The description focuses on the mechanical properties and deployment mechanism of a self-expanding stent, with no mention of AI or ML technologies.
Yes
The device is used for the palliation of malignant neoplasms and exerts force to dilate the biliary tree, which are therapeutic actions.
No
Explanation: The device, the Wilson-Cook Zilver Biliary Stent System, is indicated for the "palliation of malignant neoplasms in the biliary tree" by exerting force on them and causing dilation, which is a therapeutic intervention, not a diagnostic one.
No
The device description clearly describes a physical stent system with catheters and a self-expanding stent, which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "palliation of malignant neoplasms in the biliary tree." This describes a therapeutic intervention performed within the body to treat a condition.
- Device Description: The description details a physical device (a stent and delivery system) that is implanted to exert force and dilate a structure within the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens in vitro (outside the body), such as blood, urine, or tissue samples, to provide information for diagnosis, monitoring, or screening.
IVDs are used to perform tests on samples taken from the body, while this device is used to directly treat a condition within the body.

Device Description
The proposed Wilson-Cook Zilver Biliary Stent System-USW is a catheter within a catheter configuration. The pre-loaded (SEMS) Zilver Stent is held between the inner and outer catheter by natural expansion force at the distal tip. The inner catheter allows for wire guide access when placed through the accessory channel of an endoscope. The stent is self-expanding to nominal pressures to exert force on malignant neoplasms in the biliary tree resulting in dilation. It is offered in a variety of diameters/lengths to accommodate a range of biliary tumors.

§ 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.
