No
The device description focuses on the physical structure and deployment mechanism of a stent, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes
The device is intended for use in the treatment of tracheobronchial strictures and fistulas, which is a therapeutic purpose.
No
This device is a prosthesis intended for treatment (maintaining or increasing luminal diameter), not for diagnosing strictures or fistulas.
No
The device description clearly states it is a physical prosthesis constructed of biomedical superalloy and an elastomeric polymer, and is delivered via a physical delivery system.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to treat tracheobronchial strictures and fistulas by physically opening or maintaining the airway. This is a therapeutic intervention performed directly on the patient's body.
- Device Description: The device is a physical prosthesis (stent) that is implanted into the tracheobronchial passage. It is a mechanical device designed to provide structural support.
- Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not interact with or analyze such specimens.
The device is a medical device used for treatment, not for in vitro diagnostic testing.

Device Description
The Wallstent Tracheobronchial Endoprosthesis is a self-expanding prosthesis constructed of biomedical superalloy and an elastomeric polymer. Smaller diameter models may utilize a radiopaque core. The prosthesis is a braided wire structure which may be covered with an elastomeric polymer in selected models. The outward radial force along with the ends of the device serve to stabilize the prosthesis after implanted. The prosthesis is offered in covered and uncovered version to allow physicians to select the most appropriate models based on their preference and individual patient condition. The stents purpose is to increase or maintain the inner luminal diameter of the tracheobronchial passage.
The stent is placed by means of a delivery system. The delivery system is a coaxial tubing assembly which constrains the prosthesis until it is release in a controlled manner. The release of the stent is accomplished by retracting the outer sheath. The prosthesis is packaged constrained on the delivery system ready for placement. The system is sterile and intended for single use only.

§ 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.”

Trade/Device Name: WALLSTENT® Tracheobronchial Endoprosthesis Regulation Number: 21 CFR 878.3720 Regulation Name: Tracheal prosthesis Regulatory Class: II Product Code: JCT Dated: April 18, 1996 Received: April 19, 1996
Dear Ms. Byland:
This letter corrects our substantially equivalent letter of July 10, 1996.
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.
This letter will allow you to continue 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.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html
