摘要

A perfusion catheter for use in open heart surgery having inner and outer concentric balloons adjacent to the distal end of the catheter wherein the inner balloon is a cuff that may be inflated by a syringe using either air or liquid via a second lumen in the catheter, the outer balloon self-inflating when perfusion liquid flows through the catheter, and a third and lumen of the catheter to monitor the infusion pressure at the distal end of the catheter, is disclosed.
