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: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.

Abstract: Systems, devices and methods for maintaining coronary access after implanting a prosthetic heart valve and/or a transcatheter prosthetic heart valve replacement procedure. Systems of the present disclosure include a support structure and a valve structure. The support structure includes inner and outer frame members that define at least one auxiliary passageway. Upon final implantation, the valve structure is connected to the inner frame member, and the auxiliary passageway provides for passage of an auxiliary access device. In some embodiments, the inner frame member is formed or provided by a stent otherwise maintaining the valve structure. In other embodiments, the valve structure is secured to a stent of a prosthetic heart valve that is implanted separately from the support structure.
