摘要

A blood perfusion balloon catheter is provided. The perfusion catheter includes an elongate tubular shaft having a proximal portion and a distal portion and a plurality of toroidal-shaped inflatable balloons laced through the distal portion of the tubular shaft, the balloons creating a blood flow lumen when they are inflated. The perfusion catheter may also include a cylindrical sheath attached to the balloons.
