No
The description focuses on the physical construction and mechanical properties of the stent and delivery system, with no mention of AI or ML.
Yes
The device is used to maintain patency of malignant esophageal strictures and/or to seal tracheoesophageal fistulas, which are therapeutic interventions.
No
The device is a stent used to treat malignant esophageal strictures and tracheoesophageal fistulas by maintaining patency or sealing. Its purpose is therapeutic, not diagnostic, as it does not gather or process information about a patient's medical condition for diagnosis.
No
The device description clearly details a physical stent made of nitinol wire and silicone, along with an introducer system with catheters and a handle. This indicates a hardware-based medical device, not a software-only one.
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 patency of malignant esophageal strictures and/or to seal tracheoesophageal fistulas. This is a therapeutic intervention performed directly on the patient's body.
- Device Description: The device is a stent and an introducer system, designed for physical placement within 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, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used in vitro (outside the body) to analyze samples. This device is used in vivo (inside the body) for treatment.
N/A
Intended Use / Indications for Use
This device is used to maintain patency of malignant esophageal strictures and / or to seal tracheoesophageal fistulas.

Device Description
Stent Description: This flexible, self-expanding stent is constructed of nitinol wire with a silicone cover. The total length of the stent is indicated by radiopaque markers on the inner catheter, indicating the actual length of the stent at nominal stent diameter. There is a lasso at the proximal end of the stent whose purpose is to reposition the stent as needed.
Introducer System Description: The stent is mounted on an inner catheter, which accepts a 0.035 inch guidewire and is constrained by an outer catheter. A pistol-grip delivery handle allows stent deployment or rccapture.

§ 878.3610 Esophageal prosthesis.
(a)
Identification. An esophageal prosthesis is a rigid, flexible, or expandable tubular device made of a plastic, metal, or polymeric material that is intended to be implanted to restore the structure and/or function of the esophagus. The metal esophageal 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 Ms. Barry:
We have reviewed your Section 510(k) premarket notification of intent to market the device wo nave reviewed above and have determined the device is substantially equivalent (for the indications for rorerontou as vo allosure) 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 therefore, mance 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 (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your Approval), It they of cally of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
