Abstract

A replacement heart valve system and a method of implanting a replacement heart valve in a patient. The replacement heart valve system includes a radially self-expandable tubular body and a valve including a plurality of leaflets coupled to the tubular body. The tubular body includes interconnected struts defining circumferential rows of cells, and has an outflow end and an inflow end that flares radially outward so as to have a larger outer diameter than that of the outflow end. A first row of proximal-most cells formed at the inflow end includes circumferentially adjacent cells that are disconnected from each other so as to be spaced from each other in the circumferential direction. A method of implanting the replacement heart valve includes delivering from a delivery catheter the tubular body, and expanding the tubular body such that the proximal-most cells are disposed against the native heart valve annulus.
