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.

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, a first strip member folded over the inflow end of the frame and sutured to itself through the frame to form a first protective portion, and a second strip member folded over the outflow end of the frame and sutured to itself through the frame to form a second protective portion.

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.
