Abstract
A guiding catheter system employs a flexible shaft having a preformed bend at a distal end. An ultrasound transducer is mounted proximal to the pre-formed bend. The ultrasound transducer has a field of view directed to a distal tip of the guiding catheter. The guiding catheter includes an open lumen adapted for the introduction of payloads through the catheter system. The guiding catheter system can be used to direct a smaller guiding catheter or guide wire into a destination vessel from a heart chamber. In one application, the guiding catheter system is used to introduce a guiding catheter into the coronary sinus ostium from the right atrium.
