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: 20230389857Abstract: A system for accessing a patient's uterine cavity and detecting perforations in the uterus includes an elongated probe having a flow channel extending to a terminal outlet in a distal region of the probe. A fluid source is coupled to the flow channel, and a seal on the probe is positionable in an endocervical canal. The probe may be trans-cervically inserted into the uterine cavity, and a fluid may be introduced through the channel to flow outwardly from the terminal outlet into the uterine cavity. A parameter of said fluid flow is monitored to detect a perforation in the uterus.Type: ApplicationFiled: August 22, 2023Publication date: December 7, 2023Applicant: MINERVA SURGICAL, INC.Inventors: Dominique Filloux, David Clapper, Eugene Skalnyi, Akos Toth, Sean Darby, Tejas N.

Patent number: 8221452Abstract: Systems and methods introduce a closure material to seal a vessel puncture site. The system and methods provide a catheter adapted for passage through a tissue puncture and sized to occupy substantially all the tissue puncture. The catheter includes a lumen in fluid communication with a fluid delivery port adjacent the catheter distal end. One or more dispensers are in fluid communication with the catheter lumen for dispensing first and second fluid compositions in the catheter lumen. An actuator causes the first and second fluid compositions to be dispensed from the dispensers and mixed by flowing the first and second fluid compositions through a static mixer. The first and second fluid compositions are dispensed from the fluid delivery port as a fluid mixture that reacts in situ to form a nonfluent closure composition adjacent the vessel puncture site.Type: GrantFiled: February 13, 2008Date of Patent: July 17, 2012Assignee: Neomend, Inc.Inventors: Stuart D. Edwards, Ronald Lax, Theodore L. Parker, Thomas C. Wehman, Theodore Kucklick, Eugene Skalnyi

Patent number: 7294126Abstract: Disclosed is an ablation method and apparatus used to close veins for treatment of venous insufficiency disease. The apparatus includes a catheter proportioned for insertion into a vein, a pair of inflatable balloons spaced apart on the catheter body, and an ablation electrode array disposed between the balloons. According to the disclosed method, the catheter is introduced into the vein to be treated and the balloons are distended. Blood is flushed and aspirated from the site between the balloons. RF power is applied to the electrode array, causing scarring of the vessel walls and eventual sealing of the vein.Type: GrantFiled: January 5, 2004Date of Patent: November 13, 2007Assignee: CYTYC CorporationInventors: Russell M.

Publication number: 20060247614Abstract: A method and system for achieving hemostasis (the stoppage of bleeding) is described. RF (radio frequency) energy is used to ablate the surface of tissue to stop bleeding. The depth of destruction of the tissue can be controlled so as to desiccate and coagulate the tissue. In one implementation, an electrode carrier including bipolar electrodes is applied to the tissue, and RF energy transmitted through the bipolar electrodes to ablate the tissue. A layer of desiccated tissue can be created as well as coagulation of the tissue to achieve hemostasis.Type: ApplicationFiled: April 28, 2005Publication date: November 2, 2006Inventors: Russel Sampson, Eugene Skalnyi

Publication number: 20060135956Abstract: A medical device and procedure is described for occluding a fallopian tube. A tubal occlusion device is inserted into a uterine cavity. The device includes an RF applicator head including an electrode carrier with one or more bipolar electrodes thereon. During insertion, the RF applicator head can be in a closed position. The RF applicator head is positioned at a tubal ostium of a fallopian tube, such that a distal tip of the RF applicator head advances into the tubal ostium. The RF applicator head is deployed into an open position such that the RF applicator head approximates the shape of the uterine cavity in a region of the tubal ostium. Current is passed through the one or more bipolar electrodes to the tubal ostium to destroy tissue to a known depth, which precipitates a healing response in surrounding tissue that over time scars and occludes the fallopian tube.Type: ApplicationFiled: December 20, 2004Publication date: June 22, 2006Inventors: Russel Sampson, Eugene Skalnyi, Estela Hilario, J.
