ABSTRACT:
A lead assembly for fixation to a human heart via thoracoscopy is provided. The lead assembly includes a lead that has a connector for connection to a cardiac stimulator, such as a pacemaker, a cardioverter/defibrillator, or a sensing instrument. A fixation mechanism is coupled to the lead that includes a tubular housing and a proximally projecting hook that is adapted to engage heart tissue. The hook is pivotable between a retracted position and an extended position. The lead and the hook are manipulated by a stylet. The lead assembly also includes a tubular introducer that is passed through the chest wall of a patient and used to place the lead proximate the epicardium.
