I work with InSightec. I can tell you that the ExAblate is able to focus ultrasound waves in various parts of the body, but has only been tested to ablate clots in preclinical studies. The same technology is currently approved to treat tumors within a woman’s uterus, and clinical trials are underway to investigate its safety and effectiveness in treating conditions such as the pain caused by bone metastases, multiple myeloma, prostate cancer, and breast cancer. The brain system is also being evaluated for treating functional brain disorders and brain tumors. http://www.thebrainhealth.com/stroke-on-left-side-of-brain.html
