Abstract
A method of making a replacement heart valve device whereby a fragment of biocompatible tissue material is treated and soaked in one or more alcohol solutions and a solution of glutaraldehyde. The dried biocompatible tissue material is folded and rehydrated in such a way that forms a two- or three-leaflet/cusp valve without affixing of separate cusps or leaflets or cutting slits into the biocompatible tissue material to form the cusps or leaflets. After the biocompatible tissue material is folded, it is affixed at one or more points on the outer surface to the inner cavity or a stent.

A percutaneous bioprosthetic heart valve and a delivery and implantation system configured for percutaneous use where a bioprosthetic heart valve is indicated, comprising:
- a prosthetic heart valve including:
- a stent member having an inner channel, the stent member collapsible, expandable and configured for percutaneous delivery, wherein the stent member includes a tubular structure away from its central portion that flares at both ends in a trumpet-like configuration;
- and
- a valve means residing entirely within the inner channel of the stent member, the valve means including an outer cuff layer and two to four individual leaflets;
- a catheter including a pusher member and a moveable sheath, both the pusher member and the moveable sheath each including a lumen, wherein the pusher member is disposed within the lumen of the moveable sheath, and wherein the prosthetic heart valve is collapsed onto the pusher member to reside in a collapsed configuration on the pusher member and is restrained in a collapsed configuration by the moveable sheath.
