Abstract
A system for determining orientation of a distal end of a catheter. The system includes a flexible shaft having a first lumen, a second lumen, a third lumen, a fourth lumen, a first orientation pin and a second orientation pin. The first orientation pin is received within the third lumen and the second orientation pin is received within the fourth lumen. The flexible shaft includes a cross-sectional dimension and the third lumen and the fourth lumen include longitudinal axes that are located on the same half of the cross-sectional dimension of the catheter. The second lumen includes an exit port for exposing at least a portion of the second lumen of the cap portion and a ramp. A distal end of the flexible shaft is made of material permeable to ultrasound signals and the orientation pins include one or more materials that are non-permeable to ultrasound signals.
