Abstract
A catheter adapted for placement within a living anatomy, such as the human coronary arterial system, comprises a proximal portion, a first arcuate portion, a second arcuate portion, and a distal tip. The catheter is shaped so that with the distal tip engaged in the coronary ostium, the ellipsoidal shaped second arcuate portion is in contact with the contralateral wall of the aorta, the catheter thus resisting forces tending to displace the distal tip from the ostium.
