Abstract

A fixation arrangement on the outer surface of an electrode head at distal end of a pacing lead includes an attachment mechanism having at least one tine, the tine being connected to the electrode head by a tine base portion that includes an electrically controlled heat-responsive positioner. The electrically controlled heat responsive positioner allows the angular position of the tine relative to the electrode head to be selective adjusted by a temperature change in the positioner.
