Electrical stimulation leads and systems with folding anchoring units and methods of making and using
First Claim
1. An electrical stimulation lead, comprising:
- a non-conductive lead body having an outer surface, 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 extending through the lead body, each conductor of the plurality of conductors electrically coupling each of the plurality of terminals to at least one of the plurality of electrodes; and
at least one anchoring unit disposed around the outer surface of a portion of the lead body, each of the at least one anchoring unit having a first end and a second end and comprisinga lead attachment element having a longitudinal length and a central lumen within which a portion of the lead body is received, anda plurality of anchoring fins, wherein each anchoring fin is attached to the lead attachment element and each anchoring fin extends away from the lead attachment element when in a deployed position and is configured and arranged for contact with patient tissue to anchor the lead within the patient tissue, wherein each anchoring fin is configured and arranged to have a retracted position in which the anchoring fin folds down and lies next to the lead attachment element and does not overlap with any other of the plurality of anchoring fins in the retracted position, wherein each of the anchoring fins is attached to the lead attachment element along at least 90% of the longitudinal length of the lead attachment element.

Abstract
An electrical stimulation lead includes at least one anchoring unit and each anchoring unit includes a lead attachment element. Some anchoring units include one or more anchoring fins attached to the lead attachment element and extending away from the lead attachment element when in a deployed position for contact with patient tissue to anchor the lead within the patient tissue. Each anchoring fin also has a retracted position in which the anchoring fin folds down and lies next to the lead attachment element. Other anchoring units include one or more anchoring tabs defined by the lead attachment element. Each anchoring tab is partially separated from a remainder of the lead attachment element by at least one cutout and extends away from the remainder of the lead attachment element when in a deployed position for contact with patient tissue to anchor the lead within the patient tissue.
