ABSTRACT:
A radial guiding catheter comprising a first straight leg connected to a first curve. The first curve has an angle such that the first curve can be disposed just proximal to the coronary ostium. The first curve is connected to a second straight leg. The second straight leg is connected to a second curve such that the second curve can be disposed within the aortic valve. The second curve has a direction opposite the first curve. The second curve is connected to a third straight leg. The distance between the second straight leg and the third straight leg is sufficient to cause the distal end of the first straight leg to engage the left coronary artery. The third straight leg is connected to a third curve, the third curve having a direction opposite the second curve such that the third curve is disposed along the ridge of the brachial artery. The third curve is connected to the forth straight leg such that the catheter provides greater back up support with the contralateral wall of the aorta just distal to the aortic valve.
