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, wherein the lead body defines at least one anchoring lumen extending longitudinally along at least a portion of the lead body and at least one open slot extending longitudinally along the lead body, wherein each anchoring lumen has a distal end portion and a proximal end portion, wherein the distal end portion of the anchoring lumen is exposed by the at least one open slot associated with the anchoring lumen; at least one electrode disposed along the distal end portion of the at least one lead body; at least one terminal disposed along the proximal end portion of the at least one lead body; at least one conductor electrically coupling the at least one terminal to the at least one electrode; at least one thin, elongate anchoring element having a distal end portion and a proximal end portion, each of the distal end portion and the proximal end portion having a longitudinal length, wherein, for each anchoring element, the proximal end portion of the anchoring element is disposed in the proximal end portion of a one of the at least one anchoring lumen and the distal end portion of the anchoring element is configured and arranged preferentially to extend out of the open slot associated with the one of the at least one anchoring lumen and away from the lead body in a deployed configuration unless the distal end portion of the anchoring element is constrained in a constrained configuration with the distal end portion of the anchoring element lying in the distal end portion of the one of the at least one anchoring lumen and completely exposed by the open slot associated with the one of the at least one anchoring lumen.
