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.

Claims

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 section with a radially extending proximal flange and a radially extending distal flange wherein at least one of the proximal flange and distal flange is disc shaped and at least one of the proximal flange and the distal flange has a plurality of radially extending elements.

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.

7. The device of claim 1 wherein a cross-sectional area of the device is variable along a length.

8. 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.

9. The device of claim 1 further comprising a flareable end.

10. The device of claim 1 wherein the component has one or more clips configured to secure the component at one or more positions.

11. The device of claim 1 further comprising one or more fenestrations.

15. The device of claim 1 wherein the device is configured from one or more wires.

19. The device of claim 1 wherein at least one of the distal flange and proximal flange extend from the tubular section and curve back toward the tubular section.

35. A method of delivering a device to treat biliary disease comprising:

a. 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;

b. inserting a delivery catheter over the at least one of guidewire, needle, guidance catheter, and dilatation catheter and into the gallbladder;

c. 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 section with a radially extending proximal flange and a radially extending distal flange wherein at least one of the proximal flange and distal flange is disc shaped and at least one of the proximal flange and the distal flange has a plurality of radially extending elements; and

d. positioning the component between the access lumen in the body and the gallbladder to create a lumen therebetween.

36. The method of claim 35 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.

39. The method of claim 35 further comprising the step of delivering a substance to the gallbladder via the created lumen.
