No
The device description and performance studies focus on the mechanical properties and biocompatibility of a physical stent, with no mention of AI/ML or related concepts.
Yes
Explanation: The device is described as a "palliative treatment for malignant neoplasms in the biliary tree," indicating it is used to manage and relieve symptoms of a disease, which falls under the definition of a therapeutic device.
No
Explanation: The device description clearly states it is a "balloon expandable stainless steel stent" used as a "palliative treatment for malignant neoplasms." This indicates a therapeutic, not diagnostic, function.
No
The device description clearly states it is a "balloon expandable stainless steel stent," which is a physical hardware component.
No, 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, not a diagnostic test performed on samples outside the body.
- Device Description: The device is a stent, which is an implantable medical device used to open and maintain the patency of a lumen. This is a therapeutic device.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in those samples
- Providing information for diagnosis, monitoring, or prognosis
This device is a therapeutic medical device used for treating a condition within the body.

Device Description
IntraTherapeutics. Inc. device is a balloon expandable stainless steel stent with an open lattice design. The ITI Stent is provided unmounted to be manually crimped onto a noncompliant PTA balloon catheter 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 Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparison bench tests regarding performance characteristics were performed on the ITI and predicate stent to demonstrate equivalency. A biocompatibility assessment for cytotoxicity was performed on finished ITI product and determined noncytotoxic. Pyrogenicity testing performed on a lot to lot basis will support the nonpyrogenic claim.

§ 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 Preparation Date: January 23, 1998
This summary is provide in compliance with section 513(D(3)(A) of the Act and summarizes the safety and effectiveness information contained in this premarket notification submission.
The product trade and common name are ITI Stent and biliary catheter, respectively. This is a Class II product classified under 21 CFR §8768.5010 as a biliary catheter and accessories. Substantial equivalence is claimed to Cordis Corporation, legally marketed PALMAZTM and PALMAZ-SCHATZ™ Balloon-Expandable Biliary Stent (K905720, K911581, K964688).
IntraTherapeutics. Inc. device is a balloon expandable stainless steel stent with an open lattice design. The ITI Stent is provided unmounted to be manually crimped onto a noncompliant PTA balloon catheter 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.
The intended use is "as a palliative treatment for malignant neoplasms in the biliary tree".
Summary of technological characteristics: both products are balloon expandable stents fabricated by cutting an engineered series of slots/apertures into a 316L stainless steel hypotube. The ITI and predicate stent cuts are made with a laser. Both the ITI and predicate stent are cleaned, electro-polished, packaged in a double sterile barrier and sterilized. The ITI stent is ethylene oxide sterilized and the predicate stent CO60. The ITI and predicate stent are provided unmounted, additionally the predicate stent can be provided premounted on a PTA balloon catheter. For the unmounted stent, the predicate offers a separate non-sterile crimping tool while the ITI product does not. Both the TTI stent and predicate stent include use of manual compression using ones thumbs and forefingers to compress the stent onto the delivery balloon catheter.

IntraTherapeutics, Inc. Premarket Notification
510(k) Summary (Page 2 of 2)
Comparison bench tests regarding performance characteristics were performed on the ITI and predicate stent to demonstrate equivalency. A biocompatibility assessment for cytotoxicity was performed on finished ITI product and determined noncytotoxic. Pyrogenicity testing performed on a lot to lot basis will support the nonpyrogenic claim.
The ITI Stent is substantially equivalent to the currently marketed Cordis Corporation/Johnson & Johnson, legally marketed PALMAZ™ and PALMAZ-SCHATZ™ Balloon-Expandable Biliary Stent as a pailiative treatment for malignant strictures of the biliary tree. As demonstrated the ITI Stent 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 ITI Stent meets the requirements that are considered acceptable for the intended use.
