ABSTRACT:
Catheters are provided having a plurality of vanes external to a central core serving as channels for microbubbles. A track may be provided having grooves in which one of the vanes passes, which track provides additional microbubbles, so as to allow for following the movement of the catheter and track by ultrasonic imaging. The catheter provides for reduced abrasion, as well as ease of following the movement of the catheter through the patient's vessels.
