Abstract:
1. A two-part prosthetic heart valve for implantation within a native heart valve, comprising: a substantially cylindrical tissue-engagable bas portion expandable from a collapsed state to an expanded state, the collapsed state sized for delivery through a delivery catheter to a heart valve annulus and the expanded state sized to contact the heart valve annulus; and a leaflet subassembly including a self-expandable metallic support structure and three heart valve leaflets, the leaflets being attached to the support structure at commissures, wherein the support structure has a fabric covering and the three heart valve leaflets are attached to the support structure at least in part by stitches along the fabric covering; and mechanical coupling members on the tissue-engagable base portion and leaflet subassembly for allowing the leaflet subassembly to mechanically couple to the tissue-engagable base portion, wherein the mechanical coupling members on the tissue-engagable base portion comprising axial posts configured for connection to the mechanical coupling members on the leaflet subassembly; wherein the tissue-engagable base portion and leaflet subassembly are separate components and the leaflet subassembly is configured to mechanically connect to the tissue-engagable base portion at the time of an implant procedure for providing a prosthetic heart valve.
