A multi-conductor lead body having improved mechanical characteristics and improved manufacturability is disclosed. The lead body includes multiple conductors wound around a generally cylindrical or tubular, insulative core member. Ones of the conductors are spaced from other ones of the conductors by means of insulative strands or tubes wound around the core intermediate the conductors. The conductors may be stranded or cabled conductors. The core may be an insulative cylindrical or tubular member having a centrally located tensile reinforcement member, or may take the form of an insulated coiled conductor, allowing the use of a centrally located stylet to place the lead. Preferably, conductors and insulative strands or tubes separating the conductors are sized relative to the core member such that a gap is allowed between the conductors and associated insulative strands or tubes. In one embodiment, at least one of the conductors may be electrically and mechanically coupled to one or more electrodes such as a defibrillation electrodes. The electrodes may each be may be positioned along a respective portion of the outer surface of the conductor.

A medical electrical lead is provided that is readily manufactured using a minimal number of parts, has a reduced size and improved reliability during implantation and extraction. The lead includes a modular electrode head assembly that is joined to a lead body at a butt joint. The butt joint is stabilized in at least four possible ways: insulation tubing that spans the joint is bonded to the electrode head assembly; two cabled conductors extending the length of the lead body are coupled to the electrode head assembly; an electrode head alignment peg interlocks with and is bonded to the lead body; and a coil electrode is positioned across the butt joint on the outer diameter of the assembly and the lead body. The lead size is minimized by using a compact retraction stop mechanism, a low-friction, press-fit drive shaft seal, and a small diameter coiled conductor insulated by a thin-walled insulating tube.

A medical electrical lead includes an elastomeric multi-lumen tube, which includes a lumen having a substantially elliptical cross-section through which a conductor having a substantially circular cross-section may extend. The substantially elliptical cross-section of the lumen includes a minor axis having a first length and being deformable such that the first length of the minor axis extends to a second length.

A medical electrical lead with a tip-ring assembly optimized to resist damage during extraction. The lead includes an elongated plastic tube and at least two elongated conductors mounted in the plastic tube. A tip-ring assembly is mounted to the distal end of the tube, the tip-ring assembly including a ring electrode coupled to one of the conductors, a tip electrode located distal to the ring electrode and coupled to another of the conductors and two molded plastic components separately fabricated of a plastic harder than the plastic tube, adhered to one another and together defining a circumferential groove in which the ring electrode is located and mechanically coupled to the tip electrode. The tip electrode may be provided with a proximally extending electrode shank covered by a tine sleeve which is fabricated of a plastic softer than the molded plastic components and is adhered to more distally located molded plastic component. The more distally located molded plastic component preferably overlaps the electrode shank to provide a stronger structure.

A medical lead includes a lead body and an electrode formed by a plurality of coil turns and positioned about the lead body. A portion of a conductor extends from an internal lumen of the lead body, through an opening, to an external surface of the lead body, to electrically couple with the electrode; the portion of the conductor is press fit between at least one of the plurality of turns of the electrode and the lead body thereby making direct electrical contact with the electrode.

A medical electrical lead includes a first elongate plastic tube including an outer surface, a conductor extending within the first plastic tube, an electrode having an outer diameter, mounted exterior to the outer surface of the first tube and coupled to a distal portion of the conductor, and a second elongate plastic tube formed of a base polymer to which surface modifying end groups are attached. The second tube is mounted exterior to the outer surface of the first tube, extends from a point adjacent to the first electrode proximally, and has an outer diameter approximately equal to the outer diameter of the first electrode.
