Abstract:
1. A rearward viewing endoscopic imaging catheter, comprising: a longitudinally extending tubular member having a proximal end, a distal end, an outer surface, and a longitudinal axis; an optical element positioned within the tubular member distal end; an imaging sensor positioned within the tubular member distal end and in communication with the optical element, an illumination source that is located proximal to the imaging sensor and illuminates around the outer surface of the tubular member with a direction of illumination substantially perpendicular to the longitudinal axis, wherein the optical element and the imaging sensor are configured to capture an image comprising a rearward-looking conical field of view centered at the longitudinal axis of the tubular member of an organ or a corporeal wall encircling the intrabody lumen.
