Medical electrical lead connector ring

Abstract

A medical electrical device that includes an elongated body extending from a proximal end to a distal end having an inner surface forming an elongated body lumen, a conductor extending through the elongated body lumen, and an electrode positioned along the distal end of the elongated body and electrically coupled to a distal end of the conductor. A connector ring is coupled to a proximal end of the elongated body and electrically coupled to a proximal end of the conductor, and includes an inner surface forming a connector ring lumen extending along the connector ring. A first flange extends from the inner surface to a first flange distal end and forms a conductor channel extending along the inner lumen to position the conductor within the connector ring and to form the electrical coupling of the connector ring and the proximal end of the conductor.
