Patent ID: 7890184

Claim:
A medical electrical lead, comprising: an elongate conductor including a first portion, a second portion and a layer of insulation; the second portion extending from the first portion, and the layer of insulation completely surrounding a circumference of the first portion and partially surrounding a circumference of the second portion; a conductive ring including a first terminal end, a second terminal end, opposite the first terminal end, an external conductive surface, an inner conductive surface having a first inner diameter and a second inner diameter; the first terminal end being disposed adjacent to the first portion of the conductor, the inner conductive surface extending around the second portion of the conductor and making electrical contact therewith, and the second inner diameter being disposed at the second terminal end and being greater than the first inner diameter; and a core component extending within the inner surface of the ring and including an outer surface; the outer surface of the core holding the second portion of the conductor against the inner conductive surface of the ring for the electrical contact, and the outer surface of the core being deformed by a compressive force of the second portion of the conductor forced against the core by the first inner diameter of inner conductive surface of the ring.
