摘要: Multi-lumen catheters with first and second expandable members are configured so that one expandable member dilates the Sphincter of Oddi and the second anchors within the biliary duct distal to the Common Bile Duct/Cystic Duct junction or within the cystic duct. The multi-lumen catheters include a primary lumen sized and configured for delivering a flushing agent to remove gallstones together or separately with a dye to complete a Cholangiogram and also include at least one lumen in fluid communication with the first and second expandable members.

摘要: A stent, shunt, or plug, for at least partial insertion into a patient, can include a deformable elongated tubular body including a proximal portion and a distal portion and defining a longitudinal lumen of the tubular body therebetween. The deformable elongated body can be capable of an expanded state and a collapsed state. The tubular body can include a sheath and a plurality of magnetizable or magnetic elements for providing magnetic repulsion, after being magnetically actuated, to maintain the tubular body to maintain the expanded state.

摘要: An anchored dilator includes a push tube having proximal and distal push tube portions. A dilator tip is coupled with the distal push tube portion and is configured for selectable coupling with a catheter. The dilator tip includes an anchor cuff having a cuff interface. The anchor cuff is configured to transition between a shuttle configuration having a shuttle profile and an anchored configuration having an anchored profile larger than the shuttle profile. A cuff operator assembly is configured to transition the anchor cuff between the anchored and shuttle configurations. The cuff operator assembly includes a cuff operator movably coupled with the dilator tip, and an operator shaft coupled with the cuff operator. The operator shaft extends toward the proximal push tube portion. Actuation of the cuff operator with the operator shaft transitions the anchor cuff between the shuttle configuration and the anchored configuration.

摘要: A temporary aortic occlusion device is disclosed, having an expandable locator portion and an expandable occlusion portion. The expandable locator portion assists a user in determining whether the distal end of the device has been advanced within a patient's aorta, and the occlusion portion is expanded to occlude the patient's aorta, preferably below the renal arteries.
