Abstract
Abstract A body implantable lead for the delivery of stimulation energy to a desired body site including a drug dispenser carried by the lead which retains a drug to be dispensed while allowing the dispensing of that drug at least adjacent the desired body stimulation site. The lead is provided with an electrode having a bore open to a drug storage chamber which contains an absorbent plug. The drug is loaded into the absorbent plug, prior to use, by soaking the electrode in a solution containing the drug.
