Abstract
A novel ventricular catheter designed to reduce CSF shunt obstruction is disclosed comprising a tip using a membrane without any opening and capable of filtering the CSF. When the CSF flows through the membrane, neither tissue (choroid plexus, blood cells, tumor cells, suctioned ependymal tissue) nor proteins can break through the membrane, making this ventricular catheter capable of preventing obstruction from tissue invasion but also preventing clogging from protein precipitation, coagulation or flocculation along the downstream shunt system.
