Abstract
A catheter for cardiac procedures includes a generally C-shaped distal end which roughly conforms to the shape of an aortic arch. The catheter is made of a flexible material and includes a distal portion having a proximal section connected to an intermediate section at approximately 135 degrees. The distal most section attached to the intermediate section is generally perpendicular to the intermediate section and consists of a double or reverse curve. The structure allows the catheter to be utilized to enter either left or right ostia without catheter exchange by rotation of the catheter around its axis.
