Patent Images
1. A return pad, comprising:
- a backing having a top side, a bottom side, and a periphery;
at least one capacitive return electrode disposed on the bottom side of the backing layer, the at least one return electrode being adapted to connect to a generator; and
at least one ring sensor disposed on the at least one capacitive return electrode and in substantial concentric registration with the periphery of the at least one capacitive return electrode, the at least one ring sensor configured to connect to a measuring component that is operable to approximate contact quality of the at least one return electrode during electrosurgical application, the measuring component configured to communicate with the generator.

Abstract
A return pad includes a backing, at least one return electrode, and at least one ring sensor. The backing has a top side, a bottom side, and a periphery. The return electrode is disposed on the bottom side of the backing layer and is adapted to connect to a current generator. The ring sensor(s) is disposed in substantial concentric registration with the periphery of the backing and is configured to connect to a measuring component. The measuring component is operable to approximate contact quality of the return electrode during electrosurgical application and is configured to communicate with the generator.

13. A method for monitoring contact quality of a return pad of an electrosurgical system, the method including the steps of:
-
providing a return pad including; a backing having a top side, a bottom side, and a periphery; at least one capacitive return electrode disposed on the bottom side of the backing layer, the at least one return electrode being adapted to connect to a generator; and at least one ring sensor disposed on the at least one capacitive return electrode and in substantial concentric registration with the periphery of the at least one capacitive return electrode; activating the at least one ring sensor to communicate with a measuring component; and approximating the contact quality of the return electrode by analyzing at least one of the capacitance, impedance and resistance from the at least one ring sensor. - View Dependent Claims (14, 15, 16, 17)
