Systems and method for anchoring a lead for neurostimulation of a target anatomy

An electrical stimulation lead having a proximal end and a distal end, the lead comprising:

• at the distal end of the lead, a first biasing member having a first branch and a second branch extending distally from the first branch;
• at the distal end of the lead, a second biasing member having a third branch and a fourth branch extending distally from the third branch,
• wherein the second and fourth branches are angled to define a receiving channel and a throat region with a throat width,
• wherein the first and third branches define a stimulation region proximal to the receiving channel,
• wherein the first and second biasing members are, upon application of a force to separate the first and second biasing members, movable away from each other to increase the throat width and receive a target anatomy through the throat region, and
• wherein the first and second biasing members are, upon removal of the force, are biased to automatically move back toward each other to retain the target anatomy within the stimulation region;
• and
• at least one electrode disposed on one or both of the first or second biasing members, the at least one electrode disposed adjacent to the stimulation region, wherein the at least one electrode is operable to electrically stimulate the target anatomy.

An electrical stimulation lead having a proximal end and a distal end, the lead comprising, the lead comprising:

• a housing located at the distal end of the lead;
• an anchor member having a first configuration disposed within the housing;
• a lumen coupled to the housing;
• and
• an anchor actuation device extending through the lumen and directly coupled to the anchor member, wherein the anchor actuation device is movable to distally urge the anchor member out of the housing into a deployed configuration in a vicinity of a target anatomy, and wherein the anchor member entangles with patient tissue to secure the lead in the vicinity of the target anatomy.
