No
The device description and performance studies focus on the physical characteristics and electrical properties of probes and dilators used for nerve stimulation, with no mention of AI or ML algorithms for data analysis, interpretation, or decision-making.
No.
The device is used for tissue dilation and stimulation for location and identification of nerves, primarily for neuromonitoring during surgery, not for treating a condition or disease.
Yes
The device is described as an "intraoperative neuromonitoring (IONM) stimulation accessory" intended for "locating and identifying peripheral nerves including spinal nerve roots during spinal surgery." This function, which involves acquiring information about the state or location of anatomical structures for clinical decision-making, falls under the definition of diagnostic use.
No
The device description clearly details physical components (probes/guidewires and dilators) with specific dimensions and materials, indicating it is a hardware device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.
- This device is used in vivo (inside the body) during surgery. Its purpose is to physically dilate tissue and to stimulate nerves within the patient's body to help the surgeon locate and identify them.
The description clearly states its intended use is for "tissue dilation and stimulation of peripheral nerves including spinal nerve roots for location and identification during spinal surgery." This is an in vivo surgical tool, not an in vitro diagnostic test.
