Abstract: A delivery system for delivering an implantable heart valve includes an outer shaft and an inner shaft that is slidingly disposable within an outer shaft lumen, the inner shaft including a distal end region. A plurality of fingers extend distally relative to the distal end region of the inner shaft and are adapted to releasably engage an implantable heart valve. A plurality of looped sheathing aids extend distally from the distal region of an inner shaft lumen and are adapted to guide the implantable heart valve back into the outer shaft lumen when the implantable heart valve is pulled back into the outer shaft lumen. Each of the plurality of looped sheathing aids include a distal petal adapted to engage tissue adjacent a native valve annulus in order to limit distal advancement of the implantable heart valve during deployment of the implantable heart valve.

Abstract: A seal member for use with a replacement heart valve implant may include a tubular polymeric seal element configured to be disposed on an outer surface of a replacement heart valve implant, the tubular polymeric seal element defining a central longitudinal axis; and a reinforcement strip fixedly attached to the tubular polymeric seal element proximate a first end of the tubular polymeric seal element, the reinforcement strip extending circumferentially around the central longitudinal axis. The reinforcement strip may include a radiopaque element extending circumferentially around the central longitudinal axis.
