Device Description
The MAGEC Spinal Bracing and Distraction System is comprised of a sterile single use spinal rod that can be surgiclly implanted using appropriate 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 nonsterile 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 actuator can be turned noninvasively 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 implanted magnet to rotate and distract the MAGEC rod. 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 (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical testing on the MAGEC System was performed to evaluate MRI compatibility in 1.5T clinical scanners. Due to the presence of a permanent magnet in the device. the ASTM standards were applied where possible and custom setups were developed and utilized in order to conduct the evaluations. Test samples were provided in the final manufactured condition and were evaluated for magnetically induced displacement force and torque. MR image artifact, radiofrequency induced heating, and design verification. Results of these testing indicated that, in accordance with relevant ASTM standards, MR Conditional labeling is appropriate.
Previous clinical performance data for the predicate MAGEC System are applicable to this MAGEC System. 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.

- Substantial equivalence: Documentation that includes mechanical test results, design verification 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) ●
Substantial equivalence to the predicate device is based on indications for use, principles of operation, technological characteristics, and pre-clinical testing performed.
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. The purpose of the premarket notification is only to revise the labeling from MR Unsafe to MR Conditional.
Non-clinical testing on the MAGEC System was performed to evaluate MRI compatibility in 1.5T clinical scanners. Due to the presence of a permanent magnet in the device. the ASTM standards were applied where possible and custom setups were developed and utilized in order to conduct the evaluations. Test samples were provided in the final manufactured condition and were evaluated for magnetically induced displacement force and torque. MR image artifact, radiofrequency induced heating, and design verification. Results of these testing indicated that, in accordance with relevant ASTM standards, MR Conditional labeling is appropriate.
The FDA guidance document "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment (12/11/2014)" was utilized to determine the specific non-clinical tests required to establish the labeling revision from MR Unsafe to MR Conditional:
| Test Description | Applicable Test Standard |
|---|---|
| Magnetically Induced Displacement Force | ASTM F2052 |
| Magnetically Induced Torque | ASTM F2213 |
| MR Image Artifact | ASTM F2119 |
| Radiofrequency Induced Heating | ASTM F2182 |
| Design Verification | None |
Additional non-clinical tests that were performed on the predicate MAGEC System are also applicable to the subject MAGEC System with the MR Conditional labeling change. There are no changes being made to the ERC, the MAGEC Manual Distractor and the MAGEC Wand Magnet Locator as a result of this submission, therefore all testing that was performed on the predicate MAGEC System for those components are applicable to the MAGEC System subject of this premarket notification.

The logo features a purple and silver abstract shape on the left, followed by the word "NUVASIVE" in silver, and the words "SPECIALIZED ORTHOPEDICS, INC." in purple below. The logo is clean and modern, and the colors are eye-catching.
Previous clinical performance data for the predicate MAGEC System are applicable to this MAGEC System. 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.
9. Conclusion:
Conclusions can be drawn from these tests that the MAGEC System is substantially equivalent to the predicate device.
