ENDOVASCULAR CEREBROSPINAL FLUID SHUNT

摘要

An implantable shunt device for draining cerebrospinal fluid from a patient's subarachnoid space. The device includes a shunt having opposed first and second ends. A one-way valve is located at the first end of the shunt. A helical tip is disposed at the second end. The helical tip is constructed to penetrate a sinus wall of the patient. Upon implantation, a hollow passageway extends between the helical tip and one-way valve such that fluid can be drained through the helical tip and out through the valve. The endovascular cerebrospinal fluid shunt of the present invention can be placed into a patient percutaneously via a catheter inserted into the venous system of the body through a needle hole, without the need for open surgery and the skin incisions required with current shunt devices. The device also allows for more physiologic drainage of cerebrospinal fluid since the device is shunting cerebrospinal fluid into the same cerebral venous system that occurs naturally in normal people.
