Medtronic infusion devices are used for patients with severe intractable pain that does not respond to conventional techniques. The spinal column contains the receptors which transmit pain from the body to the brain. By placing a small catheter into the spinal fluid and connecting it to a small implantable pump, an extremely small steady infusion of pain medication can be delivered. This device binds and blocks the pain receptors inhibiting a pain signal from reaching the brain. For patients experiencing severe daily pain this outpatient technique allows patients to regain their independence and restore function. You may be a candidate for intrathecal drug delivery if you meet the following criteria: Multiple other treatment modalities have been tried and failed, you would not benefit from additional surgery, or you are dependent on opioid pain medication.
