Beschreibung
Zusammenfassung:	A system includes a prosthesis and a delivery system for delivery thereof. The prosthesis includes a self-expanding frame and a plurality of attachment tabs extending from a first end of the frame. The delivery system includes a shaft, a piston disposed over the shaft, and a capsule which is movable relative to the piston. The piston includes an annular groove or a plurality of circumferentially-extending grooves on an outer surface thereof. In a delivery configuration of the delivery system, the plurality of attachment tabs are disposed within the annular groove of the piston, or the plurality of circumferentially-extending grooves of the piston, and the capsule covers and constrains the prosthesis in a radially collapsed configuration, with the capsule extending over the annular groove, or the plurality of circumferentially-extending grooves, of the piston and the attachment tabs received therein.
