No
The device description and performance studies focus on the physical characteristics and mechanical performance of a metallic stent, with no mention of AI or ML technologies.
Yes
The device is a stent used for palliative treatment of malignant neoplasms, indicating it is used to manage disease symptoms and improve quality of life, which is a therapeutic purpose.
No
The device is a stent used for palliative treatment, which is a therapeutic intervention, not a diagnostic one. It does not identify or characterize diseases.
No
The device description clearly states it is a balloon expandable stainless steel stent, which is a physical hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "as a palliative treatment for malignant neoplasms in the biliary tree." This describes a therapeutic intervention performed within the body, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The device is a "balloon expandable stainless steel stent" designed to be implanted in the biliary tree. This is a medical device used for treatment, not for in vitro testing.
- Lack of IVD Characteristics: The description does not mention any components or processes related to analyzing biological samples (blood, urine, tissue, etc.) outside of the body, which is the defining characteristic of an IVD.
Therefore, the IntraStent™ DoubleStrut™ LD Biliary Stent is a therapeutic medical device, not an in vitro diagnostic device.

Device Description
The IntraStent™ DoubleStrut™ LD is a balloon expandable stainless steel stent with an I ne intrablem - Dozetter is provided unmounted, to be manually crimped onto a open natiliant PTA balloon catheter for biliary stent expansion of choice by the physician. Upon balloon inflation the crimped stent expands to conform to the duct inner luminal surface and retains the expanded state upon balloon deflation.
Summary of technological characteristics: The IntraStent™ DoubleStrut™ LD provides a larger version the IntraStent™ DoubleStrut™ (K991929), allowing an expanded diameter of 9-12 mm. The IntraStent™ devices are balloon expandable stents fabricated by cutting an engineered series of slots/apertures into a 316L stainless steel hypotube. The cuts are made with a laser. The IntraStent™ devices are cleaned, electro-polished, packaged in a double sterile barrier and sterilized. The IntraStent™ devices are ethylene oxide sterilized and are provided unmounted.
The IntraStent™ devices incorporate the use of manual compression using one's thumbs and forefingers to compress the stent onto the delivery balloon catheter.

§ 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.

510K Summary (Page 2 of 2)
The IntraStent™ devices incorporate the use of manual compression using one's thumbs and forefingers to compress the stent onto the delivery balloon catheter.
Bench tests were performed to verify that the IntraStent™ DoubleStrut™ LD met the same performance characteristics as the predicate IntraStent™ DoubleStrut™ (K991929). Pyrogenicity testing performed on a lot to lot basis supports the nonpyrogenic claim.
The IntraStent™ is substantially equivalent to the currently marketed IntraStent™ DoubleStrut™ and the Cordis Corporation/Johnson & Johnson PALMAZ™, and PALMAZ-SCHATZ™ Balloon-Expandable Biliary Stents as a palliative treatment for malignant strictures of the biliary tree. As demonstrated the IntraStent™ LD is identical in materials, indication for use, and technological characteristics. Performance testing (bench) further supports a substantial equivalence claim. The collective evidence therefore provides assurance that the IntraStent™ meets the requirements that are considered acceptable for the intended use.
