Boston Scientific nerve device no help in heart failure study

By Ben Hirschler BARCELONA (Reuters) - A Boston Scientific device that stimulates the vagus nerve â€" a superhighway connecting the brain to the rest of the body - failed to help patients with heart failure in a mid-stage clinical trial. Vagus nerve stimulation (VNS), which involves delivering mild electrical pulses to the nerve in the neck, is already used to treat epilepsy and depression - and researchers have been looking to expand its use to other conditions. Heart failure is a serious, progressive disease in which the heart fails to pump blood properly. Patients enrolled in the study had a VNS device implanted in their neck, near the right vagus nerve.
