Patent application number | Description | Published |
20120259323 | Impedance Matching Circuit - An impedance matching circuit may be used to adjust for manufacturing and design tolerances in a surgical instrument. The matching circuit may match the load of a thermal element with the impedance of a power source used to deliver electrical energy to the surgical instrument. The matching circuit may include capacitors, inductors, coaxial cables, varactors, transformers, resistors, and/or combinations thereof. The matching circuit may also comprise a circuit board or flex board layers which may be modified to adjust the impedance of the load. | 10-11-2012 |
20130023866 | SYSTEM AND METHOD FOR COOLING OF A HEATED SURGICAL INSTRUMENT AND/OR SURGICAL SITE AND TREATING TISSUE - A cooling system for a surgical handpiece may provide fluid flow to the surgical tip and to the internal electronic components to prevent temperatures that may damage or make the patient or surgeon uncomfortable. Tip directed gas further controls the tip-tissue interface by displacing blood or serum from the incision point, increasing precision and diminishing coagulum build-up. In the alternative, cooling fluid may be used to quench tissue being treated. | 01-24-2013 |
20130066310 | SEALING AND/OR CUTTING INSTRUMENT - A sealing and/or cutting instrument having a thermally active surface or element which may be used to seal and then cut tissue, ducts, vessels, etc., apart. The instrument may include a thermally active surface or element comprised of a conductor covered with a ferromagnetic material. The instrument may contact tissue with one or more surfaces comprised of a non-stick material. A sensor in communication with the instrument may be used to monitor a therapeutic procedure and signal when sealing and/or cutting of a tissue is complete. | 03-14-2013 |
20130158535 | SYSTEM AND METHOD OF CONTROLLING POWER DELIVERY TO A SURGICAL INSTRUMENT - A thermal surgical instrument having a system to control the delivery of power from an energy source to active element located on a tip. The system for controlling delivery to the tip may include a control algorithm which uses on or more measurements, such as tip current, SWR, and rapid changes in reflected power, to manage power without affecting cutting efficacy, and in a manner that may be imperceptible by a surgeon. The system may utilize a state machine to determine the current environment in which the tip may be in. Power delivered to the tip may be selectively managed according to a fixed power index or a repeatedly executed power profile. | 06-20-2013 |
