The provided 510(k) summary describes a mechanical external distraction device and contains no mention of AI, ML, image processing, or any data-driven algorithms.
No.
Explanation: The device is used for gradual bone distraction and lengthening of the midface in craniofacial surgery, which are reconstructive and surgical procedures, not therapeutic treatments for a disease.
No
Explanation: The device is described as an external distraction osteogenesis device used to gradually lengthen the midface, which is a therapeutic intervention, not a diagnostic one.
No
The device description explicitly details physical components such as an external headframe, central adjustment mechanism, rods, crosspieces, and footplates, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical device used for bone distraction in craniofacial and orthognathic surgery. This involves direct intervention on the patient's body.
- Device Description: The device description details an external mechanical device with components like a headframe, adjustment mechanisms, rods, and screws. This is consistent with a surgical implant/device, not a diagnostic test performed on biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's condition based on laboratory testing.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.
