Biliary Shunts, Delivery Systems, Methods of Using the Same and Kits Therefor

Abstract

The application discloses devices, systems, kits 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.

Benefits of technology

[0025]Devices according to any one of the configurations disclosed can be formed from a bioresorbable material. Moreover, the devices can be removable and/or expandable. The devices can also be configurable in one or more configurations selected from a deployment configuration, a delivery configuration and a final configuration. Moreover, the devices can be configured such that a profile of the device changes between said configurations. Additionally, or in the alternative, a cross-sectional area of the device can be variable along a length of the devices. In some configurations a component or implant can be configured such that it has a flareable end, suitable flareable ends include ends that are generally hemispherical. Additionally, components or implants can comprise a configurable retainable feature. In some aspects, components or implants can comprise one or more clips configured to secure the components or implants at one or more positions. In some configurations, one or more fenestrations may be provided. Moreover, the lumen or conduit can be configurable to provide restrictable fluid flow or to provide for a valve, such as a flow-restrictor or one-way valve. Any of the configurations of the device can be constructed such that the device is flexible. The system or device can also be configured to include a generally elongate tube that is adapted and configured to extend into the gastrointestinal tract. Configurations that include an elongate tube can be configured such that the tube is patent at a first end; the patent first end can be for placement adjacent the gallbladder. In still other configurations, the elongate tube is not patent at a second end. Moreover, the tube can be configured such that it has an adjustable length. Additionally, one or more fluid control components can be provided to the designs. Additionally, an enlargeable portion comprising two or more legs can be provided.

[0026]Another aspect of the invention is directed to a kit for treating biliary disease comprising a duct forming component positioned between a gallbladder and a gastrointestinal tract. The kit can comprise any of the devices or systems described herein. Additionally, compounds can be provided for delivery to a tissue. Compounds or materials include, but are not limited to, for example, one or more of each of sclerosing agents, antibiotics, inflammatory agents, anti-inflammatory agents, biocompatible gels, and biocompatible foams. Additionally, a catheter, guidewire, needle, guidance catheter or balloon catheter can be provided. In some aspects, the kit can also include an ablation device. Additional components of the kits include, for example, one or more of each of a pair of scissors, a scalpel, a swab, a syringe, a hemostat, a lubricant, a needle, a snare, an antiseptic, and an anesthetic.

[0027]Yet another aspect of the invention is directed to a method for treating biliary disease. A method of treating biliary disease comprises: (a) creating a duct or fistula between a gallbladder lumen and a portion of a gastrointestinal tract; and (b) providing for drainage from the gallbladder to the gastrointestinal tract. Additionally, the method can comprise the step of delivering a substance to the gallbladder via the duct. Additional method steps include delivering a device to the gallbladder through the duct. Suitable devices to be delivered include one or more of a stent, a drug-coated stent, a catheter, a needle, a guidance catheter, a balloon dilatation catheter and/or a guidewire. In some cases, the step of creating the duct further comprises the step of inserting a device in communication between the gastrointestinal tract and the gallbladder lumen. The step of creating the duct between a gallbladder lumen and a portion of a gastrointestinal tract can further comprise the step of inserting a conduit between the gallbladder lumen and the portion of the biliary system. In so

Problems solved by technology

Deployment of these devices can, in some instances, cause a conduit to be formed between a gallbladder lumen and a target location within the gastrointestinal tract.
