No

The Cortera™ Spinal Fixation System is described as a "thoracolumbosacral pedicle screw system" intended for "immobilization and stabilization of spinal segments as an adjunct to fusion." Its components include screws, rods, and connectors used in surgical procedures. This description indicates it is a therapeutic device, not a diagnostic one.

No

The device description explicitly states it consists of screws, rod-to-rod connectors, lateral offset connectors, rods, locking set screws, and associated reusable manual surgical instruments, all of which are physical hardware components.

Based on the provided text, the Cortera™ Spinal Fixation System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD devices are used to examine specimens from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
  • The Cortera™ Spinal Fixation System is a surgical implant intended for posterior spinal fixation. It is a physical device implanted into the body to stabilize the spine.
