Abstract
Abstract An intramuscular lead for the electrical stimulation of muscle tissue. The improved lead has a needle connected to a strand of suture, a coiled conductor coupled to the strand by a tapered section of the coiled conductor, an insulative cover covers part of the coiled conductor, and a terminal connector coupled to the coiled conductor provides a connection to a pulse generator. Through such a construction the lead may be more readily introduced through muscle tissue.
