Embodiment Construction

[0026] definition

[0027] An ultra-thin endoscope, as the term is used herein, refers to an endoscope having an outer diameter of about 6.0 mm or less (including less than 5.0 mm). The term "sleeve" means the proximal structure of a balloon catheter comprising a connection structure (e.g., a Luer-type or other fluid-patent connection) configured to be operatively connected so that A fluid communication path between the source of inflation fluid, the catheter inflation lumen, and the balloon lumen is provided, and the sleeve includes a manifold-type sleeve, which may have more complex or ancillary structures. The terms "distal" and "proximal" should be understood in their standard usage to denote directions away from and towards the handle / user end of the tool or device, respectively (ie, away from and towards the patient, respectively).

[0028] refer to Figures 1A-1H , which describes a cholangioscopic procedure utilizing scope exchange assisted by a balloon catheter compr...

Abstract

A balloon catheter (400) may include a distal anchoring balloon (404) and a proximal hub (410) that is removable from the catheter body. The catheter body may include a valve structure (420) providing for maintaining the balloon in an inflated state during and after removal of the proximal hub. The valve preferably is constructed such that removal of the hub provides a low-profile proximal catheter end that will allow that proximal catheter end to pass through an endoscopic surgical device such as, for example, through an accessory channel of a standard duodenoscope and / or an ultra- slim endoscope / cholangioscope, facilitating a scope- exchange for use during, for example, a cholangioscopy or pancreatoscopy procedure. A method useful for scope exchange and / or introducing another elongate surgical device may utilize a balloon catheter with a distal anchoring balloon and a proximal hub that is removable from the catheter body.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application Nos. 61 / 256,773 and 61 / 256,755, filed October 30, 2009, and U.S. Provisional Application No. 61 / 329,243, filed April 29, 2010 , each of these provisional applications is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the claimed invention relate to a medical balloon catheter device configured to pass through an ultra-thin endoscope. More specifically, embodiments of the claimed invention relate to a balloon catheter including a proximally actuatable catheter lumen seal and a removable sleeve, and to methods of use thereof. Background technique [0004] Intraductal endoscopes are playing an increasingly important role in the diagnosis and non-surgical treatment of biliary and pancreatic diseases. Early attempts to examine the bile and pancreatic ducts endoscopically have been hampered by technical limitations of...
