What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new, noninvasive device called the Rhaeos Shunt Monitoring System. It checks if cerebrospinal fluid (CSF) flows properly through a shunt, which treats hydrocephalus, a condition where fluid accumulates in the brain. The trial aims to determine if this small, wireless sensor can distinguish between functioning and non-functioning shunts without invasive tests or imaging. Participants should have a CSF shunt and no new or worsening symptoms of shunt issues. The device, placed on the skin, uses warmth to detect fluid flow but does not affect any medical treatment. While participants might not benefit directly, the study could improve future shunt testing. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could enhance future care for hydrocephalus patients.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It seems focused on monitoring the shunt function without altering your medical care, so you may not need to stop your medications.

What prior data suggests that this device is safe for monitoring CSF shunt flow?

Research has shown that the Rhaeos Shunt Monitoring System is safe and easy to use. It sits on the skin and monitors cerebrospinal fluid (CSF) flow through a shunt. The device does not break the skin or alter treatment. Similar devices have been used before and are generally well-tolerated.

The main risk involves mild skin irritation from the adhesive that secures the device. Temporary symptoms may occur if the shunt valve is adjusted for testing, but these effects are expected to be minimal. Overall, the device allows doctors to check shunt function without causing harm or discomfort.12345

Why are researchers excited about this trial?

Researchers are excited about the Rhaeos Shunt Monitoring System because it introduces a noninvasive way to assess cerebrospinal fluid (CSF) shunt flow in patients with hydrocephalus. Unlike traditional methods that may require imaging or surgical intervention to evaluate shunt function, this system uses a wireless thermal flow detection device placed on the skin, making it simpler and potentially more comfortable for patients. Additionally, the data collected is encoded and blinded, ensuring that it does not influence clinical decisions until more is understood about its efficacy. This trial could pave the way for safer, more efficient monitoring of shunt performance without the need for invasive procedures.

What evidence suggests that this device is effective for monitoring CSF shunt flow in hydrocephalus?

Research has shown that the Rhaeos Shunt Monitoring System holds promise for checking fluid flow in patients with hydrocephalus. In this trial, participants will undergo noninvasive assessment using this wireless device, which measures temperature changes to determine fluid movement through the shunt. This approach eliminates the need for invasive tests or imaging. Previous findings suggest that the system significantly advances shunt function monitoring, making it easier to detect shunt failures. These results indicate that the device could enhance how doctors verify shunt functionality, potentially reducing the need for more complex tests.12356

Are You a Good Fit for This Trial?

This trial is for children and adults who already have a working CSF shunt for hydrocephalus, have healthy skin over the shunt near the collarbone, and no new or worsening symptoms of shunt problems. People with hard-to-find shunts, certain valve settings, recent serious skin reactions to adhesives, or multiple catheters in the area cannot join.

Inclusion Criteria

Subject-reported or documented history of successful valve adjustment(s)
Signed informed consent by subject or a parent or legal guardian, health care agent, or surrogate decision maker (according to local statutes)
Existing ventricular CSF shunt with an available 'virtual off' setting which can be programmed noninvasively

Exclusion Criteria

Shunt is difficult to palpate, or the shunt depth at the device measurement location is deeper than 5 mm from the skin surface via ultrasound measurement
Shunt valve is set to an opening pressure of >= 300 mm H2O, or the shunt system is otherwise set to substantially prevent shunt flow (e.g. Certas Plus valve programmed to a setting of 8 or a ligated shunt)
Previous participation in a Rhaeos clinical study in which the study device (current generation) was used to acquire measurement data

What Are the Treatments Tested in This Trial?

Interventions

  • Rhaeos Shunt Monitoring System

Trial Overview

The study is testing a small wireless sensor placed on the skin over a CSF shunt to see if it can detect fluid flow without surgery or imaging. The device uses gentle warmth to measure temperature changes that show whether fluid is moving through the shunt.
