ABSTRACT:
This invention is directed to an implantable medication-dispensing device which is arranged for subcutaneous implantation. The device has hard body in which is located a liquid reservoir, an adjacent gas chamber, and a pump which is manually operable through the cutaneous layer for drawing liquid medication from the reservoir and dispensing it and directing it into the body tissue below the hypoderm. A refill membrane permits injection of medication into the reservoir so that the implanted device can be periodically refilled.
