No
Explanation: The device, the GT Metabolic MagDI System, is intended for use in the creation of side duodeno-ileal anastomoses. It is a surgical tool used to join two parts of the intestine, not to diagnose a condition.
No
The device description clearly states it is a set of two physical magnets, which are hardware components. The summary also details preclinical testing related to the physical properties of the magnets (field strength, separation forces, connection/disconnection) and biocompatibility, further indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the creation of surgical anastomoses (connections between two parts of the intestine) in minimally invasive and laparoscopic surgery. This is a surgical procedure performed on the body, not a test performed on a sample taken from the body.
- Device Description: The device is a set of magnets used to create a compression anastomosis. This is a physical device used during surgery.
- Lack of IVD Characteristics: There is no mention of the device being used to test a biological sample (blood, urine, tissue, etc.) to provide information about a patient's health status, disease, or condition.
IVD devices are used to perform tests in vitro (in glass, or outside the body) on samples to diagnose, monitor, or screen for diseases or conditions. This device is used in vivo (in the body) during a surgical procedure.
