Indications for Use
Advanix™ Biliary Stent with NaviFlex™ RX Delivery System 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 Biliary Stent with NaviFlex RX Delivery System; plastic biliary stent and delivery catheter. Stent provides drainage of biliary duct/gallbladder; maintains patency; prevents closure. Stent shapes include center bend and duodenal bend; tapered leading end for papilla access; rounded trailing end. Delivery system includes guide catheter and outer push catheter with locking mechanism; radiopaque markers for visualization. Used in clinical setting by physicians; delivered to biliary tract. Stent constructed of polyethylene; guide catheter of polyvinylidene fluoride; push catheter of polyether block amide. Device facilitates bile flow; aids healing; manages strictures/stones.
Clinical Evidence
Bench testing only. Evaluated per EN ISO 10993-1:2009 for biocompatibility (cytotoxicity, sensitization, reactivity, systemic toxicity, genotoxicity, implantation). Performance testing included drainage lumen ID, stent dimensions, repositionability, deployment/trackability force, compatibility (guidewire, duodenoscope, caps), and mechanical integrity (tensile strength, buckling resistance, marker band strength). All tests passed.
Technological Characteristics
Stent: Polyethylene. Guide catheter: Polyvinylidene fluoride. Push catheter: Polyether block amide. Radiopaque markers included. Diameters: 7Fr, 8.5Fr, 10Fr. Lengths: 5cm-18cm. Delivery system working length: 202.5cm. Mechanical delivery via RX (rapid exchange) catheter system with locking mechanism. Biocompatibility per EN ISO 10993-1:2009.
Indications for Use
Indicated for patients requiring biliary 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.

# 4. Proposed Device Description:
The proposed Advanix™ Biliary Stent with NaviFlex™ RX Delivery System consists of biliary plastic stents and delivery system catheters. They are sold separately or in a pre-loaded configuration, in which a stent comes attached to the catheter via a suture. The system is comprised of two (2) primary components: stent and delivery catheter with a locking mechanism. The Advanix Biliary Stent allows for drainage of the biliary duct and gall bladder by preventing closure and maintaining the patency of the biliary duct. These biliary stents are provided in center bend and duodenal bend shapes and have leading and trailing bars, a tapered leading end tip to facilitate access through the papilla, and a rounded tailing end to match the profile of the push catheter portion of the delivery system.
The Advanix Biliary Stent will be offered in 7Fr. 8.5Fr, and 10Fr diameters. The stent leneths for each diameter vary from 5cm-18cm stent lengths. The Advanix biliary stents are constructed of a Polyethylene material.
The NaviFlex RX Delivery System will be offered in 202.5cm working length. The delivery system consists of a guide catheter and outer push catheter. The guide catheter is constructed of Polyvinylidene fluoride material. The guide catheter also includes a radiopaque marker. The push catheter is composed of polyether block amide material and also has a Nylon repositioning suture.

# 5. Intended Use:
Advanix™ Biliary Stent with NaviFlex™ RX Delivery System 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.
# 6. Technological Characteristics:
The proposed Advanix™ Biliary Stent with NaviFlex™ RX Delivery System has the same technological characteristics as the predicate Microvasive® Biliary Stent and Delivery System (K965147).
The proposed device has the same intended use and is placed using the same methodology as the predicate device. Both the proposed and predicate device function in the same manner allowing for biliary drainage through the lumen.
The shape of the proposed Advanix Biliary Stent is the same as the predicate Microvasive Biliary Stent and Delivery System and also includes an additional center bend stent shape.
The materials of the proposed Advanix Biliary Stent have been modified to the polymer materials mentioned above in part 4 of this 510(k) Summary.
## 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™ 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 NaviFlex™ RX Delivery System was evaluated in accordance with EN ISO 10993-1:2009. The following tests were performed on the delivery system: Cytotoxicity, Sensitization, Intracutaneous Reactivity, and USP Physicochemical.
The following tests were conducted on the Advanix™ Biliary Stent with NaviFlex™ RX Delivery System: Drainage Lumen ID, Stent Length, Stent OD, Stent Shape, Repositionability, Deployment Force, Trackability Force, Guidewire Compatibility, Duodenoscope Compatibility, Barb Flap Cover Compatibility, Biopsy Cap Compatibility, Delivery System Working Length, Delivery System OD, Guide Catheter Pushability, RX Port Buckling Resistance, Locking Mechanism Retention Ability, Locking Mechanism to Dual Lumen Catheter Tensile Strength, Dual Lumen Catheter to Single Lumen Catheter Tensile Strength, Pullwire Assembly to Guide Catheter Tensile Strength, Pullwire Tensile Strength, Guide Catheter RO Marker Band Strength, and Push Catheter RO Marker Band Strength.
#### 8. Conclusion:
All biocompatibility tests conducted on the Advanix™ Biliary Stent with NaviFlex™ RX Delivery System passed. Therefore, the Advanix Biliary Stent with NaviFlex RX Delivery System is considered biocompatible for its intended use.
All device bench test results were acceptable. The data demonstrate that the Advanix™ Biliary Stent with NaviFlex™ RX Delivery System sufficiently meets the design specifications and is suitable for the intended use.
Boston Scientific Corporation has demonstrated that the proposed Advanix™ Biliary Stent with NaviFlex™ RX Delivery System is substantially equivalent to Boston Scientific Corporation's currently marketed Microvasive® Biliary Stent and Delivery System (K965147).
