plurality of weft yarns and a plurality of warp yarns arranged to form a 3-D honeycomb pattern having a plurality of repeating cell units,
- wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns is a textured yarn exhibiting a heat-shrinkage rate from about 10% to about 60%;
- wherein the textile material is biocompatible and behaves as a cushion.
The implantable medical device of 13, wherein at least a portion of enclosures of at least a portion of at least some of the plurality of anchoring members is formed by two or more layers of the textile material.
An implantable medical device comprising:
- an annular frame having an inflow end, an outflow end, and a longitudinal axis;
- and a sealing element secured to the frame, wherein the sealing element comprises:
- a textile comprising a plurality of weft yarns and a plurality of warp yarns arranged to form a 3-D honeycomb pattern having a plurality of repeating cell units,
- wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns is a textured yarn exhibiting a heat-shrinkage rate from about 10% to about 60%;
- wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns further comprises a nontextured yarn, wherein the nontextured yarn and textured yarn have the same or different denier and/or the nontextured yarn and textured yarn have the same or different number of fibers;
- wherein the textile comprises a first edge and an opposite second edge, wherein at least a portion of the textile adjacent to the first and/or second edge comprises a plain weave, a twill weave, a satin weave, any derivation, or any combination thereof;
- wherein the textile has a first dimension in a relaxed position, wherein the textile is configured to reversible arrive at a second dimension under application of stress, wherein the textile is bio-compatible;
- and wherein the implantable medical device is configured to radially collapse to a collapsed configuration and radially expand to an expanded configuration.
A method comprising:
- weaving a plurality of weft yarns and a plurality of warp yarns to form a textile having a 3-D honeycomb pattern having a plurality of repeating cell units,
- wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns is a textured yarn exhibiting a heat-shrinkage rate from about 10% to about 60%;
- wherein at least one yarn of the plurality of warp yarns and/or the plurality of weft yarns further comprises a nontextured yarn, wherein the nontextured yarn and textured yarn have the same or different denier and/or the nontextured yarn and textured yarn have the same or different number of fibers;
- wherein the textile comprises a first edge and an opposite second edge, wherein at least a portion of the textile adjacent to the first and/or second edge comprises a plain weave, a twill weave, a satin weave, any derivation, or any combination thereof;
- wherein the textile has a first dimension in a relaxed position, wherein the textile is configured to reversible arrive at a second dimension under application of stress, and wherein the textile is biocompatible.
