Systems and methods for coupling coiled conductors to conductive contacts of an electrical stimulation system
First Claim
1. A method for forming an implantable lead, the method comprising:
- a) placing a plurality′
of elongated conductors into a coiled configuration comprising at least one single-layer region and at least one multi-layer region;
b) disposing a first constraining element over the plurality of elongated conductors in proximity to an end portion of the plurality of elongated conductors;
c) uncoiling a first conductor of the plurality of elongated conductors to the first constraining element from a location closer to the end portion than the first constraining element;
d) disposing a second constraining element over a portion of the plurality of elongated conductors with the second constraining element axially spaced apart from the first constraining element and disposed closer to the end portion than the first constraining element, wherein the uncoiled end of the first conductor extends radially from the elongated conductors between the first constraining element and the second constraining element;
e) uncoiling a second conductor of the plurality of elongated conductors to the second constraining element from a location closer to the end portion than the second constraining element;
f) disposing a first conductive contact over the first constraining element;
g) electrically coupling an uncoiled portion of the first conductor to the first conductive contact; and
h) disposing a retaining element over a portion of the single-layer region to prevent the multi-layer region from unraveling.

Abstract
An implantable lead includes an elongated member. A plurality of electrodes are disposed on a distal end of the elongated member. A plurality of terminals are disposed on a proximal end of the elongated member. Each of a plurality of conductors electrically couples at least one of the electrodes to at least one of the terminals. The plurality of conductors are disposed in the elongated member in a coiled configuration and have an end portion. Each of a plurality of constraining elements is disposed over at least one of the plurality of conductors such that the underlying at least one of the plurality of conductors is maintained in the coiled configuration. At least one of the plurality of electrodes or terminals is disposed over the constraining element and electrically coupled to at least one of the plurality of conductors.
