How IsoMed Works
The IsoMed pump delivers a constant flow of fluid as the drug in the pump reservior is forced through flow-restrictive tubing by pressurized gas.
Standard flow rates are 0.5,1.0 and 1.5/mL per day. All IsoMed pumps have a screened catheter access port to allow direct access to the cerebrospinal fluid.
