Patent ID: 11406446

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 relates 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).
