The device description focuses on the mechanical properties and delivery system of a nitinol stent, with no mention of AI or ML capabilities.
Yes
Explanation: The device is indicated for palliation of malignant neoplasms in the biliary tree and is designed to maintain patency of biliary ducts obstructed by malignant neoplasms, which are therapeutic functions aimed at alleviating symptoms and improving patient conditions.
No
Explanation: The device is a stent system used for palliation of malignant neoplasms in the biliary tree, designed to maintain patency of obstructed biliary ducts. It is a therapeutic device, not a diagnostic one.
No
The device description clearly details a physical medical device (stent and delivery system) made of nitinol and other materials, with no mention of software as the primary or sole component.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The description clearly states that the Sentinol Nitinol Biliary Stent System is a physical device (a stent and delivery system) intended to be implanted within the body (in the biliary tree) to maintain patency of ducts.
- Intended Use: The intended use is for "palliation of malignant neoplasms in the biliary tree," which is a therapeutic intervention, not a diagnostic test performed on a sample outside the body.
The device is a therapeutic medical device, specifically an implantable stent system.

Device Description
The Sentinol Nitinol Biliary Stent System consists of a self-expanding, open mesh, laser cut nitinol stent that is loaded into a delivery system consisting of two coaxially arranged shafts. The delivery system is designed to deliver the stent to the stricture site via transhepatic access. Once positioned at the stricture site, the retractable exterior shaft is used to facilitate stent placement. Upon deployment, the stent expands and conforms to the inner lumen of the biliary duct. The stent is designed to maintain patency of biliary ducts which have been obstructed by malignant neoplasms.
The Sentinol Nitinol Biliary Stent is a self expanding 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 Sentinol Nitinol Biliary Stent is made from nitinol tubing. The seamless tubing is initially extruded to a cylindrical shape, and is then drawn down in a series of steps to the final tubing dimension. The stent is formed by laser cutting the pattern from the tube, after which it is cleaned and electropolished to obtain smooth rounded struts.
The Sentinol Nitinol Biliary Stent will be offered in various sized models with stent diameters ranging from 5 mm through 10 mm in one mm increments, and with stent lengths of 20 mm, 40 mm, 60 mm, and 80 mm.
The delivery system consists of two coaxially arranged shafts: an inner shaft and a retractable exterior shaft. The central lumen within the inner shaft continues to the tip and accepts a 0.035" guidewire through the distal tip that exits the proximal inner shaft hub.
The stent is loaded into the delivery system over the distal segment of the inner shaft. Two radiopaque marker bands on the inner shaft and one radiopaque marker band on the retractable exterior shaft are used to facilitate stent placement. The distal end of the exterior shaft covers the stent and is retracted to allow for stent deployment. The space between the coaxial inner shaft and the exterior shaft is accessed through the Y-manifold. The catheter models will be available in 75 cm and 135 cm working lengths.

(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. Kornmann:
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.
