Abstract:
1. An implantable pump for providing metered doses of a compound to an individual, said implantable pump comprising: a chamber for storing an individual dose of the compound; an inlet valve fluidly coupled to said chamber for controlling a flow of the compound into said chamber, wherein said inlet valve is an electrically actuated valve; an inlet valve driver circuit electrically coupled to said inlet valve and operable for opening and closing said inlet valve; an outlet valve fluidly coupled to said chamber for controlling a flow of the compound out of said chamber and into the individual, wherein said outlet valve is an electrically actuated valve; an outlet valve driver circuit electrically coupled to said outlet valve and operable for opening and closing said outlet valve; a battery; a charging circuit comprising a capacitor, said charging circuit operatively coupled to said battery for charging of said capacitor, said capacitor, when charged, operable for supplying power to said inlet valve driver circuit and said outlet valve driver circuit; and an interlock circuit, wherein said interlock circuit is operable to prevent said inlet valve driver circuit from electrically actuating the inlet valve to open the inlet valve and to prevent said outlet valve driver circuit from electrically actuating the outlet valve to open the outlet valve during the same time interval.
