A 'revolutionary' device, which is implanted within a blood vessel in the brain, made of a flexible material called nitinol and of the size of a matchstick, may one day enable paralyzed people with spinal cord injuries to walk again, according to Melbourne researchers. According to reports, in 2017 a group of selected paralyzed people from Australia will receive the implant as a trial. EPA/DAVID CROSLING AUSTRALIA AND NEW ZEALAND OUT
