1. A method for positioning an electrode at or near target tissue in a patient, said method comprising:
navigating an elongate body having a distal portion and a proximal portion to position a first electrode, a second electrode, and at least two anchoring elements deployable through two or more apertures on a first side of the distal portion of the elongate body adjacent to the target tissue;
after the distal portion of the elongate body has been positioned adjacent the target tissue, actuating a displacement mechanism attached to a second side of the distal portion of the elongate body opposite to the first side to engage the distal portion but not the proximal portion of the elongate body against the target tissue to contact the first electrode, the second electrode, and the at least two anchoring elements against the target tissue, wherein the first electrode is positioned distally of a central portion of the displacement mechanism, the second electrode is positioned proximally of the central portion of the displacement mechanism, and a distal end of the displacement mechanism is positioned distally of the first electrode and the second electrode; and
after actuating the displacement mechanism to engage the distal portion of the elongate body against the target tissue, deploying the at least two anchoring elements from the two or more apertures located on the first side of the distal portion of the elongate body and proximal to a non-conductive distal tip of the elongate body.
