Abstract

A contactor for establishing electrical communication with organic tissue, the contactor including a cup-shaped housing of one-piece rubbery material including a closing end-wall connected across an annular sidewall with rim defining an open mouth into a main recess. An electrode in the recess comprises a contact plate with first side facing the mouth to contact organic tissue, and a second side with a pair of leg-like extensions and a center limiter post all of one-piece molded plastics coated with a thin layer of conductor preferably silver/silver chloride to be electrically conductive on the exterior surface of the electrode. The legs of the electrode snap fit against to physically and electrically connect with an electrically conductive venturi tube mounted extending through the housing, the venturi tube having a suction port positioned such that when high pressure gas is passed through the venturi tube, a vacuum is created within the housing recess.
