Development of percutaneous intramuscular electrode for multichannel FES system

A percutaneous intramuscular electrode developed for controlling paralyzed extremities by functional electrical stimulation (FES) is discussed. The electrode was made of a Teflon-coated 19-strand rope wound from ultrafine SUS 316L stainless steel wires and was helically coiled for high flexibility. Because of low percentages of electrode failure in the body, stable and reliable FES was achieved for a long time.<
