Abstract
An ETV procedure includes forming a burr hole in a human skull; passing an endoscopic third ventriculostomy (ETV) probe through the burr hole; fenestrating the floor of the third ventricle with the ETV probe to form an opening in the floor; and measuring a flow of cerebrospinal fluid (CSF) with a flow sensor of the ETV probe. The ETV procedure further includes deploying a membrane eyelet into the opening; and measuring a flow of CSF through the opening with a flow sensor of the membrane eyelet.
