Publication number: 20200405379Abstract: A method comprising sealing a vessel residing within tissue between jaws of forceps by sensing an amount of tissue held within the forceps, the sensing by passing electrical current through the tissue by way of the forceps. The method comprises heating the tissue using electrical current, the heating such that impedance of the tissue changes at a first predetermined rate, the first predetermined rate selected based on the sensing. The method comprises desiccating the tissue using electrical current, such that the impedance of the tissue changes at a second predetermined rate different than the first predetermined rate. The method comprises ceasing application of the electrical current to the tissue when impedance of the tissue reaches a predetermined value. Sensing the amount of tissue held within the forceps comprises varying electrical current flowing through the tissue through the forceps such that impedance of the tissue changes at a third predetermined rate.Type: ApplicationFiled: September 16, 2020Publication date: December 31, 2020Inventors: Jonathan L. Gaspredes, Robert P. Lathrop, Thomas P. Ryan, David J. Miller, Jean Woloszko, Philip M. Tetzlaff

Patent number: 9649148Abstract: Electrosurgical systems and methods are described herein, the system including an electrosurgical probe with an active electrode disposed near the probe distal end, a system with a power supply for delivery of voltage to the active electrode and a controller that receives and processes a signal from a current sensor and a temperature sensor. The current sensor measures the current output of the power supply and the temperature sensor is adjacent an electrically conductive fluid located at a target site. The controller may be programmed to operate in a low voltage mode that limits the power supply to a low voltage output so as to determine whether the current output from the current sensor is within a current output range. This range is defined by predetermined upper and lower limits that are modified by at least one measured value.Type: GrantFiled: July 24, 2014Date of Patent: May 16, 2017Assignee: ArthroCare CorporationInventors: Jean Woloszko, Jonathan L.
