FDA and Medtronic notified healthcare professionals of the Class 1 recall of Medtronic Neuromodulation Implantable Infusion Pumps, implantable devices for administering drugs to a specific site in the body to treat pain, spasticity and cancer. The company updated the labeling for the devices to include current patient management and treatment recommendations. The company received reports of inflammatory mass formations at or near the distal tip of intrathecal catheters which infuse opioids, baclofen, or chemotherapy drugs into patients. On January 16, 2008, Medtronic sent a letter to doctors who implant these devices and/or provide care to patients with the implanted device. The letter described the problem, patient risks, patient management, recommendations and next steps.
