Abstract
An implantable pump for providing metered doses of a compound to an individual is described. The implantable pump includes a chamber for storing an individual dose of the compound, an inlet valve fluidly coupled to the chamber for controlling a flow of the compound into the chamber, and an outlet valve fluidly coupled to the chamber for controlling a flow of the compound out of the chamber and into the individual. The pump includes an inlet valve driver circuit operable for opening and closing the inlet valve, and an outlet valve driver circuit operable for opening and closing the outlet valve. A battery and a charging circuit that includes a capacitor are included in the implantable pump. The charging circuit is operatively coupled to the battery for charging of the capacitor. The charged capacitor is operable for supplying power to the valve driver circuits.
