Catheter for the right coronary artery

A catheter for the right coronary artery, the catheter comprising:

• a substantially straight proximal shaft section having a proximal end and a distal end;
• and a distal shaft section having a proximal end and a distal end, the proximal end of the distal shaft section connected to the distal end of the proximal shaft section, the distal shaft section including a primary curve proximate the distal end, a secondary curve located proximal of the primary curve, a substantially straight transition portion disposed between the primary curve and the secondary curve, and an oppositely-facing tertiary curve having a proximal end and a distal end, the proximal end of the tertiary curve connected to the distal end of the proximal shaft section and the distal end of the tertiary curve connected to the proximal end of the secondary curve, wherein the length from the distal end of the distal shaft section to the apex of the secondary curve is approximately equal to the distance from the ostium of the right coronary artery to the opposite aortic wall thereby providing increased back-up support utilizing the opposite aortic wall, and further wherein the tertiary curve has an arc angle of less than about 90 degrees such that torque may be readily transmitted from the proximal shaft section to the support arm thereby facilitating controlled tip manipulation.
