The antegrade cardioplegia cannulae are used as infusion cannulae for cardioplegic solutions. The cardioplegic solution is perfused through the aortic root into the coronary arteries. They may also be used as drainage and deairing cannulae for left ventricular relaxation and aortic arch deairing during cardiac bypass.
With the retrograde cardioplegia cannula, the solution is perfused through the coronary sinus.
MAQUET offers a range of different antegrade cardioplegia cannulae. They may all be used as both infusion cannulae for cardioplegic solution and as ventilation cannulae.The innovative design ensures excellent handling. The proximal vent line feature allows a clear view of the operative field.
The antegrade cardioplegia cannula has a soft flexible PVC tip which is attached to a flexible connecting tube made of transparent PUR. The cardioplegia cannula is supplied with a stainless steel trocar needle and features an innovative security system: on removal, the steel tip of trocar retracts completely into a protective sheath thus preventing injury. As the needle is removed from the cannula there is minimal blood loss. Luer-lock connectors for quick connection, a soft cannula attachment flange, and a transparent ergonomic grip offer safety for the patient and ease of handling for the operator.
The retrograde cardioplegia cannula with automatically inflating balloon is used for perfusing cardioplegic solutions via the coronary sinus. The soft balloon is automatically filled and inflated by the flow of cardioplegic solution to seal and secure the cannula tip in position within the coronary sinus. The pressure at the cannula tip can be monitored at any time using the measuring lumen. In the case of the manually inflating model, the balloon is filled manually via a third lumen. Both versions, the automatic and the manual, are available with flexible or rigid stylet to simplify insertion and positioning of the cannula tip in the coronary sinus. Standard luer-lock connectors for quick connection and a seam band to securely hold the purse-string suture tourniquet ensure secure attachment and easy handling of the cannula.
