ABSTRACT:
This vas cautery apparatus includes a bipolar needle electrode, a pencil hand control, and a cautery electronic circuit. The bipolar needle electrode comprises a unitary center conductor and tip and the center conductor may be effectively insulated from an outer conductor by an insulating tubing. A relatively easily manipulated electrical connector joins the bipolar needle electrode to the pencil hand control. An output waveform from the cautery electronic circuit has an alternating potential characteristic during periods of the waveform.
