Abstract
A helical winding formed by a wound ribbon and having a length considerably exceeding its diameter, is adapted for implantation into a patient's body. Adjacent turns of the winding partially overlap each other and overlapping portions of the ribbon engage each other to limit the relative axial motion of adjacent turns. At least a portion of the overlapping structure is oriented non-parallel to the longitudinal axis of the winding. In a method of manufacturing such a winding a ribbon is formed to a desired cross-sectional shape with a longitudinally expanding engagement structure. The ribbon is then wound on a mandrel to produce a winding of desired length, with adjacent turns partially overlapping each other and the engagement structure causing overlapping portions of the ribbon to be mechanically engaged so as to limit the relative axial motion of adjacent turns of the winding. Finally the mandrel is removed out of the wound winding. An implantable heart stimulator has a lead employing such a winding provided with an electrode pole at a distal end portion and a connector at the proximal end of the winding for connection to a pulse generator. A surgical tool employs such a winding with the distal end of the winding being provided with a cutting edge and the proximal end with a manipulator for displacing and rotating the winding.
