摘要： A distal tip coupled to a body of an implantable medical device includes a canted passageway extending distally from a lumen of the body and an opening terminating the passageway and positioned in proximity to a distal end of the distal tip; a helical fixation element coupled to an elongated member extending within the lumen of the body is adapted to deflect along the canted passageway of the distal tip. The elongated member is adapted to move the helical member through the passageway of the distal tip and out from the opening and to rotate the helical element thereby affixing the helical element into an implant site.

摘要： A service kit for splicing body implantable leads having inner and outer coaxially-arranged coil wire conductors insulated from one another. A conductive pin having a distal portion with an outside diameter less than the inside diameter of the inner coil has a barbed tip that is screwed into the inner conductor coil. A shoulder portion of the conductive pin having a larger diameter bears against and retracts the inner coil with respect to the outer coil as the distal portion is screwed into the coil lumen. An insulating sleeve over the shoulder portion assures that the conductive pin does not contact the outer conductor coil. An adaptor housing physically holds the end of the coaxial lead being spliced, the conductive pin and the insulating sleeve. A first set screw through the adapter housing contacts the conductive pin allowing electrical contact thereto. A second set screw through the adapter housing has a sharpened pointed tip by which the outer insulation of the lead is pierced and contact is sustained with the outer conductor coil. The first and second set screws are electrically coupled to coiled wire conductors of the service kit. The entire assembly is fabricated from body compatible materials and suitably sealed against the ingress of body fluids to permit repair of chronically implanted leads.

摘要： A structure for use as an electrode on a pacing lead to be located some distance proximal to the distal end of the pacing lead. Two short lengths of wire having high electrical conductivity are cut to size. The coils of the outer conductor are welded together at the desired location of the ring electrode of the lead. The two short lengths of wire are welded to the outer conductor of the lead at the desired location of the ring electrode. An insulating sheath having an inside diameter close to the outside diameter of the outer conductor is slid over the outer conductor. The flexibility of the insulating sheath is sufficient to permit encasing of the two short lengths of wire, though the insulating sheath is caused to protrude at the two places directly over and corresponding to the two short lengths of wire. A conductive ring having an inside diameter sufficient to permit sliding over the insulating sheath and two points of protrusion is placed around the insulating sheath at the desired location of the ring electrode. The conductive ring is swaged to an outside diameter approximating that of the insulating sheath. The forces produced cause the two short lengths of wire to pierce the insulating sheath and come in contact with the conductive ring which thereby creates an electrically conductive path between the outer conductor and the conductive ring.

摘要： A medical electrical lead implant tool includes a gripping assembly, terminating a distal end of an elongate shaft, adapted to alternately grasp the lead and release the lead and to rotate the lead, and a user control terminating a proximal end of the shaft. An internal drive cable extends within the shaft coupling the gripping assembly to the user control. The user control facilitates single-handed manipulation of a slidable dial, which may be grasped by fingers of a hand for longitudinal and rotational manipulation when a stationary handle is held in a palm of the hand; the longitudinal manipulation causing the gripping assembly, via the drive cable, to alternately grasp the lead and release the lead and the rotational manipulation causing the gripping assembly, via the drive cable, to rotate the lead.

摘要： A connector system for use in coupling an implantable electrical lead to an implantable pulse generator, or other implantable electrical apparatus. The connector system includes a connector pin assembly, typically mounted to the implantable lead and a connector block, typically mounted to the electrical stimulator. The connector block is provided with a lumen, in which a plurality of resilient, elastomeric rings are lineraly arranged. the rings are so sized as to frictionally engage a connector pin which is provided with a plurality of conductive pads, each coupled to a conductor within the implantable lead. Certain ones of the elastomeric rings are conductive, and engage with the conductive pads on the connector pin. Others of the rings are nonconductive and act as insulators and fluid seals. The connector pin assembly is also provided with a circumferential groove, which interlocks with the deflectable beam members of a retainer mounted to the connector block. An alternative connector block embodiment employs a metallic spring element to contact conductive areas on the connector pin.
