Patent number: 7431721Abstract: Technique for bonding soft biological tissue having an incision therein with forceps adapted to grip a portion of tissue on both sides of incision. Electrodes are secured to forceps for contracting the tissue portion. An electrical power source provides a high frequency electrical signal to electrodes to be passed through the tissue portion. The electrical power source is controlled to provide electrodes with one voltage signal during a first of two stages, wherein the voltage rises linearly, and another voltage signal during a second of the two stages, wherein the voltage is stabilized and modulated with a low frequency rectangular signal. A clamping means applies force with the forceps to compress the tissue at one or different levels during two time periods while the high frequency voltage is passed through the electrodes. The tissue impedance is measured as a function of time, with its minimal value being determined and stored.Type: GrantFiled: May 27, 2005Date of Patent: October 7, 2008Assignee: Livo Tissue Connect, Inc.Inventors: Boris E.
