Abstract
A prosthetic apparatus for implantation at a native valve complex includes a main body configured for placement within the native valve, at least one downstream arm and at least one upstream arm, each coupled to and disposed outside of the main body. The main body includes a compressed state for delivery and an expanded state. In the expanded state, a space exists between the downstream arm and an outer surface of the main body to receive an edge of a native valve leaflet. A portion of the downstream arm is configured to extend behind the received native leaflet and engage a downstream surface of the native valve complex while the edge of the received native leaflet is not engaged by the downstream arm. The upstream arm is configured to engage an upstream surface of the native valve complex at a location opposite the portion of the downstream arm.
