First-in-human Trial of Home Brain Pressure Measured Using Kitea ICP Sensor, Placed During Hydrocephalus Shunt Surgery.

Participants with hydrocephalus who are at risk of repeated bouts of hospitalisation associated with shunt failures and therefore likely to benefit from being able to monitor intracranial pressure will be recruited. 10 adult (\>16 years) and 10 children (1-15 years) participants will be recruited in a staggered fashion to allow appropriate evaluation of outcomes. Participants will be recruited when they present to hospital requiring a shunt placement (or revision). At the same time as this surgery, the Kitea Sensor will be placed in the brain near the shunt. Participants will be asked to make measurements of their brain pressure at home using the Kitea ICP System for the next 3 months. Aside from the placement of the Kitea Sensor and home measurements of ICP using the Kitea ICP system, all clinical interventions will be standard of care.
