ABSTRACT:
An instrument comprising an elongated control handle having a passage extending therethrough, an elongated flexible catheter body having at least one lumen and a distal end coupled to the control handle and an elongated flexible member extending through the passage and into the lumen and having a distal end portion. A tool is coupled to the distal end portion of the flexible member, and the tool is capable of performing a medical task within a patient. An elongated flexible image-transmitting member extends through the passage of the control handle and into the lumen. A position controller is mounted for sliding movement along the control handle and is drivingly coupled to the flexible members so that the axial positions of the tool and the image-transmitting member can be adjusted with respect to the distal end of the catheter body.
