    摘要： A tool for refilling an implantable pump having at least one reservoir. The tool includes a plurality of independent fluid channels; a fluid reservoir in fluid communication with a first one of the fluid channels; at least one pump fluidly coupled to the fluid channels, the at least one pump and the independent fluid channels differing from each other in number, wherein (i) a pump is configured to apply positive pressure to the first fluid channel so as to drive fluid from the fluid reservoir therethrough, and (ii) a pump is configured to apply negative pressure to the second fluid channel; and a connector for removably connecting the fluid channels to the at least one reservoir.

    摘要： Embodiments of an implantable electrolytic pump include an electrolysis chamber, a drug chamber and an osmosis chamber, the osmosis chamber having a first portion in contact with the drug chamber and a second portion exposed to facilitate contact with a surrounding fluid. The pump further includes a cannula for conducting liquid from the drug chamber and electrolysis electrodes within the electrolysis chamber for causing generation of a gas therein, the electrolysis and drug chambers being in contact such that gas electrolysis within electrolysis chamber forces fluid from the drug chamber into the cannula, contact between the drug chamber and the osmosis chamber permitting fluid admitted into the osmotic chamber from the surrounding fluid to offset volume loss from the drug chamber and prevent buildup of vacuum pressure thereon.
