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.

Claims

1. 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.

2. The lead connector arrangement of claim 1, wherein the non-cylindrically shaped connector pin comprises at least one planar surface.

3. The lead connector arrangement of claim 1, wherein the non-cylindrically shaped connector pin comprises a polygonal shaped connector pin.

4. The lead connector arrangement of claim 3, wherein the polygonal shaped connector pin comprises at least one of a biangular, square, rectangular, and hexagonal shaped connector pin.

5. The lead connector arrangement of claim 1, wherein the threaded surface of the connector pin tip is formed within a recess of the tip.

6. The lead connector arrangement of claim 1, wherein the connector assembly conforms to at least two types of medical device industry connector standards.
