Abstract
Abstract Methods are provided for partial aortic obstruction for cerebral perfusion augmentation in patients suffering from global or focal cerebral ischemia. Alternatively, the methods can be used to partially obstruct aortic blood flow to condition the spinal cord to secrete neuroprotective agents prior to abdominal aortic aneurysm repair. Partial obstruction of a vessel can be accomplished by a device comprising an elongate catheter and a distally mounted expandable member. The expandable member may comprise one or two balloons. Other medical devices, such as an angioplasty, stent, or atherectomy catheter, can be inserted distal the expandable member to provide therapeutic intervention.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
1 . A method for increasing cerebral blood flow, comprising the steps of: advancing a catheter into the descending aorta, the catheter having a proximal region, a distal region, and an expandable member mounted on the distal region; locating the expandable member in the descending aorta; expanding the expandable member to partially obstruct blood flow in the aorta during systole and diastole; measuring a physiologic parameter; and adjusting the expansion of the expandable member based on the measured physiologic parameter, wherein cerebral blood flow is increased without substantially increasing cerebral blood pressure.
Claim 2
Dependent Claim
