Unitary Quick Connect Prosthetic Heart Valve and Deployment System and Methods
First Claim
1. A prosthetic heart valve for implant at a heart valve annulus, comprising:
- a non-expandable, non-collapsible annular support structure defining a flow orifice and having an inflow end;
valve leaflets attached to the support structure and mounted to alternately open and close across the flow orifice;
a suture-permeable ring circumscribing the inflow end of the support structure; and
a plastically-expandable coupling stent having a first end extending around the flow orifice and connected to the valve at the inflow end of the support structure, the coupling stent having a second end projecting in the inflow direction away from the support structure and being capable of assuming a contracted state for delivery to an implant position and an expanded state wider than the first end for outward contact with an annulus.

Abstract
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 coupling stent, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the coupling stent attached thereto. The coupling stent may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes a hollow two-piece handle through which a balloon catheter passes. A valve holder is stored with the heart valve and the handle easily attaches thereto to improve valve preparation steps.

8. A method of delivery and implant of a prosthetic heart valve system, comprising:
-
providing a heart valve including a prosthetic valve having a non-expandable, non-collapsible orifice, the heart valve further including an expandable coupling stent extending from an inflow end thereof, the coupling stent having a contracted state for delivery to an implant position and an expanded state configured for outward connection to the annulus; advancing the heart valve with the coupling stent in its contracted state to an implant position adjacent the annulus; and expanding the coupling stent to the expanded state in contact with and connected to the annulus. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A system for delivering a prosthetic heart valve, comprising:
-
a heart valve including a prosthetic valve having a non-expandable, non-collapsible orifice, the heart valve further including an expandable coupling stent extending from an inflow end thereof, the coupling stent having a contracted state for delivery to an implant position and an expanded state; a valve holder connected to a proximal end of the heart valve; a balloon catheter having a balloon; and a handle configured to attach to a proximal end of the valve holder and having a lumen for passage of the catheter, the balloon extending distally through the handle, past the holder and through the heart valve. - View Dependent Claims (17, 18, 19, 20, 21, 22)
