The device description and performance studies focus on the mechanical properties and equivalence to predicate devices, with no mention of AI or ML.
Yes.
The device is intended as a palliative treatment for malignant neoplasms, which is a therapeutic purpose.
No
Explanation: The device is a stent intended for palliative treatment of malignant neoplasms in the biliary tree, which is a therapeutic function rather than a diagnostic one.
No
The device description clearly states it is a "balloon expandable stainless steel stent," which is a physical 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 a "palliative treatment of 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.
- 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 diagnosing a condition by analyzing a sample.
- 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 samples
- Providing information for diagnosis, monitoring, or screening
Therefore, the IntraStent® Mega™ LD and IntraStent® Max™ LD Stents are therapeutic medical devices, not In Vitro Diagnostics.

Device Description
The IntraStent Mega and Max LD Stents are balloon expandable stainless steel stents with an open lattice design. The device is provided unmounted, to be manually crimped onto a noncompliant 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.
The IntraStent Mega and Max LD stents provide a larger version the IntraStent™ Stent (K991929), allowing expanded diameters of 9-12mm and 12mm. 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.

This summary is provided in compliance with section 513(I)(3)(A) of the Act and
summarizes the safety and effectiveness information contained in this premarket notification submission for a modification to the IntraStent® Stent.
The IntraStent Mega and Max LD stent are intended as a palliative treatment of malignant neoplasms in the biliary tree.
The IntraStent Mega and Max LD Stents are balloon expandable stainless steel stents with an open lattice design. The device is provided unmounted, to be manually crimped onto a noncompliant 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 Mega and Max LD stents provide a larger version the IntraStent™ Stent (K991929), allowing expanded diameters of 9-12mm and 12mm. 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.

IntraStent Mega and Max LD Special 510(k): Device Modification
510K Summary (continued)
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 Mega and Max LD stents met the same performance characteristics as the predicate IntraStent™ Stent (K991929).
The IntraStent is substantially equivalent* to the currently marketed IntraStent stent (K991929) and the IntraStent DoubleStrut LD (K993904) as a palliative treatment for malignant strictures of the biliary tree. As demonstrated, the modified IntraStent 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 IntraStent® Mega™ LD and IntraStent® Max™ LD meet the requirements that are considered acceptable for the intended use.
*This document uses the term "substantial equivalence" as intended in 21 CFR 807.87, and not as defined in Title 36 of the US Code.

Dear Mr. Smythe:
We have reviewed your Section 510(k) notification of intent to market the devices referenced above and we have determined the devices are substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the devices, subject to the general controls provisions of the Act and the limitations described below. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
The Office of Device Evaluation has determined that there is a reasonable likelihood that these devices will be used for an intended use not identified in the proposed labeling and that such use could cause harm. Therefore, in accordance with Section 513(i)(1)(E) of the Act, the following limitation must appear in the Warnings section of the devices' labeling:
The safety and effectiveness of this device for use in the vascular system have not been established.
Furthermore, the indication for biliary use must be prominently displayed in all labeling, including pouch, box, and carton labels, instructions for use, and other promotional materials, in close proximity to the trade name, of a similar point size, and in bold print.
