Kenneth B Stokes, Keith J Proctor, Tommy D Bennett, Rick D McVenes: Universal tined myocardial pacing lead. Medtronic, Harold R Patton, April 5, 1994: US05300107 (117 worldwide citation)

A myocardial pacing lead includes two sets of at least two tines placed to oppose each other. The lead is pressed against the epicardium and is rotated until a rough porous tip abrades the epicardium and allows the tip and the first row of tines to penetrate the myocardium. Excessive penetration and ...
