Abstract
A chronic myocardial pacing lead for the delivery of stimulation energy to and the sensing of electrical signals from the myocardium of a human heart. In one embodiment the lead is bipolar, having a sleeve electrode implanted into the myocardium and a pad electrode positioned on the epicardium. The lead includes a drug for delivery through the sleeve electrode to the myocardium. The disclosed lead is highly flexible to minimize tissue reaction, this permits the lead to offer relatively low pacing thresholds, high impedance, and excellent sensing in a configuration which is relatively easy to implant.
