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.

Abstract: A docking device for a bioprosthesis is disclosed that can change shape and recover after a deforming stress is removed, that adjusts to surrounding conditions to accommodate different complex anatomic geometries, and that mitigates leakage around the bioprosthesis. The docking device can include a 3D woven fabric forming an internal surface, an outer surface, and a thickness therebetween. A filler can be coupled to the outer surface. A method for making a docking device is also provided. The method includes weaving a 3D woven fabric by interlacing a shape memory material, a low-melt thermoplastic polymer or resin having a melting point, and a high-tenacity biocompatible material; and pressing and heating the 3D woven fabric over a shape-setting mold at temperatures greater than the melting point of the low-melt thermoplastic polymer or resin.

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.

Abstract: A prosthetic heart valve has a frame including a plurality of strut members, an inflow end, and an outflow end. A leaflet structure is situated at least partially within the frame, and a covering is disposed around an exterior of the frame. The covering includes a cushioning layer, and a first strip member folded over an inflow circumferential edge portion of the cushioning layer to form a first protective portion. A second strip member is folded over an outflow circumferential edge portion of the cushioning layer to form a second protective portion. The first strip member and the second strip member are spaced apart from each other along a longitudinal axis of the prosthetic heart valve.
