ABSTRACT:
A guiding catheter adapted to be passed through the right side of the heart into the pulmonary artery and comprising a catheter body having at least first and second lumens extending longitudinally in the catheter body and a port extending from the first lumen to the exterior of the catheter body. The port is between the ends of the catheter and is in the right heart when the catheter is in use. An elongated stiffening element is locked within the second lumen and extends from a location on the proximal side of the port to a location on the distal side of the port. The stiffening element is flexible, but it is sufficiently stiff to cause the catheter to be gently curved along the stiffening element without forming a kink when the catheter is in use. The first lumen is adapted to have an inner catheter passed through it and out of the port into the right heart.
