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.

34. A method of controlled release of a percutaneous replacement heart valve in a patient where a bioprosthetic heart valve is indicated, comprising:
-
providing a replacement heart valve device and a delivery and implantation system; the replacement heart valve device including; a stent member that is collapsible, expandable and configured for percutaneous delivery; and a valve attached to the stent member, the valve including two to four individual leaflets; the delivery and implantation system including; a pusher member and a moveable sheath, wherein the pusher member includes a lumen for receiving a guide wire, wherein the moveable sheath includes a lumen configured for receiving the pusher member, and wherein the replacement heart valve device 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; after the providing step, advancing the delivery and implantation system over the guide wire within the patient to position the replacement heart valve device for deployment within the patient; after the advancing step, partially deploying the replacement heart valve device within the patient by pushing out the pusher member from the moveable sheath to expose a portion of the replacement heart valve device; and after the partially deploying step, recovering the portion of the replacement heart valve device within the moveable sheath that was exposed in order to address a problem with the position of the replacement heart valve device within the patient. - View Dependent Claims (35, 36, 37, 38)

39. A method of controlled release of a percutaneous replacement heart valve in a patient where a bioprosthetic heart valve is indicated, comprising:
-
providing a replacement heart valve device and a delivery and implantation system; the replacement heart valve device including; a stent member that is collapsible, expandable and configured for percutaneous delivery; and a valve attached to the stent member, the valve including two to four individual leaflets; the delivery and implantation system including; a pusher member and a moveable sheath, wherein the pusher member includes a lumen for receiving a guide wire, wherein the moveable sheath includes a lumen configured for receiving the pusher member, and wherein the replacement heart valve device 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; after the providing step, advancing the delivery and implantation system over the guide wire within the patient to position the replacement heart valve device for deployment within the patient; after the advancing step, partially deploying the replacement heart valve device within the patient by retracting the moveable sheath to expose a portion of the replacement heart valve device; and after the partially deploying step, recovering the portion of the replacement heart valve device within the moveable sheath that was exposed in order to address a problem with the position of the replacement heart valve device within the patient. - View Dependent Claims (40, 41, 42, 43)

44. A method of controlled release of a percutaneous replacement heart valve in a patient where a bioprosthetic heart valve is indicated, comprising:
-
providing a replacement heart valve device and a delivery and implantation system; the replacement heart valve device including; a stent member that is collapsible, expandable and configured for percutaneous delivery; and a valve attached to the stent member, the valve including two to four individual leaflets; the delivery and implantation system including; a flexible hollow tube catheter and a moveable sheath, wherein the flexible hollow tube catheter includes a lumen for receiving a guide wire, wherein the moveable sheath includes a lumen configured for receiving the flexible hollow tube catheter, and wherein the replacement heart valve device is collapsed onto the flexible hollow tube catheter to reside in a collapsed configuration on the flexible hollow tube catheter and is restrained in a collapsed configuration by the moveable sheath; after the providing step, advancing the delivery and implantation system over the guide wire within the patient to position the replacement heart valve device for deployment within the patient; after the advancing step, partially deploying the replacement heart valve device within the patient by pushing out the flexible hollow tube catheter from the moveable sheath to expose a portion of the replacement heart valve device; and after the partially deploying step, recovering the portion of the replacement heart valve device within the moveable sheath that was exposed in order to address a problem with the position of the replacement heart valve device within the patient. - View Dependent Claims (45, 46, 47, 48)
