Medical breakthrough: Blood clots destroyed in seconds without rupture risk

American engineers have unveiled a revolutionary mechanical device capable of destroying and removing blood clots within seconds — potentially transforming the treatment of strokes, heart attacks, and pulmonary embolism.

The new technique, named “milli-spinner thrombectomy,” uses a tiny rotating tool that compresses blood clots — rather than breaking them apart — eliminating up to 95% of the clot’s size in a matter of seconds.

According to researchers, traditional clot-removal methods — like suction, retrieval nets, and fragmentation — fail in as many as 30% of cases, especially when clots are dense and rich in fibrin.

These older approaches also carry the risk of clot rupture and recurrent vessel blockages. In contrast, the milli-spinner method uses rotational pressure and shear forces to compact the clot like cotton, pushing out red blood cells and leaving behind a condensed fibrin core that can be easily removed with suction.

In both laboratory and live animal trials — including on models simulating brain and lung arteries—the device successfully removed clots up to 17 mm in just 8 to 15 seconds, with no damage to blood vessels and zero recurrence of embolism.

Reported in Nature npj Viruses and cited by Russia Today, the findings suggest the device could revolutionize emergency vascular care, providing a safer, faster, and more effective alternative to current clot-removal surgeries.

Researchers emphasize that its key advantages include ease of use, versatility across different vessel types, and lower complication risks, making it a strong candidate for clinical use in treating life-threatening vascular conditions.
