No
The device description focuses solely on the physical characteristics and mechanical function of a metallic stent. There is no mention of software, algorithms, data processing, or any terms related to AI/ML.
Yes
The device is indicated for the palliation of malignant strictures in the biliary tree, which is a therapeutic purpose. It is also described as a permanent implant used to treat these strictures.
No
The device is a stent, used for palliation of malignant strictures, which is a treatment rather than a diagnostic function.
No
The device description clearly states it is a physical stent fabricated from stainless steel tubing, designed for implantation. It is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "palliate malignant strictures in the biliary tree." This is a therapeutic intervention performed within the body to treat a physical condition.
- Device Description: The device is a "balloon-expandable stent designed to be placed percutaneously into the common bile duct." This describes a physical implant used for mechanical support.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used outside the body to analyze samples and provide diagnostic information. This device is used inside the body for treatment.

Device Description
The Guidant MEGALINK™ Biliary Stent is a balloon-expandable stent designed to be placed percutaneously into the common bile duct and intended to treat malignant strictures in the biliary tree. The stent is for single use only and is a permanent implant. The Guidant MEGALINKTM Biliary Stent is fabricated from a single piece of 316L medical grade stainless steel tubing which conforms to ASTM Standard F-138-92 Grade 2.
The stent is comprised of a scries of multiple rings with multiple links aligned along a common longitudinal axis. Each ring is approximately 2 mm long. The number of rings per stent is dependent upon the length of the stent, i.e., 8 rings for 18 mm, 13 rings for 28 mm and 17 rings for 38mm. The nominal strut thickness is .0060" and the nominal strut width is .00575". The stent is balloon-expandable with an expansion range from 6 - 10 mm in diameter for the 58 mm length stents. The stent is designed to be hand crimped onto a percutaneous transluminal angioplasty (PTA) balloon catheter for stent delivery and deployment in the biliary tree. The stent may be post dilated with a PTA balloon catheter to ensure good stent deployment. The maximum post dilatation diameter for the 58 mm stent length is 11 mm.

§ 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.

- Technological Characteristics:
Comparisons of the new and predicate devices show that technological characteristics such as materials, biocompatibility, performance properties, sterilization, and packaging are identical or substantially equivalent to the currently marketed predicate devices. The design modifications of the new guide wires compared to that of the predicate wire are the lengths of the stents.
- Technological Characteristics:
14. Performance Data:
In vitro bench testing was performed to demonstrate that the Guidant MEGALINK Biliary stent met the acceptance criteria and performed similar to the predicated evices. The functional tests met product specifications.
15. Conclusions
Since the new stent length have the same intended use, technological characteristics, performance properties, identical sterilization and packaging, process and no new safety or effectiveness issucs, the Guidant MEGALINKTM Biliary Stent ( 58 mm stent length) may be considered substantially equivalent to the predicate Guidant MEGALLNKTM Biliary Stent (18 mm, 28 mm, and 38 mm stent length),
