Abstract:
A method for administering cardioplegia, comprising the steps of:providing a substantially rigid cannula having proximal and distal ends, and a proximal and a distal region, a balloon occluder mounted on the distal region and communicating with an inflation lumen extending proximal from the occluder, a port on the cannula proximal the balloon, the port communicating with a first lumen which extends proximally from the port;making an incision in the aorta;inserting the distal end of the cannula and the occluder through the incision in the aorta;expanding the occluder to occlude the aorta downstream of the infusion port; andinfusing cardioplegia solution through the port,wherein the occluder isolates the ascending aorta from peripheral circulation without substantial migration within the ascending aorta.
