US 6,854,994 B2 · Medical electrical lead connector arrangement including anti-rotation means

Abstract

A lead connector arrangement includes a non-cylindrically shaped connector pin coupled to a lead conductor and a connector sleeve assembly for receiving the non-cylindrically shaped connector pin. The connector sleeve assembly includes an insert with an axial bore formed therein that complements the shape of the non-cylindrical connector pin. According to one embodiment, the non-cylindrical connector pin may be provided in the form of a triangular, square, rectangular, or hexagonal shape. The axial bore has a complimentary shape to receive the connector pin. When the connector pin is threaded through the connector sleeve assembly using a pull-wire device, the pull-wire device may be unscrewed from the connector pin without causing axial rotation of the lead conductor when the connector pin is fully inserted within the axial bore.

Dependent claims

A medical electrical lead connector arrangement, comprising:

a non-cylindrically shaped connector pin coupled to a lead conductor and including a tip having a threaded surface for coupling with a threaded pull wire;
and
a connector assembly adapted to receive the non-cylindrically shaped connector pin into a first end of a bore of the assembly, the connector assembly including a pull wire insertion site positioned in proximity to a second end of the assembly bore and an insert mounted within the assembly bore and having an axial bore formed therein that complements the shape of the connector pins;
wherein the connector assembly is adapted to couple the lead connector pin to an implantable medical device when the pin is received within the insert of the connector assembly.
