Embodiment Construction

[0048] FIG. 1 is a schematic partial cross-sectional view of a sleeve assembly 20 for an endoscope 22 according to an embodiment of the present invention. The assembly 20 includes a dispenser 24 and a flexible sleeve 26. Typically, the dispenser 24 is composed of a rigid plastic material, such as PVC, while the sleeve 26 is composed of a flexible, biocompatible plastic, such as polyamide, with a thickness of approximately 20 μm. In an exemplary embodiment, the endoscope 22 is a colonoscope having an outer diameter of about 13 mm, while the sleeve 26 has a diameter of about 20 mm.

[0049] The endoscope 22 has a distal end 30, which typically includes illumination and viewing optics (not shown), and optionally includes one or more working channel distal openings (e.g., as shown in FIG. 7) . When the endoscope is inserted into the sleeve 26, the distal end of the endoscope is engaged with the distal end 28 of the sleeve including a transparent window through which the observation op...

Abstract

Apparatus ( 20 ) for sheathing an endoscope ( 22 ) includes a dispenser ( 24 ), having entry and exit ports ( 36, 39 ) defining a transit passage through which the endoscope may pass, and a flexible sleeve ( 26 ), at least a portion of which is bunched in a vicinity of the dispenser. The sleeve includes a distal end ( 28 ), which is closed, and a proximal end, which is open and fixed to the dispenser so that as the endoscope is advanced in a distal direction through the transit passage, the endoscope enters into the sleeve through the proximal end and engages the distal end of the sleeve, thus causing the bunched portion of the sleeve to be extended so as to cover a distal part of the endoscope that protrudes through the exit port.

Description

[0001] Cross-references to related applications [0002] This application claims the priority of U.S. Provisional Patent Application 60 / 404,110 filed on August 15, 2002, which is incorporated herein by reference. Technical field [0003] The present invention relates generally to endoscopy, and more particularly to covering the endoscope with a disposable sleeve during insertion of the endoscope into a body passage. Background technique [0004] The use of a disposable sleeve (also called a sheath) to cover an endoscope is well known in the art. It is well known that flexible endoscopes such as colonoscopes are difficult to completely clean and disinfect after use, which leads to the problem of cross-infection between patients. These problems can be avoided by covering the endoscope with disposable sleeves that are thrown away after use. [0005] For example, US Patent 4,646,722, the disclosure of which is incorporated herein by reference, describes a protective endoscope sheath a...
