No
This device is a pedicular fixation system intended for posterior, non-cervical fixation as an adjunct to fusion. It is a surgical implant system designed to provide immobilization and stabilization of spinal segments, not to diagnose medical conditions.
No
The device description explicitly details physical components made of titanium alloy (screws, rods, connectors) intended for surgical implantation. There is no mention of software as a component of the device itself.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The Spineology Threshold™ Pedicular Fixation System is a collection of implants (screws, rods, connectors) made of titanium alloy. These are surgically implanted into the patient's spine.
- Intended Use: The intended use is for posterior, non-cervical fixation as an adjunct to fusion in skeletally mature patients for various spinal conditions. This involves physically stabilizing the spine, not performing diagnostic tests on bodily samples.
The device is a surgical implant used for structural support and stabilization within the body, which is fundamentally different from an in vitro diagnostic device.
