Method of using a catheter-sleeve assembly for an endoscope
First Claim
1. The endoscopic treatment method comprising the steps of:
- inserting an endoscope with a substantially uniform outer surface into a body opening for viewing,wrapping a catheter sleeve carrying at least one lumen for insertion of instruments into the endoscope viewing field about the endoscope outer surface at a position outside the body while the endoscope remains in a viewing position in the body thereby to attain a sliding relationship for moving the catheter sleeve along the endoscope surface to a distal end work site while the endoscope remains in a viewing position in the body, andmoving the catheter sleeve into the body along the endoscope outer surface to a said distal end work site.

Abstract
A catheter sleeve assembly with a zipper-like locking structure is positioned on the outer cylindrical surface of an endoscope at a position outside the body while the endoscope is in viewing position inside the body. The zipper-like locking structure is split and the catheter-sleeve assembly is positioned about the endoscope body and locked into place. The catheter-sleeve assembly is then shuttled into and out of the distal viewing site along the body of the endoscope by manual manipulation while the endoscope remains in viewing position. Surgical stapling and tissue removal procedures can be performed with endoscopic surgical instruments passed down a lumen provided in the catheter-sleeve assembly.
