Abstract

An electrosurgical system is provided which includes an electrosurgical energy source; a return pad including a conductive surface; and a return pad cable connector selectively connectable to the electrosurgical generator. The return pad cable connector includes a cord having a conductive wire disposed therethrough, the conductive wire have a first end which connects to the electrosurgical energy source; and a connector operatively coupled to the cord. The connector includes a conductive surface which is selectively engageable with a corresponding conductive surface disposed on the return pad and is in electrical contact with a second end of the conductive wire, the conductive surface of the connector including a conductive adhesive disposed thereon; and a non-conductive adhesive disposed about the periphery of the conductive surface of the connector for engagement with a corresponding non-conductive adhesive disposed about the periphery of the conductive surface of the return pad.
