ABSTRACT:
A passive stabilizer for an electrode lead of a cardiac pacemaker for maintaining the electrode tip in interstitial contact with the endocardium until a sufficient amount of tissue ingrowth has occurred to secure the electrode tip in place. The passive stabilizer is secured to the lead of the cardiac stimulating device adjacent the electrode tip and comprises a sleeve having at least two groups of resilient tines, each group of tines being longitudinally displaced along the axis of the conductive lead with a first group being disposed between the second group and the electrode tip. The tines extend radially outwardly from the lead at a substantially right angle, with the tines of the first group extending outwardly a distance less than that of tines of the second group. Additionally, the tines of the first group are circumferentially staggered with respect to the tines of the second group.
