An improvement to silicone insulation for implantable medical electrical leads includes a plurality of ultra high molecular weight polyethylene multi-filament fibers, wherein each of the plurality includes approximately 25 monofilaments and has a titer of approximately 25. The plurality of fibers are embedded within a wall of the insulation that has a thickness of no greater than approximately 0.008 inch. A first fiber of the plurality preferably extends helically, and a second fiber of the plurality preferably extends linearly such that the second crosses over or under and directly adjacent to the first at a plurality of points, which are spaced apart from one another along an overall length of the silicone insulation. The aforementioned wall thickness is maintained, since, at least at each crossing point of the first and second multi-filament fibers, a coincident cross-section of each of the fibers is compressed in the radial direction.

Implantable medical device conductor insulation and process for forming

An elongate body of a medical electrical lead includes at least one conductor formed into a coil that includes a first portion and a second portion, wherein the first portion extends within an outer insulation sheath and the second portion extends outside the outer insulation sheath to be exposed to an environment external to the lead body as an energy dissipating shunt.

An implantable component including a feedthrough assembly and a method for forming the feedthrough assembly wherein a coating forming a fluid barrier over an insulator, an insulator-to-terminal pin interface and an insulator-to-ferrule interface is incorporated.

Implantable device feedthrough assembly

Method of manufacturing an implantable device feedthrough assembly

An implantable lead having a silicone rubber lead body which has a reduced coefficient of friction on an internal or external surface. The reduction in coefficient of friction is accomplished by extruding a tubular lead body to define a plurality of small parallel longitudinally extending grooves on the inner or outer surface of the lead body. The grooves may be formed by means of a die having inwardly or outwardly directed projections that form the grooves during the extrusion process. The formation of the grooves during extrusion provides a lead body having a lower coefficient of friction without the necessity of additional manufacturing process steps and without additional manufacturing costs.
