The device description focuses on the mechanical components of a stent and delivery system, with no mention of AI or ML. The performance studies are also focused on mechanical and material properties.
Yes
The device is a stent system designed to maintain patency of biliary strictures produced by malignant neoplasms, which directly addresses a pathological condition to improve patient health.
No
Explanation: The device is a stent system designed for the palliation of malignant neoplasms in the biliary tree, which is a therapeutic rather than a diagnostic function. It is used to maintain patency of strictures, not to identify or characterize them.
No
The device description clearly details a physical stent made of stainless steel and a delivery system consisting of a catheter and balloon, indicating it is a hardware medical device.
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 the diagnosis, treatment, or prevention of disease.
- Device Description: The provided text describes a metallic stent and its delivery system designed to be implanted directly into the biliary tree to maintain patency. This is an implantable medical device used for a therapeutic purpose (palliation of malignant neoplasms).
- Intended Use: The intended use is "palliation of malignant neoplasms in the biliary tree." This is a treatment or management indication, not a diagnostic one based on analyzing specimens outside the body.
The device is used in vivo (within the living body) for a therapeutic intervention, not in vitro (in glass, or outside the body) for diagnostic testing.

Stent
The Express Biliary SD stent is a balloon expandable metallic stent intended to maintain patency of biliary strictures produced by malignant neoplasms. The stent will be available in a variety of sizes to address clinician needs.
The Express Biliary SD stent is made from 316L surgical grade stainless steel. The stent geometry is a laser-cut pattern consisting of large and small sinusoidal bands connected by axial struts. Additional struts are provided to reinforce the three connector rows of the proximal stent end, resulting in additional scaffolding designed to reduce tumor in-growth at the proximal stent end.
Delivery System
The delivery system for the Express Biliary SD Premounted Stent System consists of a Monorail™ catheter with a stent crimped on a balloon near the distal tip. The balloon is designed to provide an inflatable segment of known diameter and length at recommended pressures. The distal segment of the balloon catheter is dual lumen and coaxial. The outer lumen is used for inflation of the balloon. The wire lumen permits the use of guidewires (≤0.018 in / 0,46 mm) to facilitate advancement of the catheter to and through the stricture to be dilated.

§ 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. Burns:
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.

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).
