Abstract

A programmable implantable insulin pump is disclosed. The pump includes an implantable pump and a hermetically sealed module. The module provides for varying flow rates of fluid being dispensed from the pump or may provide for a constant flow rate of such fluid. In the case of varying flow rate capabilities, the module preferably includes one or more sensors to determine information relating to the pressure of the fluid, electronics for analyzing the pressure information and determining the flow rate of the fluid, and a mechanism for physically altering the flow rate. First and second resistor capillaries are included in the implantable pump to provide a large range of flow rate capabilities between basal operation and bolus operation. Methods of dispensing a medicament to a patient utilizing such a system are also disclosed, as are variations of the pump system.
