Rapid deployment methods for prosthetic heart valves
First Claim
1. A surgical method for delivering and implanting a prosthetic heart valve to an aortic annulus, the method comprising:
- creating an access path to an operating site at the aortic annulus of the patient;
attaching three guide sutures at three spaced locations around the aortic annulus and extending three pairs of free ends of the guide sutures out of the operating site;
preparing for implant a heart valve including a prosthetic valve having a non-expandable, non-collapsible orifice and surrounded on an inflow end by a sealing ring, the heart valve further including a plastically-expandable coupling stent connected to and extending from an inflow end of the prosthetic valve, the coupling stent having a contracted state for delivery to an implant position and an expanded state configured for outward connection to the aortic annulus, the coupling stent being connected to the prosthetic valve during the manufacturing process in a manner that forms the coupling stent and prosthetic valve into a unitary heart valve capable of being implanted together;
threading the three pairs of free ends of the guide sutures through spaced locations around the sealing ring;
advancing the heart valve along the guide sutures with the coupling stent in its contracted state to an implant position at the aortic annulus with the sealing ring positioned supra-annularly and the coupling stent in its contracted state extending into the aortic annulus; and
applying outward force on the inside of the coupling stent to convert the coupling stent from the contracted state to the expanded state into contact with the aortic annulus.

Abstract
A quick-connect heart valve prosthesis that can be quickly and easily implanted 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.
