When treating stroke victims, doctors use a long, thin device called a guide wire to unclog the blocked blood vessels in the brain. But these manually controlled wires provide limited access to difficult-to-reach areas. Yoonho Kim, 33, developed a teleoperated robotic system that can wind its way through the brain’s vascular network. “My invention enables robotically assisted procedures for treating stroke and aneurysms with much improved safety and accuracy,” Kim says.
