System and method for providing even heat distribution and cooling return pads
First Claim
Patent Images
1. A return pad for use with an electrosurgical system, comprising:
- a conductive layer;
a contact layer configured to engage patient skin; and
an intermediate layer disposed between the conductive layer and the contact layer, the intermediate layer uniformly covering a substantial portion of the contact layer thereby forming a low impedance connection with the conductive layer and the contact layer and configured to pass electrical current therethrough, the intermediate layer further adapted to distribute current flow between the contact layer and the conductive layer.

17. A method for performing electrosurgery, comprising:
-
providing an electrosurgical return pad including a conductive layer, a contact layer configured to engage patient skin and an intermediate layer disposed between the conductive layer and the contact layer, the intermediate layer uniformly covering a substantial portion of the contact layer thereby forming a low impedance connection with the conductive layer and the contact layer and configured to pass electrical current therethrough, the intermediate layer further adapted to distribute current flow between the contact layer and the conductive layer, placing the electrosurgical return pad in contact with patient skin; generating electrosurgical energy via an electrosurgical generator; and supplying the electrosurgical energy to the patient via an active electrode. - View Dependent Claims (18, 19)
