摘要： An implantable device or implant is configured to be positioned within a native heart valve to allow the native heart valve to form a more effective seal. The implantable device or implant can include a pair of paddles frame a coaptation element. The coaptation element defines a first area when viewed from above. The paddle frames define when viewed from above. A ratio of the second area to the first area is greater than or equal to 2 to 1.

摘要： An implant includes a frame, and a textile mounted on the frame. The textile includes fibers formed from a mixture of a polymer and an additive molecule. The additive molecule includes a polyurethane backbone and one or more fluorinated end-groups at at least one end of the backbone. Other embodiments are also described.

摘要： A fabric having a honeycomb weave pattern is provided for use with medical implants. The fabric may be heat treated to increase a thickness and texture of the fabric. The fabric may be compliant and compressible for providing cushioning within a patient's body. For example, the fabric may be applied to a prosthetic valve to cushion a portion of the prosthetic heart valve. The fabric may also be textured to provide enhanced friction between the prosthetic heart valve and the surrounding native tissue. Enhanced friction may be achieved by weave patterns or by the inclusion of protrusions or barbs in the fabric.

摘要： An implantable prosthetic valve may include an annular frame having an inner surface and an outer surface and the frame has an inflow end and an outflow end and a central longitudinal axis extending from the inflow end to the outflow end. A leaflet structure may be positioned within the frame. An inner skirt may be positioned along the inner surface of the frame. An outer skirt may be positioned around the outer surface of the frame. Various portions of the leaflet structure, the inner skirt, or outer skirt may incorporate a material inclusive of electrospun silk.
