Intra-aortic dual balloon driving pump catheter device

An intra-aortic dual balloon driving pump catheter device, which comprises:

• a catheter;
• a first balloon and a second balloon, respectively surrounding the catheter, being arranged successively along the longitudinal direction of the catheter, wherein the first balloon is a counterpulsation balloon, being placed at the distal end of the catheter, and the second balloon is a valve balloon, being placed immediately adjacent to the proximal end of the first balloon and is closer to the proximal end of the catheter than the first balloon;
• a monitoring part, for monitoring the cardiac cycle and the arterial pressure of the catheter end;
• air pumps, respectively associated with the first balloon and the second balloon, for supplying and withdrawing air;
• a first intake pipe and a second intake pipe, one end of which is in communication with the first balloon and the second balloon respectively, and the other end of which is in communication with the respectively associated air pump;
• a controlling part, adapted to control the air pumps to inflate and deflate the first balloon and the second balloon according to the cardiac cycle and the arterial pressure of the catheter end monitored by the monitoring part, such that the first balloon periodically inflates in diastole to occupy the space of blood in aorta, so as to push blood towards both sides of the first balloon, whereas deflates in systole to create space, so as to proactively withdraw ejecting blood from the heart, and thus increases the cardiac output;
• and the second balloon inflates in the systole to block the distal end of the aorta to prevent the blood reflux at the distal end of the aorta when the first balloon deflates, and deflates in the diastole to make the blood flow created by the inflation of the first balloon be pushed forward downstream,
• wherein the air pumps are controlled such that the second balloon deflates at the same time the first balloon inflates, whereas the second balloon inflates at the same time the first balloon deflates, so that in each cardiac cycle, the air pumps are controlled such that the second balloon deflates and inflates conversely to the synchronized inflation and deflation of the first balloon.
