Using a laser inside a dementia patient's brain - Is anyone in the USA doing this?

[Bird_42]

In Russia, a Dr. has been experimenting with the transcatheter revascularization of the brains of dementia patients.

Using local anesthesia, he catheterizes a patient's femoral artery.  Then he sends a small laser device to the patient's cerebral arteries via the catheter. When the laser is inside the cerebral arteries, the laser delivers light energy to these arteries.

Here is a clinical trial:

It seems that this doctor is performing Peripheral Laser Atherectomy on cerebral arteries, and that he has had success in helping dementia patients.

A doctor has been working with this technique for about 10 years. Is there any doctor or scientist in the United States who is working with this technique? This sounds very interesting.
