Abstract

This invention relates to a shunting device adopted in the intracranial shunting surgical operation for the treatment of hydrocephalus. It is comprised of a thin film and a ventricular tube to be implanted into the cranium of a patient with hydrocephalus, which will bypass the intraventricular cerebrospinal fluid (CSF) in the brain of such a patient, and thus maintain a normal pressure inside the cranium for the treatment of hydrocephalus.

Claims

1. An intracranial shunting tube consisting essentially of a thin film and a ventricular tube, said ventricular tube having an open top end, a closed bottom end, a central axis, and a plurality of side holes defined therethrough adjacent said closed end, said thin film being provided at said open end of said ventricular tube so as to extend radially outwardly from said open end, the shunting tube being implantable into the brain of a patient with hydrocephalus so as to bypass ventricular cerebrospinal fluid (CSF) to the subdural space on the surface of the brain of the patient and shunt the CSF fluid from the overdistented ventricle of the patient in order to maintain a normal intracranial pressure.

2. An intracranial shunting tube as in claim 1, wherein said ventricular tube is formed principally from crosslinked poly-2-hydroxyethyl methracylates hydrogel material.
