Stanford University researchers say they have developed a more effective method Handle strokes.
A new technique called Milli-Spinner thrombectomy has been shown to make the results more successful in patients experiencing stroke. Heart attackPulmonary embolism and other thrombotic-related diseases, according to a press release from the university.
Thrombus is aggregated by a thread-like protein called fibrin. A long, hollow rotating tube with a series of “fins and slits,” the mirispinner enters the body through the catheter and applies force and suction to the thrombus.

As a result, the size of the thrombus decreases to 5% of its original volume without breaking the fibrin thread.
That’s important. The researchers pointed out because breaking a blood clot can cause the fragment to escape and cause you to get stuck in hard-to-reach locations.

With Milli-Spinner, red blood cells are “released” and smaller fibrin clumps are removed from the body.
“and Existing technologiesThere is no way to reduce the size of the clot. In the release, Senior Author Renee Chao, assistant professor of mechanical engineering, said:

“What’s unique about Milli-Spinner is that it applies compression and shear forces to reduce the entire blood clot and dramatically reduces volume without causing rupture.”
Time is essential Treatment of ischemic strokethis is when the clot is blocking oxygen in the brain. Research shows that every minute during a stroke, 1.9 million brain neurons and 14 billion synapses are destroyed.
With current technology, first attempts will only remove the blood clots for about half the time, and will fail completely in about 15% of the time. (istock)
With current technology, clots are removed only about half the time in the first attempt, and the release is stated, completely failing at about 15% of the time.
“In most cases, we have more than doubled the effectiveness of our current technology, and due to the most demanding mass, only about 11% of our current devices are excluded. On our first trial, we open our arteries at 90% of the time.

“It’s a sea-changing technology that dramatically improves our ability to help people.”
Researchers’ findings incorporating both animal studies and machine-based flow models were published in Nature on June 4th.

The multispinner says it could be used for other applications, such as capturing and removing kidney stone fragments.
The team is currently working to approve new technologies for clinical use. Clinical trials It is expected to start soon.

“What really makes this technology exciting is the compact mechanism that is not just extracting them, but actively reshaping them and reconstructing compact clots,” Zhao said.
“We are working to bring this into the clinical setting, where we can significantly increase the success rate of thrombectomy. Save the life of patients. ”
