Abstract
The present invention is directed to methods and devices for accessing a cerebral vessel. The system includes a support catheter having a balloon, which can be advanced into small and tortuous vessels. By advancing the support catheter nearer to the obstruction then can be achieved with conventional guide catheters, the support catheter reduces the likelihood vessel compression and collapse when manipulating a working catheter. The balloon may be used to temporarily stop blood flow.
