This is a prospective, non-randomized, open-label, multi-center, pilot study in subjects with normal pressure hydrocephalus for whom a traditional cerebrospinal fluid (CSF) shunt implant is indicated.~Up to 10 subjects will receive the eShunt Implant at up to three investigational sites. It is anticipated that up to 45 patients may need to be enrolled (consented) in order to result in 10 subjects who qualify according to the inclusion/exclusion criteria. Subjects will return for five follow-up visits in the first year and then continue to attend visits every six months until the study is closed or up to five years post-implantation.~The study objectives are to demonstrate safety of the eShunt Procedure, as well as demonstrate safety and efficacy of the eShunt Implant in a small sample of patients. Subjects will be followed long-term; primary analysis results will be used to support additional studies.
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 System is intended to shunt cerebrospinal fluid from the intracranial subarachnoid space to the venous system for the treatment of patients with normal pressure hydrocephalus, reducing disability due to symptoms including one or more of gait disturbance, cognitive dysfunction and urinary incontinence.
