Abstract
A sacral medical electrical lead which may be implanted and reliably fixed for a temporary period of time within the sacrum in a minimally invasive manner. The lead features a lead body having a electrical conductor positioned within an insulator sheath, a connector for electrically coupling the electrical conductor to a pulse generator, an electrode located on a distal end of the lead body, the electrode electrically coupled to the conductor, and an anchor for anchoring the lead body to sacral tissue, the anchor integral with the insulator sheath. In the preferred embodiment the anchor comprises a notched section in which the insulation of the lead body presents a macroscopically roughened surface which can thereby engage into the tissue without causing damage to the tissue.
