    摘要： According to the present invention, an artificial lung in a circulation apparatus can be monitored and be maintained in a safe condition without manual assistance. Therefore, as an extracorporeal circulation mode starts, it is determined first whether or not gas exchange of the artificial lung is carried out within a normal range, based on oxygen concentration which is detected by an oxygen sensor positioned at a downstream place in the artificial lung. If the gas exchange is carried out within the normal range, an estimated value for gas supply volume of a gas blender is maintained. When oxygen concentration exceeding the normal range is detected, the gas blender is controlled so as to revise the gas supply volume downward. In addition, when oxygen concentration falls below the normal range, the gas blender is controlled so as to revise the gas supply volume upward.

    摘要： Some embodiments of a system for treating heart tissue can include a catheter device that provides a user with the ability to perform a number of heart treatment tasks (before, during, and after a cardiac surgery or a percutaneous coronary intervention). In particular embodiments, the catheter device can be used to (i) precondition heart muscle tissue before the heart is isolated from the circulatory system, (ii) deliver cardioplegia into the coronary sinus during the cardiac surgery when the heart is isolated from the circulatory system, and (iii) control the blood flow through the heart after the heart is reconnected with the circulatory system. In some embodiments, the catheter device can perform some or all of: (i) intermittently occluding the coronary sinus, (ii) delivering a treatment fluid into the coronary sinus, and (iii) monitoring a flow rate of blood passing from the coronary sinus to the right atrium.
