PERCUTANEOUSLY DELIVERABLE HEART VALVE AND METHODS ASSOCIATED THEREWITH
First Claim
1. A method, comprising:
- partially compressing and mounting a prosthetic heart valve upon a delivery catheter, the prosthetic heart valve comprising a tissue;
allowing the tissue to at least partially dry;
further compressing and mounting the prosthetic heart valve upon the delivery catheter; and
sterilizing and packaging the prosthetic heart valve and delivery catheter.

Abstract
A prosthetic heart valve implantable by catheter without surgery includes a substantially “dry” membrane or tissue material. In at least one embodiment, the tissue is folded in a dry state to form a tissue leaflet assembly that is then attached to a frame to form an implantable prosthetic heart valve. Alternatively, one or more tissue leaflets are operatively associated with a frame to form an implantable prosthetic heart valve. The implantable prosthetic heart valve is subsequently pre-mounted on an integrated catheter delivery system. The catheter delivery system that includes the implantable prosthetic heart valve is then packaged and transported while the tissue remains dry. The implantable prosthetic heart valve, while remaining substantially dry, can then be implanted into the receiving patient.

11. A method of preparing a percutaneous, trans-catheter prosthetic heart valve, comprising:
-
providing a membrane tissue from an organism; treating the membrane tissue with at least one chemical to produce a treated membrane tissue; drying the treated membrane tissue until it is a substantially dry tissue; attaching the substantially dry tissue to a frame; rehydrating the substantially dry tissue that is attached to the frame to form a rehydrated tissue; collapsing the frame with the rehydrated tissue attached thereto; and drying the rehydrated tissue attached to the collapsed frame until it is a substantially dry tissue. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
