    Abstract: The disclosure includes methods, systems and devices for severing and optionally removing at least a portion of heart valve leaflets. Leaflets can be partially removed or entirely removed or otherwise, the leaflets can be severed or splayed in such a way as to avoid coronary blockage, LVOT obstruction, or access challenges in procedures where a prosthetic valve is to be implanted within a previously implanted prosthetic valve. The disclosure also relate to numerous devices for and methods of disabling one or more valve ligating devices to provide an unobstructed valve opening so that a prosthetic heart valve can be implanted within the opening. The ligation device(s) is disabled either by removing the ligation device(s) or severing one leaflet so that ligated leaflets can be separated. In some embodiments, the ligation device(s) are severed to disable the ligation device(s).

    Abstract: A delivery system for transcatheter implantation of a heart valve prosthesis. The delivery system includes an outer sheath component defining a lumen therethrough, an elongate tube having at least two flat wires longitudinally extending from a distal end thereof, and self-expanding first and second frames disposed in series within a distal portion of the outer sheath component and held in a compressed delivery configuration therein. The elongate tube and the at least two flat wires are slidably disposed within the lumen of the outer sheath component. In the compressed delivery configuration the at least two flat wires longitudinally extend along exterior portions of the first and second frames and are woven through adjacent ends of the first and second frames to releasably couple them to each other. Proximal retraction of the at least two flat wires from the first and second frames releases at least the first frame from the delivery system.

    IPC: A61F2/24

    Abstract: Delivery devices and device elements that provide steering capabilities and methods of steering such delivery devices during the delivery of a stented prosthesis to a target site. Various delivery devices include a shaft assembly having a plurality of lumens through which tension members that compressively retain the stented prosthesis to the shaft assembly are routed. By selectively tensioning one or more tension members, the shaft assembly can be pulled or steered in a desired direction. Various embodiments include one or more steering or stiffening rods that can reinforce the device or counteract any unintended bending or steering of the delivery device.
