Publication number: 20220355019Abstract: A fluid management system includes a pump connectable to a fluid source. An inflow line removably connects to a cannula for delivering a fluid flow from the pump into a surgical site, such as a joint cavity. A flow pressure sensor is coupled to measure flow pressure in the inflow line and produce a measured pressure value, A controller is connected to the pump and the flow pressure sensor, and the controller maintains a pressure set point by controlling a pump speed based on a backpressure-adjusted pressure value calculated by subtracting a backpressure value selected from a backpressure table from the measured pressure value. The BAPV is monitored to determine whether the BAPV deviates outside an initial BAPV range, and corrective measure are taken should such deviations occur.Type: ApplicationFiled: July 22, 2022Publication date: November 10, 2022Inventors: Steffan Benamou, Michael D.

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.
