Abstract
A balloon suction catheter may be used to remove clots and increase blood flow to obstructed vessels such as a cerebral artery in a stroke patient. The catheter may be used to apply suction on the clot while providing flow arrest, embolic protection, and optionally flow reversal. The same catheter may also be used to provide for a flow modulation procedure known as post-conditioning to potentially reduce any damage from the sudden reintroduction of blood flow reperfusion injury.
