System facilitates transhepatic access to biliary tree; stent maintains luminal patency of biliary strictures resulting from malignant neoplasms. Delivery catheter compatible with 7F introducer systems; features multi-lumen design with priming lumen and .035" guidewire compatibility. Used by physicians in clinical settings to treat biliary obstructions. Stent deployment restores bile flow, potentially improving patient symptoms associated with malignant strictures. ## Clinical Evidence No clinical data. Evidence consists of functional and integrity bench testing, animal testing, and biocompatibility testing performed in accordance with ISO-10993 standards. ## Technological Characteristics Self-expanding nitinol stent; flexible delivery catheter; 7F introducer compatibility; multi-lumen design; .035" guidewire compatible. Biocompatibility evaluated per ISO-10993. ## Regulatory Identification A biliary catheter and accessories is a tubular flexible device used for temporary or prolonged drainage of the biliary tract, for splinting of the bile duct during healing, or for preventing stricture of the bile duct. This generic type of device may include a bile collecting bag that is attached to the biliary catheter by a connector and fastened to the patient with a strap. ## Special Controls *Classification.* Class II (special controls). The device, when it is a bile collecting bag or a surgical biliary catheter that does not include a balloon component, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9. ## Predicate Devices - Wallstent® Transhepatic Biliary Endoprosthesis with Unistep™ Delivery System ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
