The device is a spinal fixation system, intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion, which is a treatment, not a diagnostic process.
No
The device description explicitly states that the device is a "patient specific K-ROD" manufactured from Ti-6Al-4V ELI per ASTM F136, which is a physical hardware component. The performance studies also involve mechanical testing of this hardware.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a spinal fixation system used for surgical implantation to provide immobilization and stabilization of spinal segments. This is a therapeutic device, not a diagnostic one.
- Device Description: The device is described as a spinal fixation system component (patient specific K-ROD) made of titanium alloy, designed for surgical use. This aligns with a medical device for treatment, not diagnosis.
- Lack of Diagnostic Function: There is no mention of the device being used to examine specimens from the human body (like blood, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
- Performance Studies: The performance studies described are mechanical tests (ASTM F1717, ASTM F1798) to evaluate the structural integrity and compatibility of the spinal fixation components. These are typical tests for implantable medical devices, not IVDs.
In summary, the KHEIRON® Spinal Fixation System is a surgical implant used for treating spinal conditions, which falls under the category of a medical device, not an In Vitro Diagnostic device.
