The CardioGard Emboli Protection Cannula combines the function of a standard arterial cannula with an added suction mechanism to capture debris that may result from cardiac surgery. The CardioGard Emboli Protection Cannula is intended for perfusion of the ascending aorta during short term (<6 hours) cardiopulmonary bypass (CPB) procedures. The CardioGard suction lumen is intended for the removal of particulate emboli during surgical procedures that require CPB.

The CardioGard Emboli Protection Cannula (CardioGard Cannula) is a sterile, single-use, disposable double lumen arterial cannula. The CardioGard Cannula features a tip configuration that diffuses oxygenated blood from the heart-lung machine into the ascending aorta through the Cannula Outlet, while also aspirating blood and embolic matter through the Suction Lumen Inlet. The flow rates through the two cannula lumens are carefully controlled so that emboli are suctioned back to the heart-lung machine for filtration while still enabling sufficient blood flow to the patient.

The CardioGard Emboli Protection Cannula, shown below, is a disposable 24 French double lumen arterial cannula. The cannula functions to deliver oxygenated blood to the heart during procedures requiring cardiopulmonary bypass (CPB), while at the same time suctioning blood and embolic matter away from the surgical field. The arterial cannula is inserted centrally in the ascending aorta.
