Abstract
Techniques for implanting and refilling a device for delivering a treatment agent to a body. First and second chambers for holding treatment agent and delivery agent, respectively, are placed adjacent docking compartments adapted to receive a hypodermic needle through septums so that the expended delivery agent can be withdrawn and a new supply of treatment agent can be introduced without removing the device from its implanted position in a body.
