The description focuses on the mechanical properties and function of a physical stent, with no mention of software, algorithms, or AI/ML terms.
Yes
Explanation: The device is indicated for palliative treatment of malignant neoplasms, which is a therapeutic purpose.
No
This device is described as a stent used for palliative treatment, not for diagnosing conditions.
No
The device description clearly states it is a "balloon expandable stainless steel stent" and describes its physical properties and how it is used with a balloon catheter. This indicates it is a physical medical device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices 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 (in vitro).
- Device Description: The IntraStent™ Biliary Stent is a physical implantable device designed to be placed inside the body (in vivo) to treat a medical condition (malignant neoplasms in the biliary tree). It does not involve testing specimens taken from the body.
The information provided clearly describes a therapeutic device used within the body, not a diagnostic test performed on samples outside the body.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench tests were performed to verify that the IntraStent™ met the same performance characteristics as the predicate ITI Stent (K980290). Pyrogenicity testing performed on a lot to lot basis supports the nonpyrogenic claim.

(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)
unmounted, additionally the predicate Palmaz™ stent can be provided premounted on a PTA balloon catheter. For the unmounted stent, the Palmaz™ stent offers a separate nonsterile crimping tool while the ITI product does not. Both the IntraStent™ and predicate stents include 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™ met the same performance characteristics as the predicate ITI Stent (K980290). Pyrogenicity testing performed on a lot to lot basis supports the nonpyrogenic claim.
The IntraStent™ is substantially equivalent to the currently marketed ITI Stent and the Cordis Corporation/Johnson & Johnson PALMAZTM, PALMAZ-SCHATZ™, and PERFLEX™ Balloon-Expandable Biliary Stent as a palliative treatment for malignant strictures of the biliary tree. As demonstrated the IntraStent™ 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.
