No
The device description and performance studies focus on the mechanical properties and delivery system of a stent, with no mention of AI or ML.
Yes
The device is described as a "Tracheobronchial Endoprosthesis" intended for "treatment of tracheobronchial strictures produced by malignant neoplasms," indicating its therapeutic purpose to alleviate a medical condition.
No
The device is a Wallstent Tracheobronchial Endoprosthesis, which is a self-expanding prosthesis intended for treatment of tracheobronchial strictures or fistulas, not for diagnosis.
No
The device description clearly details a physical, implantable prosthesis made of biomedical superalloy and polymer, along with a delivery system. There is no mention of software as the primary or sole component of the device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The Wallstent Tracheobronchial Endoprosthesis is an implantable medical device. Its purpose is to physically open or maintain the diameter of the tracheobronchial passage within the body. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states it's for the "treatment of tracheobronchial strictures or fistulas produced by malignant neoplasms." This is a therapeutic intervention, not a diagnostic test performed on a sample.
- Device Description: The description details a physical prosthesis and a delivery system for implantation. There is no mention of reagents, analyzers, or any components typically associated with IVD testing.
Therefore, based on the provided information, the Wallstent Tracheobronchial Endoprosthesis is a therapeutic medical device, not an In Vitro Diagnostic device.

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.

Dear Ms. Byland:
This letter corrects our substantially equivalent letter of December 4, 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
