Everything you need to know about our medical care in one place
The ReFlow® Mini Flusher is a small device placed under the scalp as an accessory to the shunt system. Its purpose is to give the healthcare team a way to gently push fluid backward through the small openings at the tip of the ventricular catheter, which is the part of the shunt that sits inside the brain. By sending a flush toward these openings, known as the catheter inlet flow holes, the ReFlow Mini Flusher helps maintain, restore or increase flow through the ventricular catheter, helping keep the shunt flowing as intended.
Yes. The ReFlow® Mini Flusher was reviewed and cleared by the U.S. Food and Drug Administration (FDA) and has been used in patients since its commercial launch in 2023. Before being introduced into clinical practice, the device underwent extensive testing to evaluate its safety and performance. Because proper placement and use are important, Anuncia Medical has invested significant time and resources into training neurosurgeons, nurses, advanced practice providers and healthcare teams on the appropriate use of the ReFlow Mini Flusher. This training helps ensure the device is implanted and used as intended. As of May 2026, after thousands of training interactions with healthcare professionals and several years of clinical use, Anuncia Medical has received no reports of device malfunctions, no product complaints and no adverse events related to the ReFlow Mini Flusher. While no medical device can eliminate all risks associated with shunt surgery or hydrocephalus treatment, the ReFlow Mini Flusher has demonstrated a strong safety profile in clinical use to date. If there are questions about whether the ReFlow Mini Flusher is appropriate for a specific situation, your neurosurgical care team can provide guidance based on the patient's individual needs and medical history.
