Abstract
A lead for connecting an electrical stimulation generator to an internal organ of the body via the vascular system includes a small diameter nonhollow multifilament lead body surrounded by a guide sleeve. The guide sleeve pushes against a sleeve stop at the distal end of the lead to impart axial motion to the lead with stylet-like action. After the lead electrode is properly positioned, the sleeve is removed by severing it longitudinally as it is pulled off of the lead. A plurality of radially deployable folding fins are arranged on the distal portion of the lead so that they can be wrapped around the lead body without overlap even though the combined length of the fins in one embodiment is greater than the circumference of the lead body. The electrically conductive core of the lead is preferably comprised of thousands of carbon filaments embedded in a resin matrix.
