1. An applicator for endoscopic delivery to treat biliary disease, comprising:
- an elongated member having a proximal end and a distal end adapted to be delivered transluminally from an exterior surface of a gallbladder to an interior lumen of the gallbladder without use of a common bile duct, the elongated member having a length adapted for delivery through a mammalian esophagus, stomach and duodenum, and an outer diameter smaller than a mammalian esophagus;
a lumen positioned within the elongated member with an aperture at the distal end of the elongated member, wherein the lumen within the elongated member extends a length of the elongated member and is sized to deliver at least one of a guiding element or a stirring element through the aperture at the distal end of the elongated member;
one or more material delivery apertures positioned at the distal end of the elongated member and sharing a coplanar relationship to another of the one or more material delivery apertures, wherein the one or more material delivery apertures configured to deliver a material to the interior lumen of the gallbladder or a gallbladder duct, wherein the one or more delivery apertures are configured to deliver the material in a 360 degree radial pattern, wherein the one or more material delivery apertures are in fluid communication with the lumen within the elongated member, and wherein the one or more material delivery apertures have a smaller diameter than the aperture of the lumen within the elongated member; and
a valve positioned within the lumen within the elongated member, wherein the valve is configured to control an amount and a timing of the delivery of the material to the interior lumen of the gallbladder.
