TRAILING TINE ELECTRODE LEAD

A medically implantable electrode lead for muscle stimulation comprising an electrode assembly with an exposed conductive distal tip which is coupled by an electrical conductor to a source of electrical pulses. The electrode assembly and electrical conductor are encased in an electrical insulator. The insulator has extending from it a plurality of flexible tines which are adapted to hold the exposed distal tip into position. To facilitate insertion of the distal tip into the desired location, especially when inserting the distal tip through a small opening such as a small vein, the insulator includes a transitional, truncated cone section between the distal tip and the tines. The outside diameter of the distal end of the cone section equals the outside diameter of the distal tip and the outside diameter of the proximal end of the cone section equals the outside diameter of the tines when they are folded into a closed position.
