Abstract: A textured fabric for an implantable bioprosthesis is provided. The textured fabric can include a woven base layer and a plurality of loops projecting from the woven base layer. The plurality of loops are formed from a composite core-sheath yarn. The core can be made of a material that is different from the sheath. The core material can be selected to impart strength and resiliency to bending and the sheath material can be selected to impart a larger surface area or texture that facilitates cellular or tissue in-growth.

Abstract: A prosthetic heart valve includes a frame having a plurality of strut members, an inflow end, and an outflow end. 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 has a first layer and a second layer, wherein the second layer has a plush surface. The first layer is folded over a circumferential edge portion of the second layer to form a protective portion that extends beyond the strut members in a direction along a longitudinal axis of the prosthetic heart valve.

Abstract: Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. The prosthetic valve can comprise an annular frame, leaflets, an inner skirt, and an outer skirt. The outer skirt can be secured to the outside of the inflow end portion of the frame, the outer skirt having longitudinal slack that buckles outward radially when the valve is in the expanded configuration and which lies flat when the valve is in the collapsed configuration. In some embodiments, the outer skirt is stiffer in the axial direction of the valve than in the circumferential direction of the valve. In additional embodiments, the outer skirt comprises a self-expandable fabric comprising fibers made of a shape memory material having a shape memory set to enhance the radially outward buckling of the outer skirt. Methods of crimping such valves to a collapsed or partially collapsed configuration are also disclosed.

Abstract: A delivery cylinder for a prosthetic implant can include a first tubular portion and a second tubular portion. The second tubular portion has a plurality of strut members coupled to the first tubular portion that define a volume for containing the prosthetic implant in a radially compressed state. The strut members can include respective flex regions configured such that application of force to the strut members causes deformation of the flex regions and corresponding radially inward or outward movement of the strut members relative to a longitudinal axis of the delivery cylinder between an expanded configuration and a contracted configuration.
