VARIABLE FLOW INFUSION PUMP SYSTEM

摘要

An implantable infusion pump system is disclosed. The pump system preferably includes an implantable pump (800) and a removable module (820, 820'). The module (820, 820') may provide 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 (820, 820') preferably includes one or more sensors (830, 831) to determine information relating to the flow rate, electronics (844, 846, 835, 844e, 844f, 849, 848, 850, 851, 853, 854, 855, 856) for analyzing the flow rate information, and a mechanism for physically altering the flow rate (821). Methods of dispensing a medicament to a patient are also disclosed, as are variations of the pump system.
