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.

Publication number: 20230218816Abstract: A hysteroscopic fluid management system includes a saline source with an electrolyte concentration, at least one pressure mechanism for circulating saline to and from a targeted site and through a filter having filter characteristics back to the source, and a controller. The controller provides a saline inflow in a first flow path to the site and a saline outflow in a second flow path from the site through the filter and back to the source at a controlled flow rate. A diagnostic or therapeutic procedure is performed at the site in the presence of the saline. The filter characteristics and the controlled flow rate are selected to (1) cause substantially no change in the electrolyte concentration in the saline, (2) to prevent hemolysis of greater than 5% of filtered red blood cells exposed to the saline, and/or (3) to minimize effect on prothrombin time of plasma exposed to the filter.Type: ApplicationFiled: March 17, 2023Publication date: July 13, 2023Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: AARON GERMAIN, KYLE KLEIN

Publication number: 20220233233Abstract: Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool. Thus, over a first cutting portion, radio frequency current may help cut the tissue and over a second or over transition region, the RF current may initiate vaporization of the fluid or other liquid to propel the tissue from the cutting device.Type: ApplicationFiled: April 11, 2022Publication date: July 28, 2022Applicant: MINERVA SURGICAL, INC.Inventors: JOHN H.

A cutting member having a plurality of sharp edges is formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high RPMs to cut bone and other hard tissue. An electrode is carried in a distal portion of ceramic cutting member for RF ablation of tissue when the sleeve and cutting member are is a stationary position. In methods of use, (i) the ceramic member can be engaged against bone and then rotated at high speed to cut bone tissue, and (ii) the ceramic member can be held in a stationary (non-rotating) position to engage tissue and RF energy can be delivered to the electrode to create a plasma that ablates tissue.Type: ApplicationFiled: December 17, 2021Publication date: June 9, 2022Inventors: Aaron Germain, Kyle Klein, Michael D.
