Abstract
The invention relates to a cardiopulmonary bypass pump that can be used with medication to put the heart into asystole or near asystolic status. This gives the physician enough time to perform diagnostic and/or therapeutic procedures and also allows the diseased heart to recover from ischemic insults without additional hemodynamic stress, and also facilitates certain cardiac procedures.The patent describes equipment used in conjunction with medication to temporarily replace the function of the heart and to allow the heart to survive with minimal oxygen supply for hours or days, and for the heart to recover from ischemic or other insult or other damage without being subjected to a heavy working load. The invention provides a means to stop blood flow to the heart for a relatively long period of time, thereby allowing the performance of certain procedures that require coronary artery blockade. It also allows the heart to stop contracting, which may result in safer and easier performance of some procedures.A pump is used to drain blood from the patient's veins into a gas exchanger. The exchanger oxygenates the blood and removes carbon dioxide from the blood, then the pump pumps the blo…
