Researchers at the University of Twente and Radboud University Medical Center have developed untethered magnetic robots (UMRs) for wireless blood clot removal, marking a breakthrough in the treatment of vascular conditions like thrombosis . Among individuals with thrombosis, 1 in 4 fatalities each year are caused by the condition. Traditional treatments often struggle to reach clots in complex vascular networks, but wirelessly controlled microrobots offer a precise, minimally invasive solution. These UMRs are 3D-printed and designed in the shape of screws, each containing a 1mm x 1mm permanent magnet for controlled movement.
They are engineered to swim efficiently in the bloodstream and perform surgeries inside the body. Using real-time X-ray guidance, the robots can accurately locate and remove blood clots. In a study, researchers successfully demonstrated clot removal using UMRs in an…
