Methods of making segmented electrode leads using flanged carrier
First Claim
1. A method of making a stimulation lead, the method comprising:
- providing a carrier comprising a body having a first surface, a distal end, and a proximal end, the carrier further comprising a plurality of flanges, wherein each flange comprises a leg portion attached to the body and extending away from the first surface at a non-zero angle with respect to the first surface;
attaching a plurality of segmented electrodes to the first surface of the body of the carrier;
attaching a plurality of conductors to the plurality of segmented electrodes;
forming the carrier into a cylinder, wherein the cylinder defines a central longitudinal axis through a center of the cylinder with the plurality of segmented electrodes disposed within the cylinder and the leg portions of the plurality of flanges extending toward the central longitudinal axis of the cylinder;
molding a lead body around the plurality of segmented electrodes disposed on the carrier and around the plurality of flanges; and
removing at least a portion of the carrier to separate the segmented electrodes.

Abstract
A method of making a stimulation lead includes providing a carrier with a body having a first surface, a distal end, and a proximal end. The carrier also includes flanges and each flange has a leg portion attached to the body and extending away from the first surface at a non-zero angle. The method further includes attaching segmented electrodes to the first surface of the carrier; attaching conductors to the segmented electrodes; forming the carrier into a cylinder with the cylinder defining a central longitudinal axis through a center of the cylinder with the segmented electrodes disposed within the cylinder and the leg portions of the flanges extending toward the central longitudinal axis of the cylinder; molding a lead body around the segmented electrodes disposed on the carrier and around the flanges; and removing at least a portion of the carrier to separate the segmented electrodes.
