Abstract: An bipolar electrosurgical instrument especially designed especially for use in freeing and rerouting of the internal mammary artery during coronary bypass surgery. It comprises a rigid pen-like handle having appropriate cut and coag control switches mounted thereon and a bendable tubular extension projecting from the distal end of the handle member. Mounted on the distal end of the extension is a blade holder designed to contain an ultrasonic transducer as well as the proximal end of the blade itself. The blade comprises a ceramic substrate having a pattern of metallization thereon defining a bipolar cutting gap along the side and end edges of the blade and a bipolar coagulating gap located inwardly from the side and end edges. A cable is used to join the implement to an electrosurgical generator and the individual wires in the cable extend through the pen-like body, the tubular extension and into the blade holder where electrical connections are made to the electrodes on the blade itself.
