A device for positioning an electrode in tissue includes: a lead body having a distal portion； an electrode array coupled to the lead distal portion； an anchoring element having an anchor tip and being operable in a first configuration in which the anchor tip is retracted within the lead and in a second configuration in which the anchor tip is extended outside the lead and configured to fixate within the tissue； and a displacement mechanism that is actuated to bias the electrode array or the anchoring element toward the tissue. A method for positioning an electrode in tissue includes: navigating, to the tissue, a lead with an electrode array, an anchoring element with a distal anchor tip, and a displacement mechanism； biasing the electrode array and anchoring element towards the tissue with the displacement mechanism； and deploying the anchoring element, and verifying fixation of the anchor tip within the tissue.
