1. An electrosurgical device comprising:
- a handle;
a first jaw member and a second jaw member connected to said handle by an actuator adapted to move said first jaw member with respect to said second jaw member;
a first surface on one of said first and second jaw members including an elongated spring electrode which extends from a proximal portion of said one jaw member to a distal portion of said one jaw member.

Abstract
An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedance, thickness, compressibility, density, vascularity, etc., especially in the performance of endoscopic procedures. The instrument provides two electrodes of different electrical potentials. One electrode is moveable with respect to the other electrode to vary the distances between the electrodes and thus the impedance of the tissue as presented to the generator. The electrode distances may be varied by an automated or user controlled device.
