Sasha (microrobot system for the removal of blood clots)

History

2025: Product Announcement

On April 17, 2025, Artedrone, based in Paris, introduced the Sasha microrobot system, designed to treat stroke. The solution is capable of autonomously performing mechanical thrombectomy.

Stroke is an acute circulatory disorder in the brain, accompanied by tissue death and damage to the functions of the nervous system. Two main forms of the disease are distinguished - hemorrhagic and ischemic. In the first case, a hemorrhage occurs in the brain tissue. In ischemic form, a section of the brain suffers from a lack of nutrition arising from a violation of the blood supply, for example, blockage of the vessel with a thrombus. As a result, tissues begin to experience acute oxygen starvation, which provokes cell death. This leads to the loss of functions that the damaged area of ​ ​ the brain performed.

In ischemic stroke, the most effective and reliable method of removing blood clots from the arteries of the brain is thrombectomy. In particular, percutaneous mechanical thrombectomy is used, when a catheter with a stent is introduced through a large artery: a thrombus is captured and extracted through an incision in a vessel. However, as noted by Artredrone, only a small percentage of people suffering from stroke have access to competent medical facilities where thrombectomy procedures are performed. The Sasha system is designed to solve the problem.

The new technology is based on the use of magnetic autonomous microrobots. Thanks to Sasha, it is claimed that cardiologists and radiologists in cardiac centers will be able to carry out thrombectomy. The developers claim that the emergence of this system democratizes complex stroke interventions, which will radically change the treatment landscape. Thus, the burden of strokes worldwide can be reduced.^[1]
