Coronary Perfusion Cannulae are used for direct cannulation to supply cardioplegic solutions to the coronary arteries during heart operations with an external bypass. Maquet offers both self-inflating balloon cannulae and cone tip cannulae for coronary perfusion.

Self-Inflating Balloon Cannulae

With the Maquet self-inflating balloon cannulae, balloon inflating is automatic and continuous and results from the infusion of cardioplegic solution. A retaining suture is not normally needed.

The soft balloon tip is ideally positioned directly in the left coronary ostia. The overall balloon length is such that the tip does not normally reach the bifurcation of the coronary vessels.

The self-inflating balloon cannulae are available in several configurations:

  • Straight or right angle
  • Soft or slightly hardened tips
  • A choice of a proximal end fitting (to take a 1/4" connector) or a female Luer fitting

The use of a right angle tip cannula ensures that the cannula body does not obstruct the operative site. Cannula external diameters range from 2.1 to 4.0 mm with balloon diameters (not inflated) of 4 to 9 mm.

Cone Tip Cannulae

Maquet Cone Tip Cannulae are also used for insertion in the coronary arteries. A retaining suture is needed. The rigid cone makes insertion easy, and the use of a right angle cannula provides an unobstructed operative site for the surgeon.

  • Available in three external diameters from 3 mm to 4 mm
  • Cone diameters from 5 mm to 7.5 mm
  • A choice of a proximal end fitting (to take a ¼” connector) or a female Luer fitting
