Abstract
A single, multichannel catheter is useful for extracorporeal circulation of blood to a patient undergoing cardiovascular treatments or surgery. The catheter has three independent channels and an expandable balloon at one end of the catheter. The first channel is largest and allows for delivery of blood to a patient in an amount sufficient to maintain the patient's metabolism and perfusion throughout the treatment or surgery. The second and third channels are smaller and integrated into the wall of the first channel. The second channel is for delivering a biologically active fluid to the heart and/or venting the left heart. The third channel is for delivering a fluid to the balloon for its expansion when positioned in the ascending aorta to occlude the flow of blood to the heart. One or more perfusion openings may be located in the descending aorta.
