Device for the treatment of hydrocephalus
First Claim
1. A cerebrospinal fluid shunt system comprising brain ventricle catheter means for insertion into the brain ventricle so as to drain cerebrospinal fluid from said brain ventricle;
- sinus sagittalis catheter means for insertion into the sinus sagittalis for feeding said cerebrospinal fluid into sinus sagittalis;
shunt main body means connected at one end thereof to said brain ventricle catheter means and at another end thereof to said sinus sagittalis catheter means for providing fluidic communication between said brain ventricle catheter means and said sinus sagittalis catheter means; and
tubular flow passage restricting means defined within said shunt main body defining a resistance to flow of 8-12 mm Hg/ml/min.

Abstract
A cerebrospinal fluid shunt system comprises a brain ventricular catheter for insertion into the brain ventricle so as to drain cerebrospinal fluid from the brain ventricle. The system also comprises a sinus sagittalis catheter for insertion into the sinus sagittalis for feeding the cerebrospinal fluid into sinus sagittalis. A shunt main body is connected at one end thereof to the brain ventricle catheter and at another end thereof to the sinus sagittalis catheter. The shunt main body can provide fluidic communication between the brain ventricle catheter and the sinus sagittalis catheter. The system further comprises a tubular flow passage restricting member defines within the shunt main body. The tubular flow passage restricting member defines a resistance to flow of 8-12 mm Hg/ml/min.
