Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages Any age
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Study population: Individuals with at least one existing CSF shunt
Who may be able to join
- At least one existing ventricular CSF shunt, functional or non-functional (including an adjustable valve set to "virtual off," ligated shunt, uncorrected distal catheter disconnection or fracture, distal catheter fragment left in place during shunt surgery, or indication that the shunt is otherwise non-functional), with a region of overlying intact skin appropriate in size for application of the study device
- If more than one distal shunt catheter is present, at least one distal shunt catheter is at least 2 cm away from any other distal shunt catheter in the device measurement region
- Signed informed consent by subject or a parent, legal guardian, health care agent, or surrogate decision maker (according to local statutes)
- Signed medical records release by subject or a parent, legal guardian, health care agent, or surrogate decision maker (according to local statutes)

Who cannot join
- Presence of an interfering open wound or edema in the FlowSense device measurement area
- Patient-reported history of serious adverse skin reactions to silicone-based adhesives
- Use of the study device would interfere with standard patient care, or emergency surgery that cannot be delayed, or participation in the study will interfere with, or be detrimental to, administration of optimal healthcare to the subject
- Participation in any other investigational procedural, pharmaceutical, and/or device study that may influence the collection of valid data under this study

Questions about this trial
What is this clinical trial studying?
An observational study of Hydrocephalus, run by Rhaeos, Inc. at 8 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 15 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: Enrollment). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Correlation of measurement data (time frame: Approximately 1 hour). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2025.
