Yes
The device is intended to treat severe progressive spinal abnormalities and thoracic insufficiency syndrome, which are medical conditions, and aims to restore normal respiration and lung growth.
No
The device is described as a "Spinal Bracing and Distraction System" intended to brace the spine, minimize scoliosis progression, and facilitate distraction (lengthening) of an implanted rod. Its purpose is therapeutic/interventional, not diagnostic.
No
The device description clearly outlines multiple hardware components including a surgically implanted spinal rod, an External Remote Controller (ERC), a Manual Distractor, and a Wand Magnet Locator.
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 Function: The MAGEC Spinal Bracing and Distraction System is a surgically implanted device used to mechanically brace and distract the spine. It is a physical implant and external controller used for treatment and management of a physical condition.
- No Biological Sample Analysis: The description does not mention any analysis of biological samples from the patient. The device interacts directly with the patient's spine.
Therefore, the MAGEC Spinal Bracing and Distraction System falls under the category of a medical device used for surgical and non-invasive treatment, not an in vitro diagnostic device.

Device Description
The MAGEC Spinal Bracing and Distraction System is comprised of a sterile single use spinal rod that can be surgically implanted using appropriate NuVasive® and Armada® fixation components, or Stryker® Xia® fixation components (i.e. pedicle screws, hooks and/or connectors). The implanted MAGEC rod is used to brace the spine during growth to minimize the progression of scoliosis. The system includes a non-sterile hand held External Remote Controller (ERC or ERC 2) that is used periodically after implantation to non-invasively distract the implanted spinal rod. The titanium MAGEC rod includes an actuator portion that holds a small internal magnet. The magnet in the actuator can be turned non-invasively by use of the ERC, which is electrically powered. The hand held non-invasive ERC is placed over the patient's spine and then manually activated, which causes the magnet within the implanted MAGEC rod to rotate and distract. Once the physician determines that the implant has achieved its intended use and is no longer required, the implant is explanted. Additional accessories for the MAGEC System include the MAGEC Manual Distractor and the MAGEC Wand Magnet Locator. The MAGEC Manual Distractor is a sterile, single use device, which is used in the operating room to test the MAGEC rod prior to implantation. The MAGEC Manual Distractor used with the MAGEC System is made of Radel® and contains a rare-earth magnet. The MAGEC Wand Magnet Locator is a non-sterile device which is used during the distraction procedure to locate the magnet within the MAGEC rod. The ERC is placed over this location on the child's back.

Summary of Performance Studies
The safety and probable benefit of the predicate MAGEC System was evaluated outside the United States in a retrospective clinical study for children who had either a primary or revision spinal bracing procedure using the MAGEC System. In assessing probable benefit, the endpoints chosen in the study included Cobb angle correction in the coronal plane, thoracic spine height increase, improvement in space available for lung (SAL), coronal and sagittal balance, reduction in the number of subsequent surgical procedures, and weight gain.
The results of the clinical study showed the MAGEC System provides the benefits of spinal deformity correction and continued growth, similar to that for traditional growing rods, without the need for regular surgical lengthening procedures in these children. As with traditional growing rods, the MAGEC System provides direct bracing to the spine. This bracing provides for correction and maintenance of the scoliotic curve as defined by the Cobb Angle. In addition, a return to a more normal symmetry of the thoracic cavity is provided as demonstrated by the space available for lung (SAL). While implantation of the MAGEC System shares many of the same risks and hazards associated with those of traditional growing rods, the MAGEC System offers the benefit of non-invasive adjustment to lengthen the implanted rod without the need to perform another surgery. The ability of the device to be adjusted non-invasively in length provides the ability of the spine to continue growing in these subjects and for the Thoracic Spine Height to increase with this growth.
Non-clinical testing on the MAGEC System was performed to evaluate compatibility with the worst-case pedicle screw system. Pyrogen testing was performed on the subject device to ensure it meets the pyrogen limit specifications for sterile implant devices.

§ 888.3070 Thoracolumbosacral pedicle screw system.
(a)
Identification. (1) Rigid pedicle screw systems are comprised of multiple components, made from a variety of materials that allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Such a spinal implant assembly consists of a combination of screws, longitudinal members (e.g., plates, rods including dual diameter rods, plate/rod combinations), transverse or cross connectors, and interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors).(2) Semi-rigid systems are defined as systems that contain one or more of the following features (including but not limited to): Non-uniform longitudinal elements, or features that allow more motion or flexibility compared to rigid systems.
(b)
Classification. (1) Class II (special controls), when intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra; degenerative spondylolisthesis with objective evidence of neurologic impairment; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). These pedicle screw spinal systems must comply with the following special controls:(i) Compliance with material standards;
(ii) Compliance with mechanical testing standards;
(iii) Compliance with biocompatibility standards; and
(iv) Labeling that contains these two statements in addition to other appropriate labeling information:

- Substantial equivalence: Documentation that includes mechanical test results and detailed comparison to the predicate device demonstrates that the MAGEC System is substantially equivalent to the following 510(k) cleared device:
- MAGEC Spinal Bracing and Distraction System (K150885)
The purpose of this premarket notification is to revise the labeling to include the NuVasive 5.5 mm Reline and Armada Pedicle Screw Systems. Substantial equivalence to the predicate device is based on indications for use, principles of operation and technological characteristics. The MAGEC System that is the subject of this premarket notification is identical to the predicate device and has the same indications for use. All design and technological characteristics remain the same. Non-clinical testing on the MAGEC System was performed to evaluate compatibility with the worst-case pedicle screw system. Pyrogen testing was performed on the subject device to ensure it meets the pyrogen limit specifications for sterile implant devices.
The FDA guidance document "Guidance for Industry and FDA Staff: Spinal System 510(k)s" was utilized to determine the specific non-clinical tests required to establish compatibility.

surgical lengthening procedures in these children. As with traditional growing rods, the MAGEC System provides direct bracing to the spine. This bracing provides for correction and maintenance of the scoliotic curve as defined by the Cobb Angle. In addition, a return to a more normal symmetry of the thoracic cavity is provided as demonstrated by the space available for lung (SAL). While implantation of the MAGEC System shares many of the same risks and hazards associated with those of traditional growing rods, the MAGEC System offers the benefit of non-invasive adjustment to lengthen the implanted rod without the need to perform another surgery. The ability of the device to be adjusted non-invasively in length provides the ability of the spine to continue growing in these subjects and for the Thoracic Spine Height to increase with this growth.
9. Conclusion:
Conclusions can be drawn from these tests that the MAGEC System with the modified labeling is substantially equivalent to the predicate device.
