| Abstract: |
A method for treating a patient sustaining an acute ischemic stroke in the brain. The brain has a blood circulatory system including a torcular Herophili and first and second transverse venous sinuses adjoining the torcular Herophili. The method comprises at least partially occluding the first and second transverse venous sinuses in first and second locations, respectively, adjacent to the torcular Herophili to partially obstruct venous blood drainage while permitting some antegrade venous blood flow from at least one of the transverse venous sinuses. A flow of the patient's arterial blood is introduced into at least one of the transverse venous sinuses to provide a substantially continuous retrograde blood flow into the venous side of the brain of the patient to overcome the lack of arterial blood flow for a period of time until the patient exhibits at least some resolution of ischemic brain symptoms.

What is claimed:
1. A method for treating a patient sustaining an acute ischemic stroke in the brain, the brain having a blood circulatory system including a torcular Herophili and first and second transverse venous sinuses adjoining the torcular Herophili, the method comprising at least partially occluding the first and second transverse venous sinuses in first and second locations respectively adjacent to the torcular Herophili to partially obstruct venous blood drainage while controlling the degree of said at least partially occluding the first and second transverse venous sinuses to permit some antegrade venous blood flow from at least one of said transverse venous sinuses and introducing a flow of the patient's arterial blood into at least one of said transverse venous sinuses distal to said locations to provide a substantially continuous retrograde blood flow into the venous side of the brain of the patient to overcome the lack of arterial blood flow for a period of time until the patient exhibits at least some resolution of ischemic brain symptoms.
