The fluid flows in and around the brain and spinal cord to cushion and protect them from injury (Fig. 1). Veins at the top of the head absorb CSF into the bloodstream at the rate of about one ounce per hour. NPH occurs when the normal volume of CSF is not absorbed fast enough, cau...

A cerebrospinal fluid shunt system comprises a brain ventricle catheter () to insert into the brain ventricle () so as to drain cerebrospinal fluid from the brain ventricle, a sinus catheter () to insert into the sinus sagittalis system () for feeding the cerebrospinal fluid into the sinus sa...
A cerebrospinal fluid shunt system comprises a brain ventricle catheter ( 15 ) to insert into the brain ventricle ( 21 ) so as to drain cerebrospinal fluid from the brain ventricle, a sinus catheter ( 18 ) to insert into the sinus sagittalis system ( 22 ) for feeding the cerebrospinal flu...
A fluid shunt system for the treatment of hydrocephalusA cerebrospinal fluid shunt system comprises a brain ventricle catheter (15) to insert into the brain ventricle (21) so as to drain cerebrospinal fluid from the brain ventricle, a sinus catheter (18) to insert into the sinus sagittalis ...
A mechanical-electrical model is suggested based on the brain physiology and blood circulation. In the proposed model, hydrocephalus is modeled with an incremental resistance () and hydrocephalus shunt, which is a low resistance path to drain the accumulated CSF in the brain ventricles, is modeled...
Alteration of brain viscoelasticity after shunt treatment in normal pressure hydrocephalus The symptoms of NPH may be relieved by surgically implanting a ventriculoperitoneal shunt to drain excess cerebrospinal fluid. However, the pathogenesis of ... Florian,Baptist,Freimann,... - 《Neuroradiology》 被...

5.The shunt according to claim 4, wherein said at least two lumens comprise:a fluid conduit that functions as a conduit for the at least one occlusion resistant agent;and a drainage conduit that functions as a conduit for CSF drainage. ...
A new minimally-invasive endovascular cerebrospinal fluid shunt has been developed (CereVasc eShunt) to mimic arachnoid granulation function. This implant is intended to be deployed via femoral transvenous approach across the inferior petrosal sinus dura mater into the cerebellopontine angle cistern. ...
