The present invention pertains to a perfusion cannula for insertion into an artery. The perfusion cannula comprises a main channel fluidly connected to an intra-aortic portion of the cannula. The main channel is also adapted for fluid connection to an aortic perfusion line of a cardiopulmonary bypass. The intra-aortic portion has a proximal end adjacent the main channel and a distal end remote from the main channel. There is also provided a first side port which can be fluidly connected to an intra-aortic balloon pump at a remote end and in fluid connection with the intra-aortic portion at a near end. A blood pressure port is also provided which is fluidly connected to a blood pressure monitoring tube. The tube is located within the intra-aortic portion and extends therein to a pressure point which is 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. The present invention provides a means whereby an intra-aortic balloon, in conjunction with an intra-aortic balloon pump, can be used to assist the failing heart. |
