Abstract:
1. A steerable imaging catheter comprising: an elongated catheter tube having a proximal end, a distal end, and diametrically-opposed lumens extending therethrough, each lumen opening at the distal end; at least one steering cable extending along the catheter tube between the proximal and distal ends of the catheter tube to control the movement of the distal end of the catheter tube; and a fiber optic cable having a proximal end and a distal end, the fiber optic cable extending along the catheter tube between the proximal and distal ends of the catheter tube, and the fiber optic cable transmitting illumination light from its proximal end to its distal end while transmitting an image from its distal end to its proximal end, wherein the fiber optic cable includes: wherein the fiber optic cable is disposed in one of the diametrically-opposed lumens, the one of the diametrically-opposed lumens being offset from a central longitudinal axis of the catheter tube.
