摘要：
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.
