Intended Use
The Zilver® 581™ Biliary Stent is indicated for use in the palliation of malignant strictures (neoplasms) in the biliary tree.
Device Description
The Zilver® 518™ Biliary Stent is a self-expanding, nitinol stent designed for excellent radial strength and optimal flexibility. Constructed from a series of interconnected Z-shaped segments, the configuration of the stent conforms to the shape of the biliary system and provides circumferential scaffolding throughout the stent's length. The interconnected Z-shaped segments also keep foreshortening to a minimum. The Zilver® 518™ Biliary Stent comes preloaded in a 5 French delivery system. The stent is deployed with the use of a simple hand held device. The stent is currently available in unrestrained outer diameters of 4, 5, 6, 7, 8, 9 and 10 mm in lengths of 20, 30, 40, 50 and 60 mm. The 80 mm length stent is an addition to this product line.

No
The description focuses on the mechanical properties and deployment of a physical stent, with no mention of software, algorithms, or data processing that would indicate AI/ML.

Yes
The device is indicated for the "palliation of malignant strictures (neoplasms) in the biliary tree," which describes treating a medical condition rather than diagnosing it.

No

The device is a stent used for palliation of malignant strictures in the biliary tree, which is a therapeutic function, not a diagnostic one.

No

The device description clearly describes a physical, implantable stent made of nitinol, which is a hardware component. The summary also details performance studies related to the physical properties and deployment of the stent.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body.
  • Device Description: The Zilver® 581™ Biliary Stent is a physical implantable device designed to be placed inside the body (in the biliary tree) to open up blockages.
  • Intended Use: The intended use is to palliate malignant strictures in vivo (within the body).

The information provided clearly describes a medical device used for treatment within the body, not for laboratory testing of specimens.

Device Description

The Zilver® 518™ Biliary Stent is a self-expanding, nitinol stent designed for palliation of malignant neoplasm in the biliary tree. Constructed from a series of interconnected Z-shaped segments, this configuration provides excellent radial strength and optimal conformance to the shape of the biliary system and provides scaffolding throughout the stent's length. Along with radiopaque markers, the interconnected Z-shaped segments also keep foreshortening to a minimum.

The Zilver® 518™ Biliary Stent comes preloaded in a 5 French delivery system. The stent is deployed with the use of a simple hand held device. The stent is currently available in unrestrained outer diameters of 4, 5, 6, 7, 8, 9 and 10 mm in lengths of 20, 30, 40, 50 and 60 mm. The 80 mm length stent is an addition to this product line.

§ 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.
