Abstract: An implantable medical electrical lead includes an electrode assembly in which an electrical junction between a first conductor and an inner surface of a first electrode of the assembly is wedged within a first channel of at least one core member of the assembly, around which the first electrode extends. The at least one core member is formed from an insulating material, and the first channel may be one of a plurality of longitudinally extending channels arrayed around a circumference of a central lumen of the assembly, which is defined by the at least one core member. The first conductor extends along a length of the assembly, for example, defined between the first electrode and a second electrode thereof, in a helical path that travels around the central lumen.

Abstract: Pre-molded cylindrical sub-assemblies for inclusion in an implantable medical lead are described. The pre-molded cylindrical sub-assemblies comprise a cylindrical conductive element formed from a conductive material to define a substantially continuous interior surface and a substantially continuous exterior surface, and an insulative element formed from an insulative material molded onto the interior surface of the cylindrical conductive element. An interior surface of the insulative element defines a lumen of the pre-molded cylindrical sub-assembly configured to receive one or more elongated conductors of the implantable medical lead, and the cylindrical conductive element is configured to be electrically connected to one of the elongated conductors with the elongated conductors within the lumen. The cylindrical conductive element may act as an electrode, e.g., on a distal portion of the lead, or a connector, e.g., on a proximal portion of the lead.
