Abstract

A prosthetic heart valve may include a stent, a valve assembly disposed within the stent, a flange, and a plurality of anchor arms coupled to the stent. The stent may have collapsed and expanded conditions and inflow and outflow ends. The flange may include a plurality of braided wires and may be coupled to the stent and may be positioned adjacent the inflow end of the stent in the expanded condition of the stent. Each anchor arm may have a first end coupled to the stent adjacent the outflow end of the stent, a second end coupled to the stent adjacent the outflow end of the stent, and center portions extending from the first and second ends toward the inflow end of the stent. The center portions may be joined together to form a tip pointing toward the inflow end of the stent in the expanded condition of the stent.
