ABSTRACT:
A medical pump device is constructed so that a pulsation force is applied to the blood in the vicinity of an artery, which is reconstructed after a bypassing operation has been completed, so as to compensate for a deviation of an actual wave form of a blood flow in the vicinity of the reconstructed artery from a normal wave form thereof. The medical pump device is capable of minimizing the possibility of occurrence of a late obturation in an artery which is reconstructed after a reconstruction operation has been completed, and improving a rate of keeping open the reconstructed artery.
