Abstract

A lead having an extendable and retractable fixation mechanism (120) has a rotating terminal pin at the terminal end which rotates the fixation mechanism at the distal end. As the terminal pin (310) is rotated, the fixation mechanism is extended or retracted from the distal end of the lead. A threaded collar allows for the fixation mechanism to smoothly extend and retract from the lead, and allows for a 1:1 turn ratio between the terminal pin and the fixation mechanism. A fluoroscopic ring (150) disposed at the distal end of the lead provides information during the implantation process.
