Electrical stimulation leads with multiple anchoring units and methods of making and using
First Claim
1. An electrical stimulation lead, comprising:
- a lead body having a distal end portion, a proximal end portion, and a longitudinal length;
a plurality of electrodes disposed along the distal end portion of the lead body;
a plurality of terminals disposed along the proximal end portion of the lead body;
a plurality of conductors electrically coupling the terminals to the electrodes; and
a plurality of anchoring units disposed along the distal end portion of the lead body, the plurality of anchoring units comprising a first anchoring unit and a second anchoring unit, wherein the first and second anchoring units each comprise a wide end portion and a narrow end portion, wherein a largest outer radius of the wide end portion is larger than a largest outer radius of the narrow end portion,wherein the first anchoring unit is disposed closer to the proximal end portion of the lead body than any other of the plurality of anchoring units, wherein the wide end portion of the first anchoring unit is disposed closer to the proximal end portion of the lead body than the narrow end portion of the first anchoring unit and the narrow end portion of the second anchoring unit is disposed closer to the proximal end portion of the lead body than the wide end portion of the second anchoring unit, and wherein at least one of the electrodes is disposed distal to all of the anchoring units.

Abstract
An electrical stimulation lead includes a lead body; electrodes disposed along a distal end portion of the lead body; terminals disposed along a proximal end portion of the lead body; conductors electrically coupling the terminals to the electrodes; and anchoring units disposed along the distal end portion of the lead body. First and second anchoring units each have a wide end portion and a narrow end portion. The first anchoring unit is disposed closer to the proximal end portion of the lead body than any of the other anchoring units. The wide end portion of the first anchoring unit is disposed closer to the proximal end portion of the lead body than the narrow end portion. The narrow end portion of the second anchoring unit is disposed closer to the proximal end portion of the lead body than the wide end portion.
