Implantable pacing lead technology

Lead technology is reviewed, beginning with the first known permanent implant and continuing through today's state-of-the-art implant. Nondislodging transvenous leads and epimyocardial leads (sutureless, screw-in leads) are described. Conductors, insulation, and electrodes are discussed. The emphasis today appears to be on improving carbon, screw-in, porous, platinized and steroid eluting electrodes, while future developments may include very thin bipolar leads, higher pacing impedance electrodes, and easier to implant and explant devices.<
