Abstract
A stent is described that is capable of expanding and thereafter recoiling to its initial coiled state within a biliary duct. A delivery system is utilized to deploy the stent in its natural coiled state into a targeted site of an occluded biliary duct. A balloon from the delivery system is positioned within a lumen defined by the inner coiled arm of the stent. The inflation of a balloon from the delivery system causes the inner coiled arm to radially move outward and engage the outer coiled arm to form an expanded stent. The expanded stent can revert back to its recoiled state by deploying a balloon through a lumen of the expanded stent. Inflation of the balloon disengages the inner coiled arm from the outer coiled arm thereby collapsing the inner coiled arm radially outward and onto the outer coiled arm to form a recoiled stent. The recoiled stent can be removed from the biliary duct.
