Systems and method for anchoring a lead for neurostimulation of a target anatomy
First Claim
1. An electrical stimulation lead having a proximal end and a distal end, the lead comprising:
- at the distal end of the lead, a first branch having a first biasing member and a first insulation covering, the first biasing member disposed within the first insulation covering, the first insulation covering having a first inner surface;
at the distal end of the lead, a second branch having a second biasing member and a second insulation covering, the second biasing member disposed within the second insulation covering, the second insulation covering having a second inner surface,wherein the first and second branches define a receiving channel and 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 receive a target anatomy through the receiving channel and, 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 inner surface or the second inner surface, 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.

Abstract
A lead having proximal and distal ends. At the distal end, a first branch includes a first biasing member and a first insulation covering. The first biasing member is disposed within the first insulation covering, which in turn includes a first inner surface. At the distal end, a second branch includes a second biasing member and a second insulation covering. The second biasing member is disposed within the second insulation covering, which in turn includes a second inner surface. The branches define a receiving channel and a stimulation region. The biasing members are movable away from each other to receive a target anatomy through the receiving channel and biasly movable toward each other to retain the target anatomy within the stimulation region. An electrode is disposed on one or both of the inner surfaces adjacent to the stimulation region, and is operable to stimulate the target anatomy.

10. 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. - View Dependent Claims (11, 12)

13. 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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
