The device description and intended use clearly define a mechanical implant system for spinal fixation. There is no mention of software, algorithms, or any technology that would suggest AI/ML capabilities.
Yes
The device is described as a "pedicle screw fixation system intended to provide immobilization and stabilization of spinal segments ... as an adjunct to fusion in the treatment of ... instabilities or deformities of the thoracic, lumbar and sacral spine." This directly addresses a medical condition and aims to restore function or provide support, which defines a therapeutic device.
No
The device is an implantable pedicle screw system used for fixation and stabilization of the spine as an adjunct to fusion, not for diagnosing medical conditions.
No
The device description explicitly states it is an "implant device made from a titanium alloy" and includes physical components like screws, rods, and instrumentation. This indicates it is a hardware medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Description: The provided text describes an implantable surgical device (pedicle screw system) used to stabilize the spine. It is physically implanted into the patient's body.
- Intended Use: The intended use is to provide immobilization and stabilization of spinal segments, not to perform diagnostic tests on biological samples.
The device is a surgical implant, not a diagnostic tool that analyzes samples outside the body.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing was not conducted as part of this submission. The only technological differences between the subject CapLOX II/TowerLOX Pedicle Screw System and the previously cleared CapLOX II/TowerLOX Pedicle Screw System are additions of new pedicle screw sizes and the associated instruments. These differences do not present any new issues of safety or efficacy because the screws do not represent a new worst-case for the mechanical integrity and do not represent sizes outside of the clinically accepted size ranges. The subject devices have the same indications for use and operational principles as the predicate devices.
