FDA approves Medtronic's Vanta spinal cord neurostimulator for patients with chronic pain. The device does not require recharging and can last almost twice as long as comparable devices, up to 11 years. It uses AdaptiveStim™ technology to control the stimulation process, allowing for personalized settings for each patient. It also adapts stimulation settings as the patient's body position changes due to the built-in accelerometer. And SureScan™ technology allows patients with an implanted neurostimulator to have a full-body MRI.
