No
The device description focuses on the mechanical properties and geometry of the stent and delivery system. There is no mention of AI, ML, image processing, or any data-driven algorithms. The performance studies are based on physical and biocompatibility testing, not algorithmic performance.
Yes
The device is intended for the treatment of tracheobronchial strictures, which falls under the definition of a therapeutic intervention.
No
The device is a stent system used for treating strictures caused by malignant neoplasms, which is a therapeutic rather than a diagnostic function.
No
The device description clearly states it is comprised of a radiopaque stent (hardware) and a delivery system (hardware), and there is no mention of software as a component or the primary function.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Description and Intended Use: The Alveolus TB-STS™ Tracheobronchial Stent System is a physical implantable device (a stent) used to treat strictures in the tracheobronchial airways. It is directly inserted into the body to provide structural support and open the airway.
- Lack of Specimen Handling: The description and intended use do not involve the collection, preparation, or analysis of any specimens from the human body.
Therefore, based on the provided information, the Alveolus TB-STS™ Tracheobronchial Stent System is a therapeutic device, not an in vitro diagnostic device.

Intended Use / Indications for Use

Device Description
The Alveolus Tracheobronchial Stent Technology System is comprised of two components: the radiopaque stent and the delivery system. The nitinol stent is completely covered with a biocompatible polyurethane (ChronoFlex™) membrane and is self-expanding. The stent expansion results from the mechanical properties of the metal and the proprietary geometry. The stent is designed with a slightly larger diameter near the distal and proximal ends to minimize the possibility of migration. The stent ends are slightly vaulted inwardly in order to minimize the possible airway injury from the stent edges. The overall stent geometry is designed to maintain a constant length and has virtually no foreshortening, thus facilitating the selection of the appropriate stent.

§ 878.3720 Tracheal prosthesis.
(a)
Identification. The tracheal prosthesis is a rigid, flexible, or expandable tubular device made of a silicone, metal, or polymeric material that is intended to be implanted to restore the structure and/or function of the trachea or trachealbronchial tree. It may be unbranched or contain one or two branches. The metal tracheal prosthesis may be uncovered or covered with a polymeric material. This device may also include a device delivery system.(b)
Classification. Class II. The special control for this device is FDA's “Guidance for the Content of Premarket Notification Submissions for Esophageal and Tracheal Prostheses.”

Dear Mr. Canal:
This letter corrects our substantially equivalent letter of May 15, 2003.
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 (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 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. 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 (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050.
