The 510(k) summary describes a mechanical device (stent and catheter) and its accessories. There is no mention of software, algorithms, data processing, or any terms related to AI/ML. The performance studies focus on material properties, mechanical function, and biological compatibility.
Yes
The device is intended for internal drainage, splinting, or providing patency in bile ducts, which are direct actions to treat a medical condition.
No.
The ConvertX Biliary Stent System is described as an interventional device intended for internal drainage and maintaining patency of bile ducts, not for diagnosing a condition.
No
The device description clearly outlines physical components such as a stent, catheter, hub, and accessories like cannulas. The performance studies also focus on physical properties and biological compatibility, not software validation.
Based on the provided text, the ConvertX Biliary Stent System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly describes a device that is delivered percutaneously (inserted into the body) for internal drainage, splinting, and maintaining patency of the bile ducts. This is an in vivo (within the living body) application.
- Device Description: The description details a physical device (stent and catheter) that is inserted into the body. It talks about drainage holes, pigtails forming in the bile duct and duodenum, and external access. These are all related to the device's function within the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) in vitro (outside the body) to provide information for diagnostic purposes.
IVD devices are used to perform tests on samples taken from the body, while the ConvertX Biliary Stent System is a therapeutic device used to treat a condition within the body.
N/A
Intended Use / Indications for Use
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.

Device Description
The ConvertX Biliary Stent System is a sterile, single-use non-vascular interventional device inserted using percutaneous access techniques to re-establish internal drainage 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. The ConvertX Biliary System allows for external drainage and access as needed.
The ConvertX Biliary Stent System has two primary components: a double pigtail Biliary Stent and a Releasable Drainage Catheter with Hub.
The ConvertX Biliary Stent System is a single lumen device that has a detachable Biliary Stent with proximal and distal loops (pigtails). Both proximal and distal loops (pigtails) contain drainage holes. The proximal pigtail forms in the bile duct, while the distal pigtail forms in the duodenum. The distal pigtail has a tapered, atraumatic tip. Drainage can occur internally (from the bile duct to the duodenum) or externally (from the bile duct to the outside of the patient). A suture ("Loop Suture") is threaded through the proximal pigtail enabling the pigtail, straightened for delivery, to be closed in the bile duct.
The ConvertX Biliary Stent System's Hub has three ports which are used for both ends of the Loop Suture, external drainage of bile and the release wire. Ends of the Loop Suture and the Release Wire are connected to separate pull tabs within the Hub. The Releasable Drainage Catheter and Loop Suture may be detached from the Biliary Stent when external drainage is no longer necessary, leaving the stent in place. While still attached, the Releasable Drainage Catheter may be used to withdraw the Biliary Stent. The ConvertX Biliary Stent System is radiopaque throughout its length and has a marker on the stent between junction and proximal loop
The ConvertX Biliary Stent System is comprised of the following functional components:
- Biliary Stent
- Releasable Drainage Catheter with Hub
The ConvertX Biliary Stent System is supplied with the following accessories:
- Metal Stiffening Cannula
- Luer Cap
- Plastic Stiffening Cannula
- Loop Straightener

Summary of Performance Studies
Design verification / performance testing for the ConvertX Biliary Stent System was completed in accordance with applicable sections of ASTM F1828-97 - Standard Specification for Ureteral Stents (using simulated bile), ASTM F2129-17- "Standard Test Method for Conducting Cyclic Potentiodynamic Polarization Measurements to Determine the Corrosion Susceptibility of Small Implant Devices": X2.5 Simulated Bile (Human Simulated Bile). ASTM F623-99 - Standard Performance Specification for Foley Catheters, ISO 10555-1: 2013 -Intravascular catheters - Sterile and single-use catheters, Part 1: General requirements, and the FDA Guidance for the Content of Premarket Notifications for Ureteral Stents. Biological testing was performed in accordance with applicable sections of ISO 10993 – Biological Evaluation of Medical Devices. MRI Compatibility was evaluated according to ASTM F2182-11a - Standard Test Method for Measurement of Radio Frequency Heating On or Near Passive Implants During Magnetic Resonance Imaging, ASTM F2119-07 - Standard Test Method for Evaluation of MR Image Artifacts from Passive Implants, ASTM F2052-15 - Standard Test Method for Measurement of Magnetically Induced Displacement Force on Medical Devices in the Magnetic Resonance Environment, and ASTM F2503-13 - Standard Practice for Marking Medical Devices and Other Items for Safety in Magnetic Resonance Environment. Radiopacity of the predicate ConvertX Nephroureteral Stent System was evaluated in accordance with ASTM F640-12 - Standard Test Methods for Determining Radiopacity for Medical Use.
Key results: The ConvertX Biliary Stent System, including its packaging, met the predetermined acceptance criteria. No new safety or performance issues were raised during testing.

Conclusion
The ConvertX™ Biliary Stent System has the same intended use and similar technological characteristics as the Advanix Double Pigtail Stent System and Expel Drainage Catheter marketed by Boston Scientific. Moreover, performance testing contained in this submission demonstrate that any differences in their technological characteristics do not raise any new questions of safety or effectiveness. Thus, the ConvertX Biliary Stent System is substantially equivalent to the predicate devices.
