    Abstract: 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.

    Abstract: A delivery system for prosthetic heart valves are provided. The delivery system includes a flexible shaft, a distal sheath capsule configured to contain the prosthetic heart valve, an inner steerable catheter including an inner distal flex component, and an outer steerable catheter including an outer distal flex component. The inner distal flex component includes a first cut pattern and a second cut pattern distal to the first cut pattern. The outer distal flex component includes a third cut pattern. The inner steerable catheter is rotatable at least 90 degrees relative to the outer steerable catheter when the third cut pattern of the outer distal flex component is disposed over at least a portion of the first cut pattern of the inner distal flex component and each of the inner steerable catheter and the outer steerable catheter is in the flexed configuration.
