Systems for quickly delivering a prosthetic heart valve

摘要

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 to 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. A catheter-based system and method for deployment is provided.

主权项

1. A system for delivering a prosthetic heart valve, comprising:
a valve component including a non-expandable, non-collapsible prosthetic valve surrounding a flow orifice, the valve component further including an expandable coupling stent extending from an inflow end or distal end of the prosthetic valve, the coupling stent having a contracted state for delivery to an implant position and an expanded state; a valve holder connected to the prosthetic valve of the valve component opposite the coupling stent; 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 lumen, past the holder and through the valve component.
