Abstract
Implantable infusion apparatus has a main infusate reservoir and a smaller volume auxiliary infusate reservoir interconnected by a passage. Fail-safe electrical valve means controls infusate flow from the main reservoir to the auxiliary reservoir and from the auxiliary reservoir exteriorly of the apparatus so as to prevent infusate overdose in the event of valve failure.
