<p>A cannula is provided particularly for use in connection with aortic perfusion. In its simplest form, it comprises a perfusion cannula with a main channel which is fluidly connected at one end to an intra-aortic portion of the cannula and, at the other end, is fluidly connected to the aortic perfusion line of a cardiopulmonary bypass. A first side port is adapted for fluid connection to an extra-aortic pump or to an intra-aortic balloon pump. The other end of the first port is in fluid connection with the intra-aortic portion of the cannula. This arrangement permits the insertion of the intra-aortic balloon pump through the first port, into the intra-aortic portion of the cannula, and beyond into the descending aorta. A blood pressure port is fluidly connected to a blood pressure monitoring tube said tube is located within the intra-aortic portion and extends therein to a pressure point upstream of the distal end of the portion. The other end of the tube is adapted for connection to a blood pressure measuring or monitoring device. <IMAGE></p> |
