  • Patent number: 7118548
    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 defined within the shunt main body. The tubular flow passage restricting member defines a resistance to flow of 8-12 mm Hg/ml/min.

  • 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.

  • Publication number: 20040073154
    Abstract: The invention provides means by which access to the intracranial compartment is completely sealed from the skin and the scalp tissues, which makes it possible to change the drain when necessary without bringing the drain in the contact with the scalp. It also provides an improved ventricle draining system supporting a better fixation of the drain to avoid the drain from sliding. The drain comprises a fixture with a conduit defining passage through the fixture, the fixture being provided with fastening means for attachment of the fixture to an aperture in the cranial bone, a seal for sealed engagement with a catheter inserted in the fixture, and fastener for securing the catheter to the fixture.
