MMI’s Symani Surgical System was used by Dr. Adnan Siddiqui at Buffalo General Medical Center/Gates Vascular Institute to perform indirect bypass, encephaloduroarteriosynagiosis (EDAS) operations in three adult patients with Moyamoya disease, the device developer said.

Moyamoya disease is a rare condition that restricts blood flow through the carotid artery in the skull.

The surgeries were the first in a neurosurgical clinical trial sponsored by the Jacobs Institute, a nonprofit medical device innovation center led by Siddiqui as CEO. That trial is an early feasibility study approved by the FDA.
