ABSTRACT:
A patch electrode of the type which is surgically attached to the epicardium for use in an implantable arrhythmia treatment system is disclosed which has one or more regions of exposed electrode mesh on a side of the electrode in direct contact with the epicardium. The mesh is held in a flexible carrier having a periphery between the exposed mesh and the edge of the carrier. A layer of a drug or steroid is carried on the carrier in this peripheral region, the drug or steroid interacting with body fluid and thereby slowly releasing into the surrounding tissue. The drug or steroid may be selected to provide antiarrhythmia therapy, reduce inflammation, retard tissue growth or may be an antimicrobial drug. The layer carried on the carrier may be on surface thereof, contained in a shallow trough in the carrier, or impregnated within the carrier material. The layer may be carried on one or both sides of the carrier.
