The device description and performance studies focus on the mechanical properties and deployment of a physical stent, with no mention of AI or ML technologies.
Yes
The device is indicated for "palliation of malignant neoplasms in the biliary tree," which is a therapeutic purpose.
No
Explanation: The device is described as a stent used for the palliation of malignant neoplasms, indicating a therapeutic function rather than a diagnostic one.
No
The device description clearly details a physical, implantable stent made of nitinol, a delivery system, and a hand-held deployment device. These are hardware components, not software.
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 samples taken from the body.
- Device Description: The description details a self-expanding stent designed to be implanted in the biliary tree. This is a medical device used for treatment, not for diagnostic testing of biological samples.
- Lack of IVD Characteristics: The description does not mention any components or functions related to analyzing biological samples (like blood, urine, tissue, etc.) or providing diagnostic information based on such analysis.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a therapeutic implant.

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 seqments, 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" Biljary Stent comes prefoaded 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 and 60 mm.

§ 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.
