Abstract: A prosthetic heart valve includes a frame that is radially collapsible and expandable between a collapsed configuration and an expanded configuration, and defines a longitudinal axis. A leaflet structure situated within the frame, and a sealing member is disposed around the frame. The sealing member can include a first portion extending circumferentially around a portion of the frame, the first portion being configured to resiliently stretch in a direction along the longitudinal axis between a first state corresponding to the expanded configuration of the frame and a second state corresponding to the collapsed configuration of the frame. The sealing member can include a second portion extending circumferentially around a portion of the frame, the second portion being configured to resiliently stretch in a circumferential direction between a first state corresponding to the collapsed configuration of the frame and a second state corresponding to the expanded configuration of the frame.

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.

Abstract: A prosthetic heart valve includes a frame having an inflow end and an outflow end, and defining a longitudinal axis. The prosthetic heart valve further includes a leaflet structure situated at least partially within the frame, and a covering disposed around the frame. The covering includes a first woven portion extending circumferentially around the frame and including a plurality of texturized strands or yarns extending along the longitudinal axis of the frame. The covering further includes a second woven portion extending circumferentially around the frame and spaced apart from the first woven portion along the longitudinal axis of the frame. The texturized strands extend along the longitudinal axis of the frame from the first woven portion to the second woven portion and form a floating portion between the first woven portion and the second woven portion.

Abstract: 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.

Abstract: A prosthetic heart valve has a frame including a plurality of strut members, the frame being radially expandable and collapsible between a collapsed state and an expanded state, the frame having an inflow end and an outflow end and defining a longitudinal axis. A leaflet structure is situated at least partially within the frame. A covering is disposed around an exterior of the frame and includes a cushioning layer, a first strip of material coupled to the cushioning layer and folded to encapsulate apices of the strut members of the inflow end of the frame, and a second strip of material coupled to the cushioning layer and folded to encapsulate apices of the strut members of the outflow end of the frame. The cushioning layer includes texturized filaments that provide compressible volume and a plush surface to the cushioning layer when the frame is in the expanded state.
