Implantable drug delivery system
First Claim
1. A system for delivering a drug to a patient, comprising:
- a drug storage medium for storing a drug; and
one or more aggregations of semiconductor devices operatively connected to said drug storage medium for monitor and control of the dispensing of the drug;
wherein the system is implanted in the body of the patient at a drug delivery site for delivery of the drug to said site wherein said semiconductor devices are substantially spherical in shape.

Abstract
A miniature implantable drug delivery capsule system. The drug delivery system (400) comprises one or more ball semiconductor aggregations (404) and (406) facilitating release of a drug stored in a reservoir (402). The first aggregate (404) is used for sensing and memory, and a second aggregation (406) for control aspects, such as for pumping and dispensing of the drug. Notably, the aggregates (404) and (406) may be interconnected by a common bus (410) for communication purposes, or may be implemented to operate independently of each other. Each aggregate (404) and (406) is encased in a semipermeable membrane (408) to allow species which are to be monitored, and drugs to be delivered, to freely diffuse. The system (400) 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 (400), or delivery in accordance with measured markers.
