Abstract
Methods and apparatus for delivering a medical instrument over the exterior of an endoscope while the endoscope is installed in the patient's body allow the use of instruments which are too large to fit through the lumena of an endoscope. Furthermore, the invention allows the elimination of working lumena in an endoscope thereby minimizing the likelihood of contamination.

- a) a collar dimensioned to fit over the endoscope and having a radial opening such that said collar may be fit over the endoscope radially;
- b) a medical instrument coupled to said collar;
- and
- c) actuation means coupled to said medical instrument for remotely operating said medical instrument, wherein
- said medical instrument includes a pair of opposed jaws.
A method for delivering a medical instrument, the medical instrument including a pair of opposed jaws, over an endoscope to a procedural site while the endoscope is in a body lumen;
- said method comprising:
- a) attaching a medical instrument to a collar dimensioned to fit over the endoscope and having a radial opening such that said collar may be fit over the endoscope radially;
- b) attaching the collar to the endoscope by moving it radially over the endoscope;
- c) advancing the collar with the medical instrument along the surface of the endoscope to the procedural site;
