1. An electrode lead comprising:
- a lead body having a tubular side wall;
at least one electrode at a distal end of the lead body;
an actuatable member within a lumen of the lead body; and
at least one anchor wire having a proximal end attached to the actuatable member;
wherein;
movement of the actuatable member relative to the lead body moves the at least one anchor wire through at least one opening in the sidewall of the lead body; and
a distal end of the at least one anchor wire moves radially from the lead body relative to a longitudinal axis of the lead body responsive to movement of the actuatable member.

Abstract
One embodiment of an electrode lead comprises a lead body, at least one electrode at a distal end of the lead body, an actuatable member and at least one anchor wire. The actuatable member is positioned within a lumen of the lead body. The at least one anchor wire has a proximal end that is attached to the actuatable member. Movement of the actuatable member relative to the lead body moves the at least one anchor wire through at least one opening in the lead body.
