RETAINING MECHANISMS FOR PROSTHETIC VALVES

Abstract: prosthetic heart valve assemblies and methods, apparatus, and systems used to deliver a prosthetic heart valve assembly. a prosthetic heart valve assembly includes an inner frame, a prosthetic leaflet section disposed within the inner frame extending between in inflow row of cells and an outflow row of cells of the inner frame, and an outer support stent. the inner frame is disposed within the outer support stent, and the outer support stent is coupled and/or fastened to the inner frame. the outer support stent includes a plurality leaflet capturing arms for capturing native leaflets between the leaflet capturing arms and a portion of the prosthetic heart valve assembly when the prosthetic heart valve assembly is implanted in a native valve. for example, the native leaflets can be frictionally secured between the leaflet capturing arms of the support stent and the inner frame.
