This is a prospective, single-center, open label, single-arm pilot study of the eShunt System. The study population consists of patients with post-aneurysmal subarachnoid hemorrhage (SAH) treated for increased intracranial pressure (ICP) resulting in symptomatic hydrocephalus using an external ventricular drain (EVD) to facilitate CSF drainage and who cannot be weaned from the EVD following the hemorrhagic event.~The study will be performed a single site with up to 30 subjects who meet the inclusion and exclusion criteria for the study. Subjects will be evaluated every 30 days for the first 90 days following eShunt Implant deployment with standard neurological evaluation appropriate for patients with communicating hydrocephalus. In addition, follow-up will occur at 180 days, 12 and 24 months post-operatively and will include imaging in addition to the standard neurological evaluation.
The eShunt™ System is a minimally invasive method of treating communicating hydrocephalus. The eShunt System includes a proprietary eShunt Delivery System and the eShunt Implant, a permanent implant deployed in a minimally invasive, neuro-interventional procedure. The eShunt Implant is designed to drain excess cerebrospinal fluid (CSF) from the intracranial subarachnoid space (SAS) into the venous system.
