What is it indicated for?

The ConvertX Biliary Stent System with releasable drainage catheter is delivered percutaneously and is intended for internal drainage of the bile ducts, for splinting of the bile ducts during healing, or for providing bile duct patency in a stricture or past a stone while maintaining external access to the stent, as well as providing external drainage. For patients for whom external drainage is not, or no longer desirable, the releasable drainage catheter may be removed, leaving the stent to provide internal drainage from the bile duct to the duodenum.

Indications for use as stated in the FDA summary.
