A noncannulating coronary perfusion cannula.
A noncannulating cannula was devised to avoid trauma to the coronary ostia and secondary ostial stenosis. The cannula achieves a seal with the aortic wall through the use of bulbous silicone gel-filled tip. The same cannula has effectively perfused the right and left ostia and previously placed aorta-coronary bypass grafts with one exception, in which calcification of the aortic wall prevented a satisfactory seal.
