Persistent Swallowing Difficulty Leads to Clinical Complications

Persistent swallowing difficulty, also known as dysphagia, is one of the most significant, early barriers to stroke recovery. It can lead to serious clinical complications and even increase the risk of mortality.

Introducing Phagenyx

The Phagenyx Neuromodulation System improves swallowing safety and efficiency by restoring the brain’s ability to initiate and coordinate safe swallowing, accelerating recovery from post-stroke dysphagia.

Promotes Neurologic Recovery

Phagenyx applies pharyngeal electrical stimulation (PES) to the sensory nerves and restores the brain’s control of swallowing function

Improves Swallowing Safety & Efficiency

Clinical studies show Phagenyx enables faster return to oral nutrition and reduces aspiration risk, supporting shorter hospital stays

Designed for Real-World Care

Phagenyx enables rapid, early intervention without disrupting clinical workflow—even for critically ill patients

Testimonials

Michael, Stroke Survivor

“They got my throat working again after 10 minutes on the first day. At the end of the 6th day—after 60 minutes of treatment—I’m swallowing and eating like normal. It gave me my world back.”

Andrei Alexandrov, MD

“Before Phagenyx, our SLPs had limited options in treating dysphagia post stroke. It’s the best-kept secret in the United States.”

Chrissy, SLP

“Phagenyx has allowed us to offer a new treatment to our patients that is evidence-based. We’ve seen patients progress faster than they may have with other available therapies.”
