No
The 510(k) summary describes a mechanical device (stent and delivery system) and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is described as an "esophageal stent system" intended for "maintaining esophageal luminal patency in esophageal strictures" and "occlusion of concurrent esophageal fistulas," which are therapeutic interventions.
No
The device is an esophageal stent system, intended for maintaining luminal patency in strictures and occluding fistulas, which is a therapeutic function, not a diagnostic one.
No
The device description explicitly states it consists of a self-expanding esophageal metal stent and a delivery system, which are physical hardware components.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description and Intended Use: The provided information clearly describes a physical device (a self-expanding metal stent and delivery system) intended to be implanted within the esophagus to maintain its opening and address fistulas. This is an implantable medical device used for treatment, not for testing samples outside the body.
The description focuses on the mechanical function and placement of the stent within the patient's body, which is characteristic of a non-IVD medical device.

Device Description
The Agile Esophageal Stent System consists of a self-expanding esophageal metal stent and a delivery system. The Agile Esophageal Stent is available partially or fully covered with silicone covering and in three diameter sizes: 14mm, 18mm and 23mm. The 14mm and 18mm diameter stents are pre-loaded on a 10.5Fr delivery system and the 23mm diameter stent is pre-loaded on an 18.5Fr delivery system. The 10.5Fr delivery system has a single central lumen to accommodate a 0.035" (0.89 mm) guidewire. The 18.5Fr delivery system has a single central lumen to accommodate a 0.038" (0.97mm) guidewire.

Summary of Performance Studies
Boston Scientific Corporation has demonstrated that the proposed Agile™ Esophageal Stent System are substantially equivalent to the previously cleared and currently marketed predicate Agile™ Esophageal Stent System (K180144 and K211960).
The proposed Agile Esophageal Stent System are identical to the predicate Agile Esophageal Stent System (K180144 and K211960) in intended use, indications for use, classification, principles of operation, technical characteristics, performance, and materials. The labeling changes do not raise different questions of safety and effectiveness. The testing performed on the proposed Agile™ Esophageal Stent System demonstrates the devices are substantially equivalent.

(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 Alexis Erazo:
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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
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.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
