摘要： MVO is treated by introducing injectate into blood vessels affected by MVO at precise flow rates, while blocking retrograde flow, such that the natural pumping of the heart aids in forcing the injectate into the affected microvessels. Monitoring pressure distal of an occlusion balloon is used to determine treatment effectiveness and heart health.

摘要： An ultrasound catheter has an elongate flexible catheter body having a lumen extending longitudinally therethrough, and an ultrasound transmission member extending longitudinally through the lumen of the catheter body. The ultrasound transmission member has a proximal end that is coupled to a separate ultrasound generating device, and a distal tip that is attached to the distal end of the ultrasound transmission member and which is located at the distal end of the catheter body. The ultrasound transmission member is directly attached to the catheter body and/or to a guidewire tube either directly or via an attachment device. The catheter has an additional radiopaque marker positioned on the distal end the catheter.

摘要： A system of devices for treating an artery includes an arterial access sheath adapted to introduce an interventional catheter into an artery and an elongated dilator positionable within the internal lumen of the sheath body. The system also includes a catheter formed of an elongated catheter body sized and shaped to be introduced via a carotid artery access site into a common carotid artery through the internal lumen of the arterial access sheath. The catheter has an overall length and a distal most section length such that the distal most section can be positioned in an intracranial artery and at least a portion of the proximal most section is positioned in the common carotid artery during use.

摘要： A hydrodynamic catheter includes a catheter body with a catheter lumen and an infusion tube extending within the catheter body, the infusion tube configured for coupling with a fluid source near the catheter proximal portion. An inflow orifice and an outflow orifice are positioned at locations along a catheter body perimeter. A fluid jet emanator is in fluid communication with the infusion tube, where the fluid jet emanator includes one or more jet orifices configured to direct one or more fluid jets through the catheter lumen from near the inflow orifice toward the outflow orifice. A pivot cylinder located along the catheter body perimeter is positioned distal relative to one or more of the fluid jet emanator, the inflow orifice, or the outflow orifice.
