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.

Abstract: Embodiments of prosthetic valves for implantation within a native mitral valve are provided. One embodiment of a prosthetic valve includes a radially compressible main body and a one-way valve member. In some cases, the prosthetic valves also include ventricular anchors and/or an atrial portion coupled to and disposed outside of the main body. Methods, devices, and systems for delivering such prosthetic valves to the native mitral valve and implanting them therein are also provided.

Abstract: This disclosure pertains generally to prosthetic devices and related methods for helping to seal native heart valves and prevent or reduce regurgitation therethrough, as well as devices and related methods for implanting such prosthetic devices. In some cases, a spacer having a single anchor can be implanted within a native heart valve. In some cases, a spacer having dual anchors can be implanted within a native heart valve. In some cases, devices can be used to extend the effective length of a native heart valve leaflet.

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.
