COVERED PROSTHETIC HEART VALVE

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.
