Abstract

A technique for bonding soft biological tissue (2) having an incision (4) therein with forceps (8) adapted to grip a portion of the tissue on both sides of the incision. Electrodes (11) are secured to the forceps for contacting the tissue portion. An electrical power source (12) provides a high frequency electrical signal to the electrodes to be passed through the tissue portion. The electrical power source is controlled to provide the electrodes with one voltage signal during a first of two stages, and another voltage signal during a second of the two stages. During the first stage the voltage rises linearly. During the second stage the voltage is stabilized, and is modulated with a low frequency rectangular signal. A clamping means applies force with the forceps to compress the tissue at one level or at 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.
