Device Description
Internal Distraction - Sterile consists of sterile internal distraction devices intended for the correction of the mandible and mid-face bones that are comprised of several different designs and components intended for bone stabilization and elongation through distraction osteogenesis. It is composed of multiple sizes and shapes of distractor footplates and either fixed or detachable activator arms. The devices are positioned internally with a connected activation arm extending through the soft tissue for external activation. Some devices, due to their anatomical positioning, are directly activated using a patient activation driver, eliminating the need for attaching an activation arm to the device. The distractor footplates are fixated to the bone on either side of the osteotomy using previously cleared bone screws (K943347, K944561, K944565, K971297, K060177). Distraction is achieved by rotating the distractor threaded drive screws with the patient driver, often with an activation arm, which causes a separation of the distractor footplates and induces the body to grow bone and expand soft tissue as a response. Various lengths of distractor drive screws are available to achieve the desired distraction length. Upon completion of distraction and consolidation of the bone, the screws are removed from the footplates and the distractor is explanted.

Indications for Use
Internal Distraction - Sterile includes devices intended as bone stabilizers and lengthening (and or transport) devices for correction of congenital deficiencies or post traumatic defects of the mandible (including ramus, body, alveolar ridge, palate, symphysis) and mid-face bones that require gradual distraction.
Technological Characteristics/Substantial Equivalence Discussion
Similarities to Predicate Devices
Internal Distraction - Sterile is very similar to the predicate devices with respect to intended use, but identical in materials, manufacturing process, principles of operation, design mechanisms, and performance. Placement and fixation of the Internal Distraction - Sterile devices is identical to the methods used for the predicate devices.
Differences to Predicate Devices
Internal Distraction - Sterile differs from the predicate devices in that it will be provided in sterile packaging and will have different stock numbers from the originally cleared stock numbers to identify the product as sterile. In addition, the intended use differs slightly in that Internal Distraction - Sterile will be intended for correction of bones in the mandible and mid-face only, and will not include cranial bones.
Non-Clinical Performance Data
Biocompatibility Testing
Biocompatibility requirements were assessed in accordance with FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO 10993, "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process." as recognized by FDA. The patient-contacting materials Titanium Alloy (Ti-6Al-4V) and CP Titanium used for the Internal Distraction - Sterile devices and their components were tested for biocompatibility and are previously cleared in all predicate devices. The Internal Distraction - Sterile devices and their components are comprised of the same materials, have the same chemical composition, undergo the same manufacturing processes, and have the same body contact duration as these devices; therefore, biocompatibility testing for Internal Distraction - Sterile is not needed.
Endotoxin Testing
Bacterial Endotoxins testing was conducted in accordance to ANSI/AAMI ST72:2011, USP , and EP 2.6.14 for detection and quantitation of bacterial endotoxins. The results of the testing demonstrate that the subject devices conform to the required endotoxin units per device for medical devices and meet pyrogen limit specifications.

Performance Testing - Bench
Axial load testing, bending torsion testing, axial-torsion testing, and transverse shear testing were performed to evaluate the mechanical properties of the subject devices. All devices passed design requirements for material properties, manufacturing tolerances, axial resistance, and torsional loading. The results of the testing demonstrate the devices are sufficiently capable of withstanding the anatomical loads placed upon them and allow for effective and safe boney movement during their intended use.
Clinical Performance Data
Clinical testing was not necessary for the determination of substantial equivalence.
Conclusion
Internal Distraction - Sterile is very similar in its intended use, is identical in design, function, manufacturing process, and is composed of the same materials as the predicate devices. The similarities and differences in technological characteristics do not raise new questions of safety or effectiveness. Internal Distraction - Sterile will encompass all the previously cleared predicate devices intended for correction of mandible and mid-face bones and provide them sterile. Therefore, the information presented supports substantial equivalence of Internal Distraction - Sterile to the predicate devices.
