COILED ANCHOR FOR SUPPORTING PROSTHETIC HEART VALVE, PROSTHETIC HEART VALVE, AND DEPLOYMENT DEVICE

摘要

A system including an anchor for docking a prosthetic valve at a native valve of a heart can have a first end, a second end, and a central axis extending between the first and second ends, and defines an inner space coaxial with the central axis. The valve prosthesis can include a protective layer or annular ring that surrounds a bottom edge of the second frame end. The protective layer or annular ring can include two layers, and the two layers can be different materials.
