摘要： A medical electrical lead having active fixation (40) which readily flexes within the cardiac tissue (18). In particular, the present invention is a medical electrical lead having fixation mechanism which is temporarily rigid. In a preferred embodiment of the invention, the medical electrical lead features a fixation helix (40) constructed from an absorbable material, such as mannitol. In an alternate embodiment of the present invention, a medical electrical lead is disclosed which features a fixation mechanism having a multi-layer construction. In that embodiment the fixation mechanism is fahioned of a first (42), rigid and absorbable, material and a second (41), readily pliable and nonabsorbable, material. Through such a construction the lead may be fixed in the tissue (18) such that over time the first material (42) is absorbed by the body and the second material (41) is left in position to flexibly fix the lead in place. In one embodiment the second material (41) is conductive and is used to achieve an electrical coupling to the body tissue.

摘要： An implantable endocardial lead (10) with a retractable helix (48). A specialized stylet (50) can be inserted into the lead (10) at the proximal end and passed through the lead to the distal end. Located at the distal end of the lead is a piston (44) supporting the helix (48). The piston is attached to a coiled trifilar conductor (22) and has an electrode (14) adjacent the helix. Immediately adjacent the piston proximally an additional first short coil of wire is interlocked between the wires of the trifilar conductor (22), providing a female thread within the conductor. The stylet has a second single strand short coil segment spot welded to the stylet adjacent a distal end therof. The stylet (50) is rotated to screw the second short coil segment on the stylet into the first short coil adjacent the piston.

摘要： A pulse generator for a cardiac pacemaker is adapted to be implanted beneath the skin and adjacent the musculus with either of its two sides facing the musculus and its other side facing outwardly of the patient's body, at the option of the implanting surgeon, according to the desired orientation of the receptacle of the header for connection of an electrode lead to the pulse generator, and at the same time avoiding the presence of spurious signals attributable to flexation of the adjacent musculus and twitching attributable to stimulation of the adjacent musculus during operation of the pulse generator when implanted. To that end, the entire surface of the case is coated with an electrically insulative, biocompatible film except along a portion of the edge of the case between its two major sides which is to serve as an anodal contact surface for stimulating and sensing cardiac activity of the patient.

摘要： A locally flexible dilator sheath (10) for separating encapsulating tissue from an implanted cardiac electrical lead. The dilator sheath includes an elongated tubular member (11) of a rigid stainless steel material, which is sized for placement of the tubular member over a cardiac lead that is implanted in the vascular system of a patient. The distal end (13) of the rigid tubular member is beveled to ease the separation of extremely tough tissue that encapsulates an implanted cardiac lead. To ease insertion around curves in the vascular system of the patient, the elongated tubular member includes a relieved portion (14). The relieved portion includes a relief pattern (15) of apertures (16, 17, 19, 23) in the elongated tubular member. The relief apertures preferably include diametrically opposed slots (24, 25) that extend perpendicularly into the tubular member. Adjacent pairs (44, 45) of slots are circumferentially offset at 90 DEG angle (26) to add further lateral flexiblity to the relieved portion. A polyester shrink tube (41) surrounds the relief apertures to provide integrity to the tubular member should the tubular member fracture when separating encapsulating tissue from the implanted lead.

摘要： A method of manufacturing an electrode (10) comprises molding a plurality of spaced conductive sections (20, 22, 24) which include a pin receptacle (42, 44, 46) for receiving a connector pin (P1, P2, P3) of a wire harness (16). A skeleton of conductive sections (20, 22, 24), connector pins (P1, P2, P3) and lead wires (L1, L2, L3) are placed in a mold which defines the electrode (10). A non-conductive polymer is molded to the skeleton to form an integral electrode (10) having an elongated body (12) of conductive sections (20, 22, 24) separated by non-conductive sections (26, 28). Multiple durometer polymers may be used to achieve desired levels of flexibility of the electrode (10).
