1. A hand held instrument for electrically stimulating exposed, subcutaneous tissue of a living body comprising:

  • an elongated, relatively flexible, electrically conductive wire element including a handle end and a tissue engaging end having a planar surface generally transverse to the axis of said wire element, said wire having sufficient rigidity to generally resist bending when in operable contact with said exposed subcutaneous tissue;

    a tube encasing said wire element and orienting said wire element along a predetermined path, wherein a predetermined portion of said wire element is external of said tube and is adjustable relative thereto;

    handle means disposed on the handle end of said wire element for manipulating said instrument;

    means for connecting said wire element to a source of electrical stimulation energy; and

    a sheath electrically insulating the peripheral surface along the length of said wire element wherein only said planar surface at the tissue engaging end thereof transmits electrical stimulus to said tissue when said wire element is positioned thereagainst.
