Abstract
The Universal Coronary Catheter is a diagnostic coronary catheter which permits simultaneous visualization of the left and right coronary arteries. This is achieved by providing a stationary lumen for cannulating the left coronary artery, and an independently-movable cannula routed through an adjacent lumen for engaging the right coronary artery. The two arms are densely packed within its shaft, the lumen of for cannulating the left coronary artery being about twice the lumen of the cannula. The catheter includes individual lumens for guidewire delivery for injecting radiocontrast agent.
