Yes.
The TSRH® Spinal System is intended to help provide immobilization and stabilization of spinal segments as an adjunct to fusion for various spinal conditions, fitting the definition of a therapeutic device.
No
Explanation: The device is described as a "pedicle screw fixation system" and "Spinal System" intended to provide "immobilization and stabilization of spinal segments as an adjunct to fusion." It is a surgical implant designed for treatment, not diagnosis. The indications for use consistently describe conditions that the device helps to treat or stabilize, not diagnose.
No
The device description explicitly lists various hardware components like rods, hooks, screws, plates, etc., and describes their materials and intended use in spinal fixation. There is no mention of software as the primary or sole component.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Description and Intended Use: The description clearly states that the TSRH® Spinal System is a system of implants (rods, hooks, screws, etc.) intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion. This is a surgical implant used directly within the body, not a device for testing specimens outside the body.
- Lack of IVD Characteristics: The text does not mention any aspects related to specimen collection, analysis of biological samples, or providing diagnostic information based on such analysis.
Therefore, the TSRH® Spinal System is a surgical implant, not an In Vitro Diagnostic device.
