Electrically conductive/insulative over-shoe for tissue fusion
First Claim
1. An electrosurgical instrument comprising:
- a pair of juxtaposed jaw members pivotably associated with one another, at least one of which includes an electrically conductive surface disposed thereon in electrical communication with an electrosurgical energy source;
a selectively engageable over shoe adapted to engage the electrically conductive surface, the overshoe including;
a tissue contacting wall configured and dimensioned to selectively and substantially overlie the electrically conductive surface of the electrosurgical instrument, the tissue contacting wall including a plurality of apertures formed therethrough configured to allow current therethrough, the tissue contacting wall being fabricated from a non-conductive material.

Abstract
An over shoe for use with electrosurgical instruments having a pair of juxtaposed jaw members pivotably associated with one another, at least one of which includes an electrically conductive surface disposed thereon which is in electrical engagement with an electrosurgical energy source. According to one aspect of the present disclosure, the over shoe includes a tissue contacting wall configured and dimensioned to selectively and substantially overlie the electrically conductive surface of the electrosurgical instrument. The tissue contacting wall is fabricated from a non-conductive material and includes a plurality of apertures formed therethrough. In another embodiment, the tissue contacting wall is electrically conductive and is configured for selective engagement atop on of the jaw members.
