Robotic thread is designed to slip through the brain’s blood vessels

MIT engineers have developed robotic thread (in black) that can be steered magnetically and is small enough to work through narrow spaces such as the vasculature of the human brain. The researchers envision the technology may be used in the future to clear blockages in patients with stroke and aneurysms. Image courtesy of the researchers
Magnetically controlled device could deliver clot-reducing therapies in response to stroke or other brain blockages. Etherington explains that the new robotic threads could "potentially make it easier and more accessible to treat brain blood vessel issues like blockages and lesions that can cause aneurysms and strokes."

Gizmodo reporter Andrew Liszewski writes that a new thread-like robotic work developed by MIT researchers could be used to quickly clear blockages and clots that lead to strokes. "The robot would not only make the post-stroke procedure faster and faster, but it would also reduce the exposure to radiation that surgeons often have to endure," Liszewski explains.

MIT researchers have developed a new magnetically-controlled robotic worm that could one day help make brain surgeries less invasive, reports Chris Stokel-Walker for New Scientist. When tested on a silicon model of the human brain, "the robot could worm its way through hard-to-reach blood vessels."
