Stanford researchers develop a stroke treatment that changes the game that doubles effectiveness

Stanford University researchers say they have developed a more effective way to treat blows.

It has been shown that the new technology, called Mili-Spinner thrombectomy, has more successful results for patients who have experienced strokes, as well as heart attacks, pulmonary embolisms and other disease-related diseases, according to a university press release.

Blood clots are grouped by protein similar to threads called fibrin. The Milli-Spinner, which is a long, hollow rotating tube and with a series of “fins and clefts”, enters the body through a catheter and applies strength and suction to the clot.

As a result, the blood clot reduces in size, up to only 5% of its original volume, without breaking any of the fibrin threads.

That is important because breaking the clot can cause them to escape and get stuck in places difficult to achieve, the researchers said.

With the mili-spinner, the red blood cells are “released” and the much smaller fibrin clot is eliminated from the body.

“With existing technology, there is no way to reduce the size of the clot. They trust to deform and rupture the clot to eliminate it,” said Senior Renee Zhao, assistant professor of mechanical engineering, in the launch.

“The only thing of the mili-spin is that it applies compression and cutting forces to reduce the entire clot, drastically reducing the volume without causing rupture.”

Time is the essence when treating an ischemic stroke, which is when the clot is cutting oxygen to the brain. Studies have shown that for every minute during a stroke, 1.9 million brain neurons and 14 billion synapses are destroyed.

With current technologies, the clots are only eliminated approximately half of the time in the first attempt, established liberation, and completely approximately 15% of the time.

“For most cases, we are more than double the effectiveness of current technology and for the most difficult clots, which we are only eliminating approximately 11% of the time with current devices, we are open the artery in the first attempt of 90% of the time,” said co -author Jeremy Heit, head of Neuroimagen and Neuro -intervention in Stanford, in the launch.

“This is a sea change technology that will drastically improve our ability to help people.”

The findings of the researchers, who incorporated studies in animals and machine -based flow models, were published on June 4 in Nature magazine.

The multiple spinner could be used for other applications, such as capturing and eliminating renal stone fragments, the launch said.

The team is now working to obtain the new technology approved for clinical use, and clinical trials are expected to begin soon.

“What makes this technology really exciting is its unique mechanism to actively remodel the clots and compact, instead of simply extracting them,” Zhao said.

“We are working to bring this to clinical environments, where the success rate of thrombectomy procedures and save the lives of patients could significantly increase.”
