  • Patent number: 6905474
    Abstract: 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 fluid into the sinus sagittalis system, a shunt body member (10) connected at one end thereof to said brain ventricle catheter and at another end thereof to said sinus catheter system to provide fluidic communication between said brain ventricle catheter (15) and said sinus catheter (18), and a flow restriction (16) defined within the shunt body member (10) to maintain a resistance to fluid flow of the shunt system of less than 8 mm Hg/ml/min, such as 2-7 or 4-6 and preferably about 5 mm Hg/ml/min. When the shunt system is implanted the shunt body member (10) is placed subcutaneously on top of the calvarium of a patient, behind the coronal suture on one of side of the sagittal suture.
