QUICK-CONNECT PROSTHETIC HEART VALVE AND METHODS
First Claim
1. A prosthetic heart valve, comprising:
- a non-expandable, non-collapsible prosthetic valve defining a flow axis comprising a sewing ring surrounding an inflow or distal end thereof, and an expandable coupling stent having an outflow or proximal end in contact with and continuously sutured to the sewing ring, the coupling stent extending from the sewing ring in a distal direction, the coupling stent having a contracted state for delivery to an implant position and an expanded state configured for outward contact with a surrounding heart valve annulus.

Abstract
A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve has a base stent that is deployed at a treatment site, and a valve component configured to quickly connect to the base stent. The base stent may take the form of a self- or balloon-expandable stent that expands outward against the native valve with or without leaflet excision. The valve component has a non-expandable prosthetic valve and a self- or balloon-expandable coupling stent for attachment to the base stent, thereby fixing the position of the valve component relative to the base stent. The prosthetic valve may be a commercially available valve with a sewing ring and the coupling stent attaches to the sewing ring. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment.

12. A prosthetic heart valve, comprising:
a non-expandable, non-collapsible prosthetic valve defining a flow axis with blood flow-occluding leaflets, the valve having an inflow or distal end, and a plastically-expandable coupling stent having an outflow or proximal end with a periphery attached along the distal end of the valve, the coupling stent extending from the valve in a distal direction, the coupling stent having a contracted state that is generally conical, tapering inward in the distal direction for delivery to an implant position and an expanded state that flares outward in the distal direction for outward contact with a surrounding heart valve annulus. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
