A catheter for retroprofusing a venous junction formed by first, second and third veins, includes an elongate tube having a plurality of channels including a through-lumen extending between a proximal end and a distal end. A proximal balloon is inflatable to partially occlude the third vein, while a distal balloon is inflatable to partially occlude the second vein. An operative region of the catheter between the first and second balloons is adapted to pressurize the venous junction with arterial blood to produce retrograde blood flow in the first vein.

[ We claim:] [1.] A catheter for a retroperfusing a venous junction defined by a first vein providing normal blood flow into the junction, and a second and third vein each providing normal blood flow away from the junction, the catheter comprising:an elongate tube having an axis extending between a proximal end and a distal end;portions of the tube defining a plurality of channels, including a through-lumen extending from the proximal end through the distal end of the tube;a first occlusion device disposed in proximity to the distal end of the tube and adapted to at least partially occlude the third vein;a second occlusion device disposed in proximity to the first occlusion device and adapted to at least partially occlude the second vein with the venous junction disposed between the first occlusion device and the second occlusion device; anda retroperfusion lumen included in the channels and having an outlet between the first occlusion device and the second occlusion device, the retroperfusion lumen being adapted to receive arterial blood or pharmacological agents under pressure in order to induce retrograde blood flow in the first vein.
