Indications, Safety, and WarningsIndications for UseThe MīAR™ cannula is intended for use during cardiopulmonary bypass for the delivery of cardioplegia for up to 6 hours. The cannula may also be used to aspirate air from the aorta at the conclusion of the bypass procedure. It is indicated for use during cardiac surgery for median sternotomy or minimally invasive (mini-sternotomy or right thoracotomy) access using direct visualization techniques.ContraindicationsThis device is not intended for use except as indicated above.WarningsIf the introducer needle is removed from the cannula before placement into the aorta, use caution when reinserting the introducer to prevent cutting or gouging the inner surface of the cannula or tip. Do not reinsert the introducer needle into the cannula once removed after placement into the aorta.Utilization of this cannula in conjunction with aortic cross clamping for perfusion of the coronary arteries may not result in adequate perfusion of the heart if the aortic valve is incompetent or the coronary arteries have extensive disease and/or occlusions or are anomalous.PrecautionsNote: Proper surgical procedures and techniques are the responsibility of the medical professional. The described procedure is furnished for information purposes only. Surgeons must evaluate the appropriateness of the procedure based on their own medical training and experience, the type of surgical procedure, and the type of delivery and suction systems utilized.When infusing cardioplegia solution, use the lowest possible pressures consistent with surgical techniques to minimize hemolysis or damage to the vessels.When removing the cannula, withdraw it from the aorta before tightening the purse string suture to prevent catching the suture in the side holes or slots of the cannula tip.This device was designed for single patient use only.
