Method for fabricating a neurostimulation lead contact array
First Claim
1. A lead comprising:
- a lead body defining a first lumen extending through the lead body;
a first conductor disposed in the first lumen;
a first slit extending from an exterior of the lead body through at least a portion of the lead body to the first lumen; and
a first contact strip, wherein the first contact strip has a rectangular surface area, wherein a first portion of the first contact strip, including a first portion of the rectangular surface area, is disposed in the first slit and is in contact with a portion of the first conductor and wherein a second portion of the first contact strip, including a second portion of the rectangular surface area, is wrapped at least one full revolution around the lead body to form an electrode or terminal, wherein the first portion of the contact strip, the second portion of the contact strip, and the electrode or terminal have a same width.

Abstract
A lead includes a lead body defining a lumen extending through the lead body; a conductor disposed in the lumen; a slit extending from an exterior of the lead body through at least a portion of the lead body to the lumen; and a contact strip. A portion of the contact strip is optionally disposed in the slit and is in contact with a portion of the conductor. A second portion of the contact strip is optionally wrapped around the lead body. A method of making a lead includes disposing one or more conductors in a lumen of a lead body; forming a slit from an exterior of the lead body to the lumen to access a portion of at least one conductor disposed in the lumen; coupling a flat contact strip to the portion of the conductor, and wrapping the contact strip around the lead body.
