Abstract
Abstract A catheter device insertable into a body lumen and incorporating combined ultrasound ablation and endoscopic visualization apparatus. The catheter device generally comprises an elongate catheter body including an ultrasound transmission member extending longitudinally therethrough having a proximal end connectable to an ultrasound transducer such that ultrasonic energy will pass through the ultrasound transmission member to the distal end thereof. Also extending longitudinally through the catheter body is a light transmission member having a proximal end connectable to a light source such that light will pass through the light transmission member to the distal end thereof, and an optical image transmission member having a proximal end connectable to an external image viewing apparatus such that an optical image will pass through the optical image transmission member from the distal end thereof to the external image viewing apparatus.
