| abstract |
A stent and a method for implanting a stent for prophylactically protecting a duct 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 cap portion operably connected to the proximal portion of the body, the cap portion is movable between a non-expanded configuration and an expanded configuration. The non-expanded configuration has a reduced diameter to facilitate advancement into the patient and the expanded configuration has an expanded diameter configured to protect an opening of the internal bodily duct so as to prevent an unintentional entry of an elongate medical device through the opening and into the passageway of the internal bodily duct. |
