Patent AT-E399577-T1: [Translated] FLUID DRAIN DEVICE FOR TREATING HYDROCEPHALUS
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. One end of each of the catheters ( 15, 18 ) is then connected to a respective end of the shunt body member ( 10 ), and a second end of each catheter is inserted in the right ventricle ( 21 ) and in the sinus sagittalis system ( 22 ), respectively, via holes bored in the scull ( 19 ).
