Abstract

A docking station for a transcatheter heart valve is disclosed. The docking station is configured to hold and position the transcatheter heart valve in a circulatory system. The docking station may include an expandable frame. The docking station may include an enlarged first end portion having a first outer radial portion having a first main lateral dimension, an enlarged second end portion having a second outer radial portion having a second main lateral dimension, and a narrowed central waist portion having an inner radial portion having a second main lateral dimension, the inner radial portion has a third main lateral dimension less than the first and second main lateral dimensions. The retaining portion is at least partially defined by at least one of the first and second end portions, and the valve seat is at least partially defined by the waist portion. The docking station may be configured to adapt the native tricuspid valve to receive a smaller transcatheter heart valve.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 61 / 111,879, filed November 10, 2021, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to heart valves, and in particular to a docking station or docking stent comprising a transcatheter heart valve (THV) or for implanting a transcatheter heart valve. Background technique [0004] Prosthetic heart valves can be used to treat heart valve disease. The native heart valves (aortic, pulmonary, tricuspid, and mitral) serve to prevent backward flow or regurgitation, not forward flow. Congenital, inflammatory, or infectious diseases can render these heart valves less effective. These diseases can eventually lead to serious cardiovascular harm or death. The definitive treatment for this disease for many years has been surgical repair or valve replacement during open heart ...
