ABSTRACT:
A helix (10) is defined by two lengths of multistrand wire (14) each surrounded by flexible, biocompatible insulation (18). A silicon elastic sheath (30) surrounds the helix and extends to a terminal end of the electrode. At the terminal end, a portion of the wire is wrapped around a periphery of the sheath to define a tissue contacting surface (34). A shaft (42) of a polypropylene anchor (40) is inserted into a hollow core (20) of the helix and thermally deformed into mechanical engagement with the helix. The anchor has a plurality of polypropylene tines or barbs (44) which firmly engage the tissue within which it is inserted but which yield for electrode removal without ripping the tissue.
