Abstract:
1. A prosthetic apparatus for implanting at the native mitral valve region of the heart, the native mitral valve having a native annulus and native valve leaflets, the prosthetic apparatus comprising: a main body comprising a lumen and configured for placement within the native annulus, the main body being radially compressible to a radially compressed state for delivery into the heart and self-expandable from the compressed state to a radially expanded state; at least one anchor coupled to and disposed outside of the main body, the anchor being coupled to the main body such that when the main body is compressed to the compressed state, a leaflet-receiving space between the anchor and an outer surface of the main body increases to receive a native valve leaflet therebetween, and when the main body expands to the expanded state in the absence of any radial inward forces on the main body or the anchor, the space decreases to capture the leaflet between the outer surface of the main body and the anchor; and an annular flange portion extending radially outward from an atrial end of the main body, the annular flange portion comprising an atrial sealing member that blocks blood from flowing beyond the atrial end of the main body outside of the main body when the prosthetic apparatus is implanted.
