The device description focuses on the physical characteristics and mechanical performance of a self-expanding stent and its delivery system. There is no mention of any software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is a stent used for palliation of malignant neoplasms in the biliary tree, which is a medical treatment aimed at alleviating symptoms and improving quality of life for patients.
No
This device is a stent, an implant designed to palliate malignant neoplasms by providing scaffolding in the biliary tree. It is a therapeutic device, not one that identifies or diagnoses a condition.
No
The device description clearly details a physical, implantable stent made of nitinol, along with a delivery system. It describes hardware components and their physical properties and performance testing related to these physical attributes.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "palliation of malignant neoplasms in the biliary tree." This describes a therapeutic intervention performed within the body, not a test performed on a sample taken from the body.
- Device Description: The description details a physical implant (a stent) designed to be placed in the biliary system. This is a medical device used for treatment, not for diagnostic testing.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing information for diagnosis, monitoring, or screening
The device is clearly a therapeutic medical device intended for implantation.

Device Description
The Zilver® 635 " Biliary Stent is a self-expanding, nitinol stent designed for excellent radial strength and optimal longitudinal flexibility. Constructed from a series of interconnected Z-shaped segments, the stent conforms to the shape of the biliary system and provides circumferential scaffolding throughout the stent's length. Gold radiopaque markers on each end of the Zilver® 635™ Biliary Stent, along with one radiopaque marker at the distal end of the delivery system, allow precise positioning of the stent. The stent's interconnected Z-shaped segments also keep foreshortening to a minimum.
The Zilver® 635" Biliary Stent comes preloaded in a 6 French delivery system. The stent is deployed with the use of a simple hand held device. The stent is available in unrestrained outer diameters of 4, 5, 6, 7, 8, 9 and 10 mm and in lengths of 20, 30, 40, 50, 60 and 80 mm. The 9, 10, 12, and 14 mm diameter stent with a cannula outside diameter of 1.6 mm is an addition to this product line.

§ 876.5010 Biliary catheter and accessories.
(a)
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.(b)
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.
