Abstract: A medical infusion pump system is disclosed. The medical infusion pump system is a multi-reservoir infusion device for dispensing at least compositions of insulin and an amylin analog for treatment of subjects. Insulin and the amylin analog are stored in separate reservoirs, each reservoir being operatively connected to a motor for providing discharge pressure to the reservoirs. The motors may act independently such that insulin and the amylin analog may be injected at incongruent times. The medical infusion pump may automatically dispense the amylin analog into a subject's blood once the subject's blood-glucose levels rise above a specific threshold, or may dispense the amylin analog based on expected levels of blood glucose.
