Abstract:
1. An implantable lead assembly for a body implantable medical system adapted to transmit electrical signals between a proximal end portion of the lead assembly and a distal end portion of the lead assembly to thereby stimulate selected body tissue comprising: an elongated insulative sheath of flexible resilient material having at least one longitudinally extending lumen; an electrical conductor received within the lumen of the insulative sheath and extending between a proximal end and a distal end; at least one elongated super plastic alloy element slidably received within the lumen of the insulative sheath, the super plastic alloy element being bendable to configure the lead assembly to negotiate tortuous turns in the vasculature of the body; an electrical connector coupled to the proximal end of the conductor for releasable attachment to a stimulating pulse generator; and an electrode coupled to the distal end of the conductor; wherein the super plastic alloy element has a dislocation-free plastic deformation mechanism.
