INFUSION CATHETER

摘要

INFUSION CATHETER A catheter comprising an elongated flexible tube having an elongated passage extending axially through the tube between proximal and distal openings and a helically wound wire engaging the peripheral wall of the tube and providing a portion of the peripheral wall with an uneven contour. The tube includes a radiopaque marker at the distal end of the catheter. The radiopaque marker is molded from a biocompatible metal powder and a thermoplastic binder. The catheter is adapted for use with an angiography catheter, and it is configured to provide automatic orientation of the distal end portion of the catheter as such distal end portion emerges from the distal opening of the angiography catheter.
