Stent delivery system with imaging capability
First Claim
1. A stent delivery system, comprising:
- a catheter shaft defining first and second lumens therein;
a guidewire removably received within one of the first or second lumens;
a fiber optic cable having a first end and a second end, the fiber optic cable transmitting illumination light from its first end to its second end while transmitting an image from its second end to its first end, the fiber optic cable being received within another of the first or second lumens; and
a stent positioned over the catheter shaft.

Abstract
A stent delivery system includes a catheter shaft defining two lumens, for respectively receiving a guidewire and a fiber optic cable having a viewing capability. Specifically, the fiber optic cable has a first (e.g., proximal) end and a second (e.g., distal) end, and is adapted for transmitting illumination light from its first end to its second end while transmitting an image from its second end to its first end. The system further includes a stent positioned over the catheter shaft, and may also include means for deploying the stent. The stent may be of a self-expanding type or of an inflation type. The fiber optic cable is used to visually inspect proper deployment of the stent before, during, and after the stent deployment.
