Abstract
A hand-held instrument for electrically stimulating tissue of a living body in the presence of body fluid comprising an elongated, relatively fine, electrically conductive wire having a planar conductive surface generally transverse to the axis thereof at one end. Insulation carried flush to the tip of the wire is provided along the peripheral surface of the wire to prevent shunting of electrical stimulus by the body fluid through such surface. A tube encases the insulated wire in a manner such that a portion of the wire is external to the tube and is adjustable relative thereto.
