Electrical stimulation leads and systems with elongate anchoring elements and methods of making and using
First Claim
1. An electrical stimulation lead, comprising:
- a lead body comprising a distal end portion, a proximal end portion, and a longitudinal length, wherein the lead body further comprises at least one anchoring lumen that extends longitudinally along at least a portion of the lead body, wherein the lead body further comprises at least one open slot that is spaced apart from each end of the lead body, wherein each of the at least one anchoring lumen is open at one of the at least one open slot and extends both distally and proximally from the one of the at least one open slot;
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;
at least one anchoring element at least partially disposed in one of the at least one anchoring lumen, wherein each of the at least one anchoring element comprises at least one bent portion that is biased to extend an extension portion of the anchoring element out of one of the at least one slot when the anchoring element is in a deployed position and can retract the extension portion into the respective anchoring lumen when the anchoring element is in a constrained position; and
an attachment member attached to each of the at least one anchoring element, wherein the attachment member is disposed proximal to each of the at least one slot, wherein the attachment member is a band disposed along the lead body.

Abstract
An electrical stimulation lead includes a body having distal and proximal end portions, a longitudinal length, at least one anchoring lumen, and at least one open slot spaced apart from each end of the lead body. Each anchoring lumen is open at a slot and extends both distally and proximally from the slot. The lead also includes electrodes; terminals; conductors electrically coupling the terminals to the electrodes; and at least one anchoring element at least partially disposed in an anchoring lumen. Each anchoring element includes at least one bent portion biased to extend an extension portion of the anchoring element out of a slot when the anchoring element is in a deployed position and can retract the extension portion into an anchoring lumen when the anchoring element is in a constrained position. The lead further includes an attachment member attached to each anchoring element and disposed proximal to each slot.
