Test of an adjustable valve system for hydrocephalus shunts
Part of Brain & nervous system clinical trials.
This trial checks how safe and well a specific adjustable valve (Polaris 24) works in people with hydrocephalus who need a valve shunt. You may be eligible if you already have this valve implanted for a first shunt, a shunt replacement, or after an endoscopic procedure failed, and you do not have certain infection, bleeding, or heart-circulation conditions.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have already been implanted with the Polaris 24 adjustable valve system.
- The valve was put in for a first shunt, a shunt valve replacement, or because an endoscopic ventriculostomy (EVT) failed.
- You can legally and willingly give informed consent for the study.
- You do not have an infection anywhere along the shunt, or anywhere else in your body that doctors suspect could affect it.
- You are not taking blood thinners and do not have a bleeding tendency or blood in the fluid around your brain.
- You do not have a ventriculo-atrial shunt (a type of shunt going to the heart) tied to congenital heart disease or other heart/lung malformations.

This study tests a wireless sensor that measures the flow of cerebrospinal fluid through a shunt, which is a tube that drains fluid from the brain. The goal is to see how different shunt valve settings affect flow, which may help doctors manage symptoms better.
This study tests a new, noninvasive device placed on the skin over your shunt to see if it can detect when the shunt is open or closed. It may help doctors quickly check if the shunt is working without using X-rays or other procedures.
This study tests a small, wearable device that measures how fluid flows through your shunt during daily activities and sleep. It aims to help doctors better understand shunt function without needing repeated scans or hospital visits.
This study tests a new wireless device that measures fluid flow in a CSF shunt (a tube that drains fluid from the brain). You may join if you have a shunt under your skin across your collarbone and can use or be nearby the device for a month.
This trial is testing a wearable thermal device that checks if your CSF shunt is working properly. It may help understand if your headaches are linked to shunt problems. The study involves using the device at home for 30 days and going to a few follow-up visits.
This study is testing a new wireless device that checks if the fluid in your brain's shunt is flowing properly. It is for people who are about to have shunt surgery, to see if the device can help confirm whether the shunt is truly blocked.
