ABSTRACT:
A method of manufacture of a fiberscopic catheter having a tightly fitted optical glass fiber bundle received within an internal lumen of the catheter. The lumen for receiving the optical glass fiber bundle is heated and expanded under internal fluid pressure. The catheter and lumen are then cooled with the lumen still under the internal fluid pressure. After cooling, the fluid pressure is released and the lumen retains its expanded condition. An optical glass fiber bundle is inserted into the expanded lumen to a predetermined position within the catheter. The catheter and lumen are reheated to contract the expanded diameter of the lumen about the optical glass fiber bundle to provide a fiberscopic catheter having a tightly fitted fiber optic bundle within the catheter.
