Abstract
An apparatus for neuromuscular electrical stimulation is provided. The apparatus may be a stimulation lead having an elongated member made up of at least one conductor and an insulative sheath surrounding at least a portion of the conductor. A distal portion of the elongated member may include one or more electrodes and at least one fixation element to secure the one or more electrodes in or adjacent to a desired anatomical site for providing stimulation thereto. The stimulation lead has a strain relief portion on the proximal side of the one or more electrodes, configured to reduce axial forces on the distal region of the elongated member, and the effects thereof, to reduce the risk of, or even prevent, displacement of the one or more electrodes and to accommodate localized flexural motion. The apparatus also may include at least one fixation element sized and configured to be deployed between muscle layers to maintain the electrode position at the stimulation site.
