Abstract: Prosthetic heart valve devices and associated methods for percutaneous or transcatheter heart valve replacement are disclosed herein. A heart valve prosthesis configured in accordance herewith includes a frame having a valve support and a plurality of support arms extending therefrom. The plurality of support arms may include a main support arm configured to extend from the valve support for capturing at least a portion of a valve leaflet of a native heart valve therebetween when the valve prosthesis is in an expanded configuration and deployed within the native heart valve. In addition, the plurality of support arms may include multiple supplemental support arms disposed about the circumference of the valve support that when deployed in the expanded configuration are configured to at least partially engage subannular tissue at the native heart valve.

Abstract: A delivery system for use with a prosthetic heart valve having a stent frame to which a valve structure is attached, includes a shaft assembly including a distal end and a coupling structure disposed near the distal end and configured to be coupled to a distal end of the prosthetic heart valve. The system includes a sheath assembly defining a lumen sized to slidably receive the shaft assembly. The delivery system is configured to transition from a loaded state in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve. The coupling structure is configured to provide a controlled expansion or contraction of the distal end of the prosthetic heart valve based on longitudinal movement of the distal end of the shaft assembly.

Abstract: A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the stent which includes a plurality of self-expanding struts and an annular sealing membrane. Each strut has a first end coupled to a distal end of the stent and a second end not coupled to the stent. Each anti-paravalvular leakage component is moveable between a compressed configuration and a deployed configuration. In the compressed configuration, each strut extends distally away from the distal end of the stent. In the deployed configuration, each strut extends proximally away from the distal end of the stent. In an embodiment hereof, the deployed strut has a C-shape and is twisted such that the C-shape lies in a plane substantially along or tangential with the outer surface of the stent. In another embodiment hereof, the deployed strut is rolled-up and extends radially away from the outer surface of the stent.
