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.

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.
