Fiber optic catheter with shortened guide wire lumen |
摘要 |
A fiber optic catheter has a short guide wire lumen (less than 10 cm) extending in a proximal direction from its distal end and an intermediate portion reinforced with a tapered mandrel which provides optimal steerability and trackability characteristics. The distal end of the mandrel is coextensive with a proximal portion of the guide wire lumen. The intermediate portion of the catheter may have a marker for visual identification, and the tip of the catheter may include a radiopaque tip marker band for fluoroscopic identification. The short guide wire lumen catheter provides superior flexibility, a low profile, and low-friction engagement with the guide wire.
