Publication number: 20110118546Abstract: A balloon catheter may include a distal anchoring balloon and a proximal hub that is removable from the catheter body. The catheter body may include a valve structure 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.Type: ApplicationFiled: October 21, 2010Publication date: May 19, 2011Applicant: Cook Endoscopy/Wilson CookInventors: Travis E.

Publication number: 20100160931Abstract: The present embodiments provide a tacking device for engaging tissue, which may be useful for coupling a graft member to tissue or facilitating closure of a bodily opening. In one embodiment, the tacking device comprises a main body having proximal and distal ends, a proximal base member disposed at the proximal end of the main body, and at least one tissue engaging member disposed at the distal end of the main body. A spring member is disposed to surround the main body and extends from the proximal base member. In use, the spring member has a relaxed state in which it is biased to extend distally towards the at least one tissue engaging member, and further has a compressed state in which the distal end of the spring member is spaced further apart from the at least one tissue engaging member. Therefore, one or more tissue segments of varying thickness are adapted to be captured between the distal end of the spring member and the at least one tissue engaging member.Type: ApplicationFiled: December 15, 2009Publication date: June 24, 2010Applicant: Wilson-Cook Medical Inc.Inventors: John A Karpiel, Tyler E.
