No
The description focuses on the mechanical properties and design of a physical stent and delivery system. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is a therapeutic device because its intended use is for the "treatment of tracheobronchial strictures caused by malignant neoplasms."
No
The device is a Tracheal Stent System, indicated for the treatment of tracheobronchial strictures, which means its primary function is therapeutic, not diagnostic.
No
The device description clearly details a physical, implantable metallic stent and a flexible delivery system, indicating it is a hardware medical device, not software-only.
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, tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- Device Description and Intended Use: The provided information clearly describes a device that is implanted directly into the tracheobronchial tree to treat strictures. This is an in vivo procedure (performed inside the body).
- Lack of Specimen Testing: There is no mention of this device being used to test any biological specimens. Its function is mechanical support and expansion within the airway.
Therefore, based on the provided information, the Tracheal Stent System (Y-Shaped) is a therapeutic medical device used for direct treatment within the body, not an in vitro diagnostic device.

Intended Use / Indications for Use

Device Description
The Tracheal Stent System (Y-Shaped) consists of a flexible delivery system preloaded with a self-expanding implantable metallic stent. The stent is made of Nitinol wire by weaving in a Y shaped. This structure design can make the stent more flexible, compliant and self-expanding. The stent is integrated Y-shaped stent, which include 1 main stent, 2 branch stents, the integrated Y-shaped stent can replace three straight shape stents, and the overall design of Y-shaped stent can also be used for the expansion of the carina if there are strictures at the carina. The stent is woven from Nitinol wire. The branch stent is formed with a flange at either end. The stent is partially covered with silicone to restrict tumor in-growth through the wire mesh. To aid in visibility under fluoroscopy there are radiopaque markers at the stent. There are 3 retrieval loops at the end of stent which can be used to reposition the stent during the initial placement procedure if desired. The device is supplied sterile, intended for single use only and is available for prescription use only. Use of this device is restricted to a trained healthcare professional.

Section 5 510k summary
The proposed device Tracheal Stent System (Y-Shaped) is similar in design and dimension to TRACHEOBRONXANE™ DUMON Tracheo-bronchial Silicone Stent (K971509), both stents are Y -shaped stents, the diameter and length of stent is not exactly the same, but they are very similar, all the performances required for different dimension have been tested and meet the requirement; The proposed device consists of a flexible delivery system preloaded with the stent, the stent is woven from nitinol wire and a silicone covered. The predicate device only has a silicone Y stent, doesn't include delivery system. For the differences, we choose AERO™ Tracheobronchial Stent Technology System (K140382) as a reference device which consists of a flexible delivery system preloaded with the stent and the stent is nitinol stent and covered with a membrane, the related comparative performance testing to the reference device have been conducted, the test results meet the requirement. The proposed device is EO sterilized and have a two-years shelf life, the predicate device is sterilized and have a five-years shelf life. After EO sterilized and aging, the bench testing and sterility testing of proposed device meet the requirement.
Therefore, the difference between proposed device and predicated device is considered not to affect the Substantially Equivalency between the proposed and predicate devices concerning the safety and effectiveness.
