Abstract
An adjustable needle mechanism for gastrointestinal use in combination with an endoscope. The needle is received within a catheter or sheath and is movable between a first position in which it projects out of the catheter and a second position in which it is withdrawn into the catheter. A rotatable knob is provided to adjust the extent of projection of the needle when it is in the first position thereby eliminating any necessity to trim the end of the catheter.
