Robotic System Treats Brain Clots With Steerable Needles

The odds of a person getting an intracerebral hemorrhage, or brain clot, are one in 50 over his or her lifetime. A new image-guided surgical system under development at Vanderbilt University employs tiny steerable needles - about the size of those used for biopsies - to penetrate the brain with minimal damage and suction away the blood clot that has formed. The system is a collaboration between mechanical engineer Robert Webster and neurosurgeon Kyle Weaver.
