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.

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. 2. The device of claim 1 wherein the device is formed from a bioresorbable material. 3. The device of claim 1 wherein the device is removable. 4. The device of claim 1 wherein the device is expandable. 5. The device of claim 1 wherein a cross-sectional area of the device is variable along a length. 6. The device of claim 1 wherein the device is configured for deployment by at least one of an endoscope, a needle, a guidewire, a guidance catheter, and a dilatation catheter. 7. The device of claim 1 further comprising a flareable end. 8. The device of claim 1 wherein the component has one or more clips configured to secure the component at one or more positions. 9. The device of claim 1 further comprising one or more fenestrations. 10. The device of claim 1 wherein the device is configured from one or more wires. 11. The device of claim 1 wherein at least one of the distal retaining feature and the proximal retaining feature extend from the tubular portion and curve back toward the tubular portion. 12. A biliary disease treatment device 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, configured to be delivered by an endoscope to a gastrointestinal site in proximity to a gallbladder, 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. 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; andpositioning the component between the access lumen in the body and the gallbladder to create a lumen therebetween. 14. The method of claim 13 further comprising the step of passively retaining a distal end of the guidewire in the gallbladder while the guidewire is used to deliver additional elements. 15. The method of claim 13 further comprising delivering a substance to the gallbladder via the created lumen. 16. 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 extending radially beyond an outer surface of the tubular portion, and a distal retaining feature extending radially beyond 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. 17. The device of claim 1, wherein the plurality of radially extending elements are divided into separate segments. 18. The device of claim 1, wherein the retaining features comprise at least one of silicone, urethane, Nitinol, and stainless steel.
