Abstract: An implantable prosthetic valve may comprise a valve body having a proximal end, a distal end, an outer surface, and an inner surface facing a flow channel, and a skirt including a first level forming at least a portion of the outer surface of the valve body and configured to be thromboresistant and a second level forming at least a portion of the outer surface of the valve body and configured to allow tissue ingrowth with the second level. A plurality of prosthetic valve leaflets may be positioned within the flow channel and extend inward from the inner surface of the valve body.

Abstract: A prosthetic heart valve including an annular frame and one or more detachable outer skirts and methods associated therewith. The frame has one or more outer skirts releasbly attached to an exterior surface of the frame. In some examples, an outer skirt is attached to the frame via at least one retaining suture formed by stitches looped around a pull suture and struts of the frame. Portions of the outer skirt are captured between the pull suture and the exterior surface of the frame along a suture line. Removal of the pull suture from the suture line enables the outer skirt and frame to separate as the stitches are pulled through openings in the outer skirt. In some examples, outer skirts can be releasably attached to the frame via bioresorbable couplers. Removability of the outer skirts can facilitate improvements in implant and explant procedures of the prosthetic valves.
