Abstract: A tool arrangement for forming a tunnel in a vertebra to perform nerve ablation includes a tamp having a distal end portion that includes a tip for creating the tunnel in the vertebra and a curvable portion to direct the tip along a curved path within the vertebra; a first cannula including a cannula body that is straight along an entire length of the cannula body and configured to receive the curvable portion of the tamp and straighten the curvable portion; and a tool hub including a stationary cannula attachment coupled to the first cannula and a movable head coupled to the tamp and configured to move toward or away from the stationary cannula attachment to extend or retract, respectively, the curvable portion of the tamp from or into, respectively, the first cannula.

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.
