Tiny rotating device puts a new spin on blood-clot removal

The milli-spinner thrombectomy device uses spinning-induced forces to mechanically modify blood-clot microstructure, shrinking clot volume by up to 95% for rapid, safe removal. By densifying the clot’s fibrin network and releasing red blood cells, it offers a new strategy to improve success rates in treatments of blood-clot blockages, such as stroke. The ‘milli-spinner’ technology performed better than a conventional technique in a swine model.
