Blood clots in the brain are a growing health problem with devastating effects. These clots have a 40 percent mortality rate, and survivors can suffer from brain damage. Treatment is extremely challenging, but researchers at Vanderbilt University hope a new robot will be able to help. The bot uses a steerable needle to clear out clots.
Doctors often avoid operating on brain blood clots due to their tricky location and the risk of causing collateral damage. The robot, however, needs only a small opening to do its work. It can be guided by ultrasound or CT imaging to the targeted spot in the brain where it sucks out the clot. The needle extends like a telescope and is curved to navigate bends.… Read more
