A first electrode is positioned within an artery proximate an implanted intravascular stent. A second electrode is positioned at a separate location relative the position of the first electrode. Electrical energy is then delivered between the first and the second electrodes to produce an electrical field adjacent the implanted intravascular stent. When a intravascular stent is implanted in a coronary artery, the delivery of the electrical energy is coordinated to cardiac cycles detected in sensed cardiac signals, where the delivery of the electrical energy between the first electrode and the second electrode occurs during a predetermined portion of the cardiac cycle.

[ We claim:] [1.]1. A method, comprising:sensing cardiac signals, where the cardiac signals include a cardiac cycle;positioning a first electrode within an artery proximate an implanted intravascular stent;positioning a second electrode at a remote position outside the lumen of the stent; anddelivering at least one pulse of electrical energy between the first electrode and the second electrode during a predetermined portion of the cardiac cycle, at a repetition rate that is on the order of a frequency between heart depolarizations.
