Abstract
A miniature implantable drug delivery capsule system. The drug delivery system ( ) comprises one or more ball semiconductor aggregations ( ) and ( ) facilitating release of a drug stored in a reservoir ( ). The first aggregate ( ) is used for sensing and memory, and a second aggregation ( ) for control aspects, such as for pumping and dispensing of the drug. Notably, the aggregates ( ) and ( ) may be interconnected by a common bus ( ) for communication purposes, or may be implemented to operate independently of each other. Each aggregate ( ) and ( ) is encased in a semipermeable membrane ( ) to allow species which are to be monitored, and drugs to be delivered, to freely diffuse. The system ( ) may communicate with a remote control system, or operate independently on local power over a long period for delivery of the drug based upon a request of the patient, timed-release under control by the system ( ), or delivery in accordance with measured markers.
