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.
