Intended Use

Advanix™ Double Pigtail Biliary Stent is intended for delivery of the stent to the biliary tract for drainage of the bile ducts, for splinting of a bile duct during healing, or for providing bile duct patency in a stricture or past a stone.

Device Story

Advanix™ Double Pigtail Biliary Stent is a plastic biliary stent designed for drainage, splinting, or maintaining patency of bile ducts. Device features proximal and distal pigtails, lateral drainage holes, and a tapered tip. Available in 7Fr and 10Fr diameters with lengths ranging from 3cm to 15cm. Constructed from Styrene Butadiene Styrene. Used by physicians in clinical settings to facilitate biliary drainage through the lumen. Stent is placed using standard biliary catheterization techniques. Benefits include improved bile flow and ductal support in patients with strictures or stones.

Clinical Evidence

No clinical data. Evidence consists of bench testing including biocompatibility (cytotoxicity, sensitization, reactivity, systemic toxicity, genotoxicity, implantation) and mechanical performance testing (drainage lumen ID, stent length, OD, shape, deployment force, trackability, and compatibility). All tests met specifications.

Technological Characteristics

Styrene Butadiene Styrene plastic biliary stent. Features proximal/distal pigtails, lateral drainage holes, tapered tip. Diameters: 7Fr, 10Fr. Lengths: 3cm-15cm. Biocompatibility per EN ISO 10993-1:2009. Non-electronic, mechanical device.

Indications for Use

Indicated for patients requiring biliary tract drainage, bile duct splinting during healing, or maintenance of bile duct patency in the presence of strictures or stones.

Regulatory Classification

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

• Microvasive® Biliary Stent and Delivery System (K965147)
• Microvasive® Drainage Stent (K834468)

## 5. Intended Use:

Advanix™ Double Pigtail Biliary Stent is intended for drainage of the bile ducts, for splinting of a bile duct during healing, or for providing bile duct patency in a stricture or past a stone.

## 6. Technological Characteristics:

The proposed Advanix™ Double Pigtail Biliary Stent has the same technological characteristics as the predicate Microvasive® Drainage Stent (K834468) and Microvasive® Biliary Stent and Delivery System (K965147).

The proposed device has the same intended use as the predicate Microvasive Biliary Stent and is placed using the same methodology as both of the predicate devices. Both the proposed and predicate devices function in the same manner allowing for biliary drainage through the lumen.

The pigtail shape and material for the Advanix Double Pigtail Biliary Stent are the same as the predicate Microvasive Drainage Stent.

#### 7. Performance Data:

In-vitro testing has been performed and all components, subassemblies, and/or full devices met the required specifications for the completed tests.

The proposed Advanix™ Double Pigtail Biliary Stent was evaluated in accordance with EN ISO 10993-1:2009. The following tests were performed on the stent: Cytotoxicity, Sensitization, Intracutaneous Reactivity, Systemic Toxicity -Acute Systemic Toxicity, Subacute Toxicity -Intravenous and Intraperitoneal, Genotoxicity - Ames Assay and Mouse Lymphoma, Implantation, and USP Physicochemical.

The following tests were conducted on the Advanix™ Double Pigtail Biliary Stent: Drainage Lumen ID, Stent Length, Stent OD, Stent Shape, Deployment Force, Trackability Force, Duodenoscope Compatibility, and Barb Flap Cover Compatibility.

#### 8. Conclusion:

All biocompatibility tests conducted on the Advanix™ Double Pigtail Biliary Stent passed. Therefore, the Advanix Double Pigtail Billiary Stent is considered biocompatible for its intended use.

All device bench test results were acceptable. The data demonstrate that the Advanix Double Pigtail Biliary Stent sufficiently meets the design specifications and is suitable for the intended use.

Boston Scientific Corporation has demonstrated that the proposed Advanix™ Double Pigtail Biliary Stent is substantially equivalent to Boston Scientific Corporation's currently marketed Microvasive® Drainage Stent (K834468) and Microvasive® Biliary Stent and Delivery System (K965147).
