US 2010/0133003 A1 · IMPLANTABLE MEDICAL ELECTRICAL LEADS INCLUDING COIL ELECTRODES

Abstract

A medical electrical lead employing a conductive wire as an electrode and a method of its manufacture. The electrode includes a first length extending along a first, helical path, between a first end of the wire and a second length of the wire; the second length of the wire extends along a second path between the first length and a second end of the wire. A conductor of the lead may be mounted within the second length of the conductive wire, for coupling thereto, and a junction, preferably including a crimp and a weld, may be formed between the wire and the mounted conductor. Prior to coupling the conductor, the second length of the wire may extend at least 270 degrees and less than 360 degrees about an axis, which is offset from an axis of the first, helical path.

Dependent claims

A medical electrical lead comprising:

a longitudinally extending insulative body;
an elongate conductor extending within the body;
an electrode comprising a conductive wire, the wire extending from a first end thereof to a second end thereof and including a first length, a second length and a transition length extending between the first and second lengths;
the first length of the wire extending around the body and between the first end and the transition length, and the second length extending around the conductor, within the body, and between the transition length and the second end;
a junction formed between the second length of the wire and the conductor, within the body, the junction comprising:
a crimp between the second length of the wire and the conductor;
and
