Abstract
An apparatus for fixing a cardiac lead in place within the vasculature of the heart includes a coil having a normal helical shape and a stylet for holding the coil straight during insertion of the coil through a lumen of the lead. Upon retraction of the stylet, the coil returns to its helical shape along with the lead, forcing portions of the lead into contact with the vessel wall.
