  • Publication number: 20200146691
    Abstract: Aspects of the disclosure include 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. Aspects of 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).

  • Patent number: 9445858
    Abstract: A bipolar electrosurgical device is disclosed. The bipolar electrosurgical device includes a handle having a shaft and a distal end. The handle can be coupled to a source of electrical energy and a fluid source. A U-shaped first electrode extends distally in a plane from a pair of openings on the distal end of the shaft. The first electrode is in electrical communication with one of an active pole or a return pole of the source of electrical energy. A longitudinal second electrode extends distally from a middle opening on the distal end of the shaft. The second electrode is coplanar to the first electrode and electrically isolated from the first electrode. The second electrode is in electrical communication with the other of the active pole or the return pole of the source of electrical energy. The second electrode forms a lumen configured to be in fluid communication with the fluid source and a fluid opening for dispersing fluid.
