The 510(k) summary describes a mechanical device (a stent) and its delivery system. There is no mention of AI, ML, image processing, or any software-driven analytical capabilities. The performance studies focus on the physical properties and performance of the stent itself.
Yes
The device is a stent used for palliation of malignant neoplasms in the biliary tree, which is a therapeutic intervention.
No
Justification: The device is a biliary stent used for palliation of malignant neoplasms, which is a therapeutic rather than a diagnostic function.
No
The device description clearly states it is a balloon-expandable, stainless steel stent, which is a physical hardware device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The Cook® Formula™ 418™ Biliary Stent is a physical implantable device (a stent) used to palliate malignant neoplasms in the biliary tree. It is directly inserted into the body to provide structural support and maintain patency.
- Lack of Specimen Analysis: The description and intended use do not involve the analysis of any specimens taken from the body.
Therefore, based on the provided information, the Cook® Formula™ 418™ Biliary Stent is a therapeutic medical device, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The Cook® Formula™ 418™ Biliary Stent is indicated for use in palliation of malignant neoplasms in the biliary tree.

§ 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.

The general controls provisions of the provisions of the rice and 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 The Office of Doriet 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, i untilermore, the marcarton labels, instructions for use, and other promotional materials, in close proximity to the trade name, of a similar point size, and in bold print.

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.
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.
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.
