摘要：
An extracorporeal circulation catheter has three independent channels and an expandable balloon at one end of the catheter. The first channel allows for delivery of blood to a patient in an amount sufficient to maintain the patients metabolism and perfusion throughout the treatment or surgery. The second channel is integrated into the wall of the first channel and is suitable for delivering a fluid (e.g., for cardioplegia) to the heart. A third channel is integrated into the wall of the first channel and is suitable 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. The first channel accounts for at least about 70% of the total channel volume.
