Abstract
Lead placement apparatus to transmit electrical signals to stimulate selected body tissue includes an introducer handle supporting a tubular outer sheath of flexible resilient material including a rigid section and a deflectable section adjacent the distal end, enabling the deflectable section to deflect among a plurality of positions in orientations transverse of a longitudinal axis. An operative member on the introducer handle connected to the distal end of the outer sheath serves to move that distal end. An inner tubular sheath of flexible resilient material slidably received within the outer sheath includes a driving socket fixed to its distal end whereby, with a lead slidably received within the inner tubular sheath and including a driven socket fixed to its distal end for releasable mating engagement by the driving socket, an electrode at the distal tip of the lead can be advanced and directed to the selected body tissue for stimulation.
