ABSTRACT:
A cardiac pacemaker electrode lead comprising an electrode tip, an electrical conductor electrically coupled to the electrode tip, an insulative sheath covering a portion of the electrical conductor, and a molding member for covering the uninsulated portion of the electrical conductor and including a distal end for forming a first lap joint with the electrode tip and a proximal end for forming a second lap joint with the insulative sheath. Foldable tines are formed on the molding member and when unfolded extend at an angle from the molding member to anchor the electrode tip in trabecular muscles inside the heart. When folded, the tines are received in a recessed portion of the molding member such that the tines are substantially flush with the exterior surface of the lap joints.
