Method and apparatus for differentially perfusing a patient during cardiopulmonary bypass
First Claim
1. An aortic catheter comprising:
- a catheter shaft having an outer tubular member and an inner tubular member, said inner tubular member slidably disposed within said outer tubular member;
an occlusion member expandable from said catheter shaft;
an arch lumen defined by an annular space between said inner and outer tubular members extending at lest in part along the length of said catheter shaft and having at least one distal arch opening, a proximal arch lumen connector in fluid communication with said arch lumen and configured for connection to a CPB machine;
a corporeal lumen having at least one distal corporeal opening positioned distal to said occlusion member, a proximal corporeal lumen connector in fluid communication with said corporeal lumen and configured for connection to a CPB machine; and
a suction source in communication with a port in the catheter shaft proximal to said occlusion device.

Abstract
The present invention provides methods, systems and devices for performing cardipulmonary bypass (CPB), cardioplegic arrest, suction of fluid from the aorta to remove embolic or other fluid from the general circulation and the selective segmentation of the arterial system to perform differential perfusion eliminating hypoperfusion. An aortic catheter having an arch lumen which extends at least in part along the length of the catheter shaft has a proximal opening coupled to a CPB machine and a distal arch opening. A corporeal lumen extends at least in part along the length of the catheter shaft and has a proximal opening coupled to a CPB machine and a distal corporeal opening. A suction lumen extends at least in part along the length of the catheter shaft and has a proximal suction opening coupled to a suction source and a distal suction opening residing in the aortic lumen of a patient.
