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.

Extractable implantable medical lead

A medical electrical lead having an elongated lead body provided with an internal longitudinally extending lumen carrying an elongated stranded or cabled conductor and an electrode coil, located on said lead body. The coil is coupled to the conductor by a conductive sleeve having a tubular portion which has an internal lumen through which the conductor passes and a groove or bore which engages only a portion of a turn or turns of the electrode coil, such that the coil is oriented generally perpendicular to the internal lumen of said sleeve and to the conductor.

Medical electrical lead

A large surface electrode optimized for use as a subcutaneous defibrillation electrode. The electrode includes an insulative electrode pad carrying a large surface electrode. Both the upper and lower surfaces of the electrode pad are covered by a fabric mesh to reduce fluid build-up at the site of implantation. The defibrillation electrode is spaced at least 0.5' from the external periphery of the pad.
