No
The device description focuses on the mechanical components and materials of a stent delivery system and stent, with no mention of software, algorithms, or data processing that would indicate AI/ML. The "Mentions AI, DNN, or ML" field is also explicitly marked as "Not Found".
Yes
Explanation: The device is intended for "palliation of malignant strictures in the biliary tree," which is a therapeutic purpose.
No
The device is described as a stent system intended for the "palliation of malignant strictures in the biliary tree," which is a treatment, not a diagnostic, function.
No
The device description clearly details physical components like catheters, stents made of Nitinol, handles, and luer fittings, indicating it is a hardware-based medical device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "palliation of malignant strictures in the biliary tree." This describes a therapeutic intervention performed within the patient's body to treat a condition.
- Device Description: The description details a stent system designed to be deployed into the biliary tree. This is an implantable medical device used for structural support and opening of a blocked passage.
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens (like blood, urine, or tissue) outside of the body to provide information for diagnosis, monitoring, or screening.
This device is clearly designed for use in vivo (within a living organism) for a therapeutic purpose, not for analyzing samples in vitro.

Device Description
The 12 mm and 14 mm DYNALINKING Stent Systems are catherers designed to deploy a selfexpanding nickel titanium (Nitinol) stent into the biliary tree.
The catherer body is constructed from two coaxial members. The inner member (IM) is comparible with a 0.035" guide wire in an over the wire configuration. The outer member (OM) is composed of a distal sheath that constrains the unexpanded stent, an outer shaft over most of the catheter length, and a proximal handle used to retract the assembly,
The distal end of the delivery system includes either the 12 mm or the 14 mm DYNALINK™ Stent held in its constrained state by the stem-restraining sheath, a soft, low profile tip, and two radio-opaque markers to indicate the proximal and distal ends of the stent. At the proximal end of the delivery system. the user interface is composed of a pull-back handle attached to the OM, a shaped housing that allows the handle to slide axially, and a luer firting that is rigidly fixed to the shaped housing.
The 12 mm and 14 mm DYNALINK™ Stents are fabricated from superclastic nickel-titanium (niunol) in a series of serpentine rings that are aligned along a common longitudinal axis.
The stent is laser cut from a tube of superelastic minnol. All of the stent diameters are cut with similar stent patterns, and the stent is expanded and heat-treated to be stable at the desired final diamerer. The stens are electropolished to obtain a smooth finish with a thin layer of itanium oxide on the surface.

§ 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.

Summary of Substantial Equivalence:
The design, materials, method of delivery and intended use features of 12 mm and 14 mm DYNALINKIN Stem Systems are substantially equivalent with regard to these features in the predicate device, the DYNALINK ,018 Biliary Self-Expanding Steat System (K014007, January 7, 2002). The 12 mm and 14 mm DYNALINK To Stent Systems will be marketed as part of the DYNALINK . 035 Biliary Self-Expanding Stem System product line.

Indications for Use:
The DYNALINK . 018 Biliary Self-Expanding Stent System and the DYNALINK™ .035 Biliary Self-Expanding Stent System are intended for palliation of malignant strictures in the biliary tree.
Technological Characteristics:
Comparisons of the new and predicate devices show that technological characterissics such as materials, biocompatibility, performance properties, sterilization and packaging are substantially equivalent to the currently marketed predicate device. The design modifications of the new biliary stent systems compared to that of the predicate biliary stent system is the diameter of the stent, a system length of 55 cm, and dimensional changes to the delivery catheter. Manufacturing process changes, including a modification to a material coating, have also been made. These devices will be available in stent diamerers of 12 mm with stent lengths of 38, 56, and 80 mm for system lengths of 55, 80, and 120 cm and will have compatibility with 7F sheaths and 9F guiding catherers.
Performance Data:
The safery and effectiveness of the 12 mm and 14 mm DYNALINK™ Stent Systems have been demonstrated through data collected from in vitro bench tests and analyses.

Dear Dr. Murari:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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.
