Leads for electrostimulation of peripheral nerves and other targets
First Claim
1. An electrical stimulation lead comprising:
- at least one lead body having a distal end portion, a proximal end portion, and a longitudinal length;
a paddle body extending from the distal end portion of the at least one lead body;
a plurality of electrodes disposed along the paddle body;
a plurality of terminals disposed along the proximal end portion of the at least one lead body;
a plurality of conductors electrically coupling the plurality of terminals to the plurality of electrodes; and
an anchoring device threadably disposed in at least a portion of the paddle body, the anchoring device having a head element and a tissue-engagement element fixed to the head element,wherein rotation of the head element in a first direction urges the tissue-engagement element to extend out of the paddle body and rotation of the head element in a second direction, opposite the first direction, urges the tissue-engagement element to retract into the paddle body.

Abstract
An electrical stimulation lead includes at least one lead body having a distal end portion, a proximal end portion, and a longitudinal length. The lead further includes a paddle body extending from the distal end portion of the at least one lead body, electrodes disposed along the paddle body, terminals disposed along the proximal end portion of the at least one lead body, and conductors electrically coupling the terminals to the electrodes. The lead further includes an anchoring device threadably disposed in at least a portion of the paddle body. The anchoring device has a head element and a tissue-engagement element fixed to the head element such that actuation of the head element urges the tissue-engagement element away from or toward the paddle body.

15. An arrangement for electrical stimulation of a target tissue, the arrangement comprising:
-
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, and a plurality of conductors electrically coupling the plurality of terminals to the plurality of electrodes; and a stylet configured for insertion into the lead body, wherein the stylet is helically shaped; wherein, when the stylet is inserted into the lead body and the lead is implanted in the target tissue, at least the distal end portion of the lead body forms a helical shape that variably locates the plurality of electrodes around the target tissue in both a longitudinal and circumferential direction. - View Dependent Claims (16, 17, 18)

19. An electrical stimulation lead for stimulating a target tissue, the 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 plurality of terminals to the plurality of electrodes; a sheath configured for locating over at least a section of the distal end portion of the lead body, wherein the sheath includes a slit for sliding the sheath over the lead body and the target tissue, wherein at least the distal end portion of the lead body includes a helical shape that, when implanted in the target tissue, variably locates the plurality of electrodes around the target tissue in both a longitudinal and circumferential direction. - View Dependent Claims (20)
