The description focuses on the mechanical properties and deployment mechanism of a physical stent, with no mention of software, algorithms, or data processing related to AI/ML.
Yes
The device is a stent used for palliation of malignant strictures in the biliary tree, which is a therapeutic intervention aimed at treating symptoms and improving quality of life.
No
Reason: The device description states that the Cook Zilver® 635" Biliary Stent is intended for "palliation of malignant neoplasms in the biliary tree" and "palliation of malignant strictures in the biliary tree." Palliation is a form of treatment, not diagnosis. The device is a stent used to open blocked bile ducts, which is a therapeutic function.
No
The device description clearly details a physical, self-expanding stent made of nitinol and a delivery system, indicating it is a hardware medical device. There is no mention of software as the primary or sole component.
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 is a therapeutic intervention performed within the patient's body.
- Device Description: The device is a self-expanding stent designed to be implanted in the biliary tree. This is a medical device used for treatment, not for testing samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing samples (like blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. The device's function is mechanical support and opening of a blocked passage.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

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 marker at the distal end of the delivery system, allow precise positioning of 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 100, 120, and 140 mm length stents are 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.

Dear Mr. Schilling:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act and the limitations described below. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
The Office of Device Evaluation has determined that there is a reasonable likelihood that this device will be used for an intended use not identified in the proposed labeling and that such use could cause harm. Therefore, in accordance with Section 513(i)(1)(E) of the Act, the following limitation must appear in the Warnings section of the device's labeling:
The safety and effectiveness of this device for use in the vascular system have not been established.
Furthermore, the indication for biliary use must be prominently displayed in all labeling, including pouch, box, and carton labels, instructions for use, and other promotional materials, in close proximity to the trade name, of a similar point size, and in bold print.
