Abstract
A replacement heart valve implant may include a tubular anchor member actuatable between a delivery and a deployed configuration, the tubular anchor member including an inflow end, an outflow end, and a plurality of anchor member intersection points, and defining a longitudinal axis extending from the inflow end to the outflow end, a plurality of valve leaflets, and a seal member secured to the tubular anchor member at the inflow end. An end surface of each of the plurality of valve leaflets may abut an inner-facing surface of the seal member. The plurality of valve leaflets each define a secured end and a free end. The secured end may be attached to the seal member adjacent the inflow end. The secured end may define the end surface, and the end surface may face toward the outflow end when the plurality of valve leaflets is in an everted position.
