Abstract
A cardiac pacing lead or other stimulation lead carrying a drug incorporated into a controlled release device. The lead is provided with an extendable fixation helix which is advanceable from the distal end of the lead in order to engage with the tissue to be stimulated and to maintain the distal end of the lead adjacent the tissue to be stimulated. The controlled release device is located within the fixation helix and is extended with the fixation helix when it is advanced out of the distal end of the lead. In its advanced position, the controlled release device is positioned adjacent the distal end of the lead, preferably in a position to contact the tissue to be stimulated.
