A spinal infusion pump is a device that delivers concentrated amounts of medication into the spinal fluid space through the use of a small catheter. The delivery of medication is continuous, and thus it eliminates pain from breaking through allowing patients whose quality of life is severely impacted to substantially decrease the pain that they feel. These pumps are generally offered to patients who have not responded to pain reduction treatment and who have chronic and severe pain. Patients have to meet certain screening criteria before a spinal infusion pump is implanted.
