A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander.

A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable stent frame, thereby enabling attachment to the annulus without sutures. The prosthetic valve may be a commercially available valve with a sewing ring and the stent frame attached thereto. The stent frame may expand from a conical deployment shape to a conical expanded shape, and may have a cloth covering its entirety as well as a plush sealing flange around its periphery to prevent paravalvular leaking.

Rapidly deployable surgical heart valves

Coiled medical plastic tubing is set in the coil shape by exposing it to a radio-frequency field while it is subjected to slight radially inward pressure. The amount of pressure and the power of the RF field are so adjusted as to cause the rungs of the coil to lightly stick together without deforming or weakening the coil itself.
