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.

Abstract: The present invention relates to the construction of thin-walled balloon catheters where navigability, low cross-sectional profile, and low inflation and deflation times are desired. Structural reinforcement of inflation lumen utilizes a soft, flexible, permeable material to fill the fluid channel to maintain patency of the lumen.

Abstract: New devices, systems, and methods are disclosed for preventing, treating, and/or at least minimizing ischemia and/or reperfusion injury by restoring and/or modulating blood flow, particularly in the cerebral vasculature where blood vessels are narrow and tortuous. These devices, systems, and methods make it possible for a clinician to adequately and systematically restore blood flow to ischemic tissue while simultaneously modulating the blood flow to minimize reperfusion injury. New thrombectomy devices and systems, which, for example, expand with greater radial force, further enable improved binding with clots and restoration of blood flow.
