Abstract
Abstract Method and apparatus for providing an improved electrical connection between an electrode placed on the surface of the body and the underlying tissue. The electrode, including an absorbent pad saturated with a conductive material, is adhesively affixed to the body surface. The elongated fibers of a brush are brought into contact with the absorbent pad and, with an appropriate amount of force applied to the brush, the fibers micro-puncture the body surface, forcing the conductive material into microchannels beneath the body surface fomed or enlarged by the fibers and into contact with the underlying tissue.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
A method of providing an electrical connection between a body electrode and the tissue beneath the surface of the human anatomy comprising the steps of: a. placing the body electrode in contact with the body surface, said body electrode comprising a flexible tape having an adhesive on the underside thereof, a layer of a porous, absorbant material affixed to the flexible tape, and a conductive electrode in overlying relationship with said layer, said layer being saturated with an electrolytic solution, and b. puncturing said layer and said body surface through the upper surface of said flexible tape by a sharp object such that a portion of said electrolytic solution is forced through the body surface into contact with the tissue therebeneath, whereby an electrical connection is made between the tissue and the conductive electrode.
Claim 2
Independent Claim
134 words
A method of providing an electrical connection between a body electrode and the tissue beneath the surface of the human anatomy comprising the steps of: a. placing the body electrode in contact with the body surface, said body electrode comprising a flexible tape having an adhesive on the underside thereof, a layer of a porous, absorbant material affixed to the flexible tape, and a conductive electrode in overlying relationship with said layer, said layer being saturated with an electrolytic solution, and b. puncturing said layer and said body surface through the upper surface of said flexible tape by a sharp object such that a portion of said electrolytic solution is forced through the body surface into contact with the tissue therebeneath, whereby an electrical connection is made between the tissue and the conductive electrode.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein said absorbant layer is saturated with said electrolytic solution prior to said layer being placed in contact with said body surface.
Claim 4
Dependent Claim
26 words
The method of claim 1 wherein said absorbant layer is saturated with said electrolytic solution after said layer is placed in contact with said body surface.
