No
The device description and intended use focus on a mechanical stent and delivery system, with no mention of AI or ML capabilities. The "Mentions AI, DNN, or ML" field is explicitly marked as "Not Found".
Yes
The device is indicated for "palliative treatment of gastroduodenal obstructions caused by malignant neoplasms," which directly addresses a disease condition for patient benefit.
No
Explanation: The device is a stent used for the palliative treatment of obstructions, which is a therapeutic rather than a diagnostic function.
No
The device description explicitly states it consists of an implantable metal stent and a delivery system, which are 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 (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside the body (in vitro).
- Device Description: The WallFlex™ Enteral Duodenal Stent is an implantable metal stent and a delivery system. It is designed to be placed inside the body to treat an obstruction.
- Intended Use: The intended use is for the "palliative treatment of gastroduodenal obstructions caused by malignant neoplasms." This is a therapeutic intervention performed inside the body, not a diagnostic test on a sample.
The device is a therapeutic device used for treatment, not a diagnostic device used for testing samples.

Device Description
The proposed WallFlex™ Enteral Duodenal Stent with Anchor Lock Delivery System consists of two components: an implantable metal stent and a delivery system. The proposed stent is manufactured of Nitinol and has a 22mm body diameter with a 27mm distal flare diameter, and is offered in three lengths, 6cm, 9cm, and 12cm. The Anchor Lock Delivery System consists of a coaxial tubing assembly that constrains the stent on the delivery catheter shaft until the stent is released by retracting the exterior tube.
