Abstract
A permanently implanted insulin pump or combined insulin and glucagon pumps, controlled by a valve that expands and contracts due to osmosis as a result of changes in the blood sugar level. The valve is constructed from tissues harvested or grown from the patient'"'"'s body tissues to prevent rejection, infection or thrombosis. It operates the pump(s) though a blood vessel via a magnetic strip within the valve tissue and a reed switch located outside the blood vessel. The pump battery is recharged by electromagnetic induction in response to low battery warnings. Glucagon and/or insulin are refilled in response to low-level warning indicators, using self-sealing septa located near to the surface of the skin.
