MORGANTOWN, West Virginia – Nicholas Brandmeir, MD, neurosurgeon at WVU Rockefeller Neuroscience Institute, is the first neurosurgeon to successfully treat a hemorrhagic stroke patient using next-generation ARRIto flow® system.

ARRIto flow is the world’s first irrigating intracranial drain that offers a therapeutic approach to relieve intracranial bleeding. Dr. Brandmeir successfully completed the procedure on March 3.

“Over the past year, our team has used IRRAto flowactive fluid exchange technology to therapeutically treat our hemorrhagic stroke patients,” said Dr. Brandmeir. “We are thrilled to have the opportunity to be the first in the world to be able to use the next generation IRRAto flow system. The new IRRAflow control unit has welcomed improvements from a procedural workflow perspective, which will benefit our team and our patients. »

IRRAS, a global healthcare company focused on providing innovative medical solutions to improve the lives of critically ill patients, has launched its next-generation IRRAto flow system in the United States on February 22.

Hemorrhagic strokes occur when blood rushes into or around the brain and creates swelling and pressure that damages brain tissue cells. These strokes are usually caused by a traumatic injury or a weakened blood vessel that ruptures or leaks. Research shows that each year, hemorrhagic strokes account for only 15% of all strokes, but they are generally more deadly and are responsible for around 40% of all stroke deaths.

For decades, a typical treatment to clean the blood and reduce the pressure that builds up during a hemorrhagic stroke has been an external ventricular drain. This treatment is a passive, manual approach that relies solely on gravity to remove collected fluids. These drains are usually associated with blockages that can form and impact needed drainage capacity and other complications.

ARRIto flow, on the other hand, offers a therapeutic option known as active fluid exchange. Active fluid exchange combines needed drainage with automated, controlled irrigation that prevents drainage blockages from forming. The concept can also improve drainage by exchanging collected toxic matter with neutral fluids during the irrigation cycle. IRRAflow also continuously monitors the patient’s intracranial pressure and automatically controls treatment based on the patient’s situation.
