Equipment used in diagnostic cardiac catheterizaiton

Left and Right Judkins Catheters

 * Constructed from polyethylene or polyurethane with a fine wire braid within the wall to allow advancement and directional control and to prevent kinking.
 * The left Judkins catheter: This catheter is preshaped to allow entry into the left coronary ostium from the femoral approach with minimal catheter manipulation.
 * A preformed left Judkins catheter can also be used from the left brachial or radial artery, but a catheter with 0.5 cm less curvature than required for the femoral approach is generally better suited for coronary cannulation.
 * The right Judkins catheter: This catheter is shaped to permit entry into the right coronary artery (RCA) with a small amount of rotational catheter manipulation from any vascular approach.

Left and Right Amplatz
Amplatz catheters can be used for the femoral or brachial approach to coronary arteriography.
