Abstract:
An aortic perfusion catheter is an apparatus that is used during surgery for acute ascending aortic dissection to reduce postoperative injuries from profound hypothermia, ischemia, and reperfusion. The apparatus may include at least one main cannula, an inflation cannula, a drainage cannula, and a balloon tamponade. The at least one main cannula helps maintain blood perfusion to the body during the procedure to reduce postoperative injuries. The inflation cannula enables the selective inflation and deflation of the balloon tamponade to facilitate the insertion and removal of the balloon tamponade along with the at least one main cannula within the descending thoracic aorta. The balloon tamponade prevents blood flow into the operative area to maintain the operative area clear during the procedure. The drainage cannula enables the drainage of blood that may escape the balloon tamponade as well as other bodily fluids.
