The summary describes a mechanical device for bone distraction and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
This device is a therapeutic device because its intended use is for bone stabilization and lengthening, and it is designed to correct congenital or post-traumatic defects in the mandible, which are all therapeutic actions.
No
The device is a surgical implant designed for bone stabilization and lengthening, not for diagnosing medical conditions. It performs a therapeutic function by gradually distracting bone segments.
No
The device description clearly outlines physical components like a distractor with integrated footplates, activation rod, and deactivation instrument, indicating it is a hardware device.
Based on the provided information, the Stryker Pediatric Mandibular Distractor 2 is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is for "bone stabilization and lengthening of the mandibular body and ramus" to correct defects. This is a surgical procedure performed directly on the patient's body.
- Device Description: The device is a mechanical system designed to be implanted and physically manipulate bone segments.
- Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, or tissue) outside the body to provide information for diagnosis, monitoring, or screening. This device does not interact with biological specimens in this way.
The device is clearly a surgical implant used for a therapeutic purpose within the patient's body, which falls outside the definition of an In Vitro Diagnostic device.
