Patent number: 8845663Abstract: A stent and a method for implanting a stent for decompression and anastomosis formation are provided. The stent includes a non-expandable, generally tubular body having a proximal portion and a distal portion, a lumen extending through at least a portion of the body, a distal opening in the distal portion in fluid communication with the lumen and a proximal opening in the proximal portion in fluid communication with the lumen. The stent further includes a first magnetic element positioned on the distal portion of the tubular body and a second magnetic element movably positionable on the proximal portion of the tubular body. The second magnetic element is configured to surround and move over the proximal portion of the tubular body towards the first magnetic element.Type: GrantFiled: December 19, 2012Date of Patent: September 30, 2014Assignee: Cook Medical Technologies LLCInventor: Kevin Chmura

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: 20090048654Abstract: A stent delivery system and a method for delivering a stent are provided. The stent delivery system includes an outer sheath having a proximal portion, a distal portion and a first lumen extending at least partially through the sheath. The system further includes an inner shaft slidably received within the first lumen and extending at least partially through the sheath. A tubular non-expandable stent is slidably positionable within the first lumen, disposed distal to the inner shaft and operably contacts a pushing surface on the inner shaft. The inner shaft and the stent are slidable relative to the outer sheath, the outer sheath providing sufficient rigidity to the stent for delivery of the stent to a delivery site.Type: ApplicationFiled: August 13, 2008Publication date: February 19, 2009Applicant: Wilson-Cook Medical Inc.Inventors: Kevin Chmura, John M.
