Abstract
A perfusion cannula for insertion into an artery having a main channel fluidly connected to an intra-aortic portion and in fluid connection with an aortic perfusion line of a cardiopulmonary bypass. The cannula includes a first side port to which an extra-aortic balloon pump may be connected or through which an intra-aortic balloon pump may be inserted. Also, there is a blood pressure port which can be connected to a blood pressure monitoring device without removal of the cannula.
Claims21
A perfusion cannula for insertion into an artery, a main channel fluidly connected to an intra-aortic portion of said cannula, said main channel in fluid connection with an aortic perfusion line of a cardiopulmonary bypass, said portion having a proximal end adjacent said main channel and a distal end remote from said main channel, a first side port adapted for fluid connection to a balloon pump at a remote end and in fluid connection with said portion at a near end, a blood pressure port fluidly connected to a blood pressure monitoring tube, said tube being within said portion and extending to a pressure point upstream of said distal end, said tube being adapted for connection to a blood pressure monitoring device and a girdle surrounding a part of said artery, said cannula extending through said girdle into said artery.
A method of introduction of a cannula into an aortic artery, said cannula comprising a main channel fluidly connected to an intra-aortic portion of said cannula, said main channel in fluid connection with an aortic perfusion line of a cardiopulmonary bypass, said portion having a proximal end adjacent said main channel and a distal end remote from said main channel, a first side port adapted for fluid connection to a balloon pump at a remote end and in fluid connection with said portion at a near end, a blood pressure port fluidly connected to a blood pressure monitoring tube, said tube being within said portion and extending to a pressure point upstream of said distal end, said tube being adapted for connection to a blood pressure monitoring device,
- said method comprising making an incision in a wall of said artery, inserting said cannula through said incision into said artery, clamping said cannula to prevent blood loss, and inflating said cannula.
