The summary describes a mechanical stent and delivery system with no mention of AI/ML terms, image processing, or data-driven performance metrics.
Yes
Explanation: The device is intended for maintaining esophageal lumen patency in esophageal strictures and for occlusion of esophageal fistulae, which are therapeutic interventions.
No
The device is an esophageal stent system used for maintaining patency and occluding fistulae, which are therapeutic functions, not diagnostic.
No
The device description explicitly states it is comprised of a Nitinol stent (hardware) and a delivery system (hardware). It is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to maintain esophageal lumen patency and occlude esophageal fistulae. This is a therapeutic intervention performed in vivo (within the body) to treat a physical condition.
- Device Description: The device is a stent and a delivery system, designed to be implanted in the esophagus.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, tissue, etc.) to provide information for diagnosis, monitoring, or treatment.
IVDs are typically used to perform tests on samples outside the body to gain diagnostic or other medical information. This device is a medical device used for direct treatment within the body.

The Alveolus ALIMAXX-E™ Esophageal Stent System is comprised of two components: the completely covered, self-expanding Nitinol stent and the delivery system. The ALIMAXX-E™ Esophageal Stent System is available in several diameters and lengths.
The single-patient-use components of the ALIMAXX-E™ Esophageal Stent System are provided non-sterile.
Intended Use (Indications)
The Alveolus ALIMAXX-E™ Esophageal Stent System is intended for maintaining esophageal lumen patency in esophageal strictures caused by intrinsic and / or extrinsic malignant tumors. The stent is also indicated for occlusion of esophageal fistulae.
Substantial Equivalence
This Notice supports the position that the modified Alveolus ALIMAXX-E™ Esophageal Stent is substantially equivalent to the Alveolus ALIMAXX-E™ Esophageal Stent System [510(k) Number K051621].
Comparisons of the modified Alveolus ALIMAXX-E™ Esophageal Stent System and the ALIMAXX-E™ Stent System predicate device (K051621) show that technological characteristics such as materials, biocompatibility, performances properties, sterilization and packaging are substantially equivalent to the currently marketed predicate device. Physical test results were performed and i biocompatibility test results included tests recommended in FDA "Guidance for the Content of Premarket Notifications for Esophageal and Tracheal Prostheses" (issued on April 28, 1998).
Conclusions
Alveolus believes that the information provided establishes that similar legally marketed devices have been used for the same clinical applications as the subject device. The materials from which the Alveolus device is fabricated have an established history of use in clinical applications, and the devices produced by Alveolus have been tested in accordance with applicable FDA guidelines.

Dear Mr. Alexander:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations. Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally. marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
