Abstract
Methods and devices provide for temporary partial aortic occlusion to achieve diversion of blood flow to the brain in patients suffering from cerebral ischemia. The device can include an expandable frame with a membrane mounted on a first portion of the frame. The membrane can have at least one opening. In some embodiments, the membrane has an outer region and an inner region, and an opening in the inner region. In use, the frame can expand to conform to the inner walls of the aorta and the membrane can at least partially occlude the aorta thereby increasing cerebral perfusion. The frame can include one or more anchors to aid in maintaining the device in position against the arterial blood flow pressure.
