Patent number: 11969205Abstract: A system for treating uterine tissue comprises an elongated shaft having a proximal end, a distal end, and a longitudinal axis extending between said proximal and distal ends. An energy applicator at the distal end of the elongated shaft is actuatable between a non-expanded shape to be inserted through a patient's cervical canal and an expanded shape to conform to the walls of the patient's uterus. A handle is coupled to a proximal end of the elongated shaft. The handle may include first and second moveable grips coupled to actuate the energy applicator with an upper spring and a lower spring disposed to urge the first and second moveable grips to move apart. An inflatable seal may be located at a distal end of the elongated shaft with a thermally insulating sleeve disposed over the elongated shaft proximal to the inflatable seal.Type: GrantFiled: May 15, 2019Date of Patent: April 30, 2024Assignee: Minerva Surgical, Inc.Inventors: Dominique Filloux, Dave Clapper, Eugene Skalnyi, Akos Toth, Sean Darby, Tejas N.

Publication number: 20240032992Abstract: The tissue cutting device comprises an elongated assembly including both an outer sleeve and an inner sleeve. The outer sleeve has a tissue-receiving window, and the inner sleeve has a distal end which cuts tissue as the inner sleeve is advanced past the window. The tissue is received into a lumen of the inner sleeve, and the inner sleeve lumen is typically enlarged in a proximal direction to reduce the tendency of resected tissue to lodge therein. The tissue displacement member is optionally provided at a distal end of the outer sleeve to further aid in dislodging tissue which becomes captured in a distal end of the inner sleeve of the lumen.Type: ApplicationFiled: October 13, 2023Publication date: February 1, 2024Applicant: MINERVA SURGICAL, INC.Inventors: Aaron Germain, Kyle Klein, Benedek Orczy-Timko, John H.
