Abstract
A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment.

18. A system for retrofitting a conventional prosthetic heart valve, comprising:
-
an off-the-shelf, non-expandable prosthetic heart valve having a sewing ring capable of being implanted using sutures through the sewing ring in an open-heart procedure;
an expandable anchoring member sized to contact and anchor to a heart valve annulus in an expanded state; and
coupling means for connecting the prosthetic heart valve to the anchoring member, the prosthetic heart valve thus being attached to the heart valve annulus via the anchoring member. - View Dependent Claims (19, 20, 21, 22, 23)
