1. A device for treating biliary disease comprising:
- a component configured for establishing fluid communication between a gallbladder and a target location within a gastrointestinal tract of a mammal, the component having a proximal end and a distal end with a lumen extending therethrough, a tubular portion with a proximal retaining feature on an outer surface of the tubular portion and a distal retaining feature on the outer surface of the tubular portion, wherein the proximal retaining feature has a disc shape and the distal retaining feature has a plurality of radially extending elements projecting outward therefrom, wherein the disc shape has a curved edge such that the device is atraumatic to adjacent tissue, wherein the tubular portion and the retaining features comprise dissimilar materials, and wherein the tubular portion comprises soft durometer molded silicone material with durometer in a range of 20-90 A.

Abstract
The application discloses devices, delivery tools, systems, and methods for treating biliary disease. Device comprise, for example, a component configured for deployment between a gallbladder and location within a gastrointestinal tract of a patient which has a proximal end and a distal end with a lumen extending therethrough. A method of deploying the device can be achieved by, for example, creating a duct or fistula between a gallbladder lumen and a portion of a gastrointestinal tract; and providing for drainage from the gallbladder to the gastrointestinal tract.

13. A method of delivering a device to treat biliary disease comprising:
-
using an endoscope to place at least one of a guidewire, a needle, a guidance catheter, and a dilatation catheter between an access lumen in a body and a gallbladder; inserting a delivery catheter over the at least one of guidewire, needle, guidance catheter, and dilatation catheter and into the gallbladder; delivering a component configured for establishing fluid communication between a gallbladder and a target location within a gastrointestinal tract of a mammal, the component having a proximal end and a distal end with a lumen extending therethrough, a tubular portion with a proximal retaining feature on an outer surface of the tubular portion and a distal retaining feature on the outer surface of the tubular portion, wherein the proximal retaining feature has a disc shape and the distal retaining feature has a plurality of radially extending elements projecting outward therefrom, wherein the disc shape has a curved edge such that the component is atraumatic to adjacent tissue, wherein the tubular portion and the retaining features comprise dissimilar materials, and wherein the tubular portion comprises soft durometer molded silicone material with durometer in a range of 20-90 A; and positioning the component between the access lumen in the body and the gallbladder to create a lumen therebetween. - View Dependent Claims (14, 15)
