<p>The invention is directed to a dose control module (18) for manipulating the dosage of one or more pharmaceutical solutions emanating from an implantable drug infusion pump (14). The dose control module has a processor and other circuitry for manipulating flow valves (16) and other dose manipulators. Effluent catheters from one or more implantable drug infusion pumps (14, 28) may be connected to the dose control module. The dose control module may direct the effluent pharmaceutical solution to one or more catheters (20). These catheters direct the pharmaceutical solutions to treatment locations. The invention is also directed to induction coil valves for use in or with the dose control module. The use of induction coils permits the dose control module to determine valve position and counteract large directional magnetic fields produced by MRIs.</p> |
