Abstract

A medical device for providing retrograde venous perfusion to the cerebral vasculature for treatment of global or focal cerebral ischemia is disclosed. The device includes a catheter having an infusion port at its distal end, venous drainage port(s), and an expandable occluder disposed between the infusion port and drainage port(s). The catheter is adapted for insertion in the superior vena cava or the internal jugular vein. The catheter is attached proximally to a pump and an oxygenator with or without a cooling system. Alternatively, the device comprises two catheters, each having a lumen communicating with a distal infusion port and an occluder mounted proximal to the port. The catheters are adapted for insertion in the internal jugular veins distal to jugular venous valves. Methods of using the devices to provide retrograde venous perfusion and isolated cerebral hypothermia are disclosed.
