Abstract
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.
