No
The description focuses on the mechanical components and materials of a spinal fixation system and does not mention any software, algorithms, or AI/ML capabilities.

Yes
The device is a medical implant intended to provide immobilization of spinal segments as an adjunct to fusion for treating various spinal instabilities or deformities, which aligns with the definition of a therapeutic device.

No

The device is a pedicle screw system intended for spinal fixation and immobilization as an adjunct to fusion, not for diagnosing medical conditions.

No

The device description explicitly states that the system consists of physical implants (pedicle screws, rods, locking elements) and instruments, which are hardware components.

Based on the provided information, the Mariner Pedicle Screw System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD Definition: In vitro diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
  • Mariner Pedicle Screw System Function: The description clearly states that the Mariner Pedicle Screw System is a spinal fixation device and instrumentation system. It is implanted into the body to provide structural support and immobilization of spinal segments.
  • Intended Use: The intended use is to treat spinal instabilities and deformities by providing immobilization as an adjunct to fusion. This is a surgical intervention, not a diagnostic test performed on a specimen outside the body.
  • Device Description: The description details the physical components of the system (screws, rods, locking elements) and the materials they are made from. This aligns with a surgical implant, not a diagnostic device.

Therefore, the Mariner Pedicle Screw System falls under the category of a surgical implant or medical device used for treatment, not an in vitro diagnostic device.
