The description focuses on the physical properties and mechanical performance of a self-expanding stent and its delivery system. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is a stent used to palliate malignant neoplasms in the biliary tree, which directly addresses a disease condition to alleviate symptoms.
No
Explanation: The device is a stent used for palliation of malignant neoplasms in the biliary tree, which is a therapeutic rather than a diagnostic function. It is designed to provide scaffolding and does not perform any diagnostic measurements or analyses.
No
The device description clearly details a physical, implantable stent made of nitinol, along with a delivery system. It also describes physical testing performed on the device. This is not a software-only medical device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
- Device Description: The Cook® Zilver™ Biliary Stent is a physical implantable device designed to be placed inside the biliary tree to palliate malignant neoplasms. It is a therapeutic device, not a diagnostic one.
- Intended Use: The intended use is to "palliation of malignant neoplasms in the biliary tree," which is a treatment or management purpose, not a diagnostic one.
- Lack of Diagnostic Elements: The description focuses on the physical properties of the stent (material, design, deployment) and its function within the body. There is no mention of analyzing samples, performing tests, or providing diagnostic information.
Therefore, based on the provided information, the Cook® Zilver™ Biliary Stent is a therapeutic medical device, not an In Vitro Diagnostic.

Device Description
The Cook® Zilver™ Biliary Stent is a self-expanding, nitonol stent designed for superior 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™ Biliary Stent, along with radiopaque markers on the delivery system, allow precise positioning of the stent. The stent's interconnected Z-shaped segments also keep foreshortening to a minimum.
The Zilver™ Biliary Stent comes preloaded in a 7.0 Fr. (OD) sheath delivery system. The stent is deployed with the use of a simple hand held device. The stent is being made available in unrestrained outer diameters of 12 and 14mm's and in the lengths of 25, 30, 40, 50, 60 and 80mm's

§ 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 Ms. Zwissler:
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, marl:et 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.

Päge 2 - Ms. Carol Zwissler
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807): labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification if the limitation statement described above is added to your labeling.
Please note that the above labeling limitations are required by Section 513(i)(1)(E) of the Act. Therefore, a new 510(k) is required before these limitations are modified in any way or removed from the device's labeling.
If you desire specific information about the application of other labeling requirements to your device (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4616. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
