Abstract
A surgical cutting instrument comprising an elongated flexible hollow-body tube having a lumen extending therethrough, and having a proximal end and distal end. A cutting, grasping or manipulating mechanism is coupled to the distal end of the body portion. Control wire means having proximal and distal ends, extend through the lumen in the body portion, and are coupled to the cutting grasping or manipulating mechanism. The control wire means contains on its surface a polymeric film resin to reduce friction between the control wire and inner surface of the flexible hollow body tube, and/or to seal the control wire within the flexible hollow body tube.
