Estimating the term…
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 percutaneously implantable replacement heart valve device comprising an expandable stent member and a flexible, compressible artificial valve made of biocompatible tissue material and disposed within the inner cavity of said stent member affixed at one or more points on said artificial valve's outer surface to said stent member, said artificial valve having cusps or leaflets formed by folding of a sheet of said biocompatible tissue material without affixing of separate cusps or leaflets or cutting slits into said material to form said cusps or leaflets.

A percutaneously implantable replacement heart valve device comprising an expandable stent member and a flexible, compressible artificial valve made of biocompatible tissue material and disposed within the inner cavity of said stent member affixed at one or more points on said artificial valve's outer surface to said stent member, said artificial valve comprising a leaflet or cusp portion formed by folding of a first sheet portion of said biocompatible tissue material without affixing of separate cusps or leaflets or cutting slits into said sheet to form said cusps or leaflets, and an outer tubular cuff structure formed by folding a second sheet portion of biocompatible tissue material, said first and second sheet portions being affixed together.
30-32. (canceled)
A percutaneously implantable replacement heart valve device comprising an expandable stent member and a flexible, compressible artificial valve made of biocompatible tissue material and disposed within the inner cavity of said stent member affixed at one or more points on said artificial valve's outer surface to said stent member, said artificial valve comprising a leaflet or cusp portion formed by folding of a first sheet portion of said biocompatible tissue material without affixing of separate cusps or leaflets or cutting slits into said sheet to form said cusps or leaflets.
