Abstract
Right and left coronary catheters that are designed to be used in a transradial coronary catheterization are provided. The catheters have a proximal end, an extended body portion, and a shaped distal end with two curved portions and a tip. When advanced into the ascending aorta, the curved portions of the distal end cooperate with the aorta to engage and maintain the tip of the catheter within the selected coronary ostium during a coronary procedure. Also provided are methods of inserting the catheters into a right or left coronary artery by a transradial approach, and using the catheters in a diagnostic or interventional procedure to selectively deliver an imaging dye or tool to the coronary artery of interest.
