No
The summary describes a passive electrical stimulation probe and dilators, with no mention of data processing, analysis, or any computational capabilities that would suggest AI/ML. The performance studies focus on electrical safety, material compliance, and sterilization, not algorithmic performance.
No
The device is used to assist in locating nerves during surgery by delivering electrical stimulus, which is a diagnostic/monitoring function rather than a therapeutic one.
Yes
The device is indicated for use during surgery of the spine to deliver an electrical stimulus to tissues and nerves to assist in "locating those nerves at risk during the surgical procedure," which implies identifying or diagnosing the location of nerves.
No
The device description explicitly details physical components made of stainless steel, polytetrafluoroethylene, and polyphenylsulfone, which are hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to deliver electrical stimulation during surgery to assist in locating nerves. This is an in vivo (within a living organism) application, not an in vitro (outside of a living organism) diagnostic test performed on samples like blood or tissue.
- Device Description: The device is described as an instrument used to deliver electrical stimulation to tissue. This aligns with a surgical tool, not a diagnostic device that analyzes biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information based on laboratory tests.
Therefore, the AVS® ARIA Neuromonitoring Probe and AVS® ARIA Probe Dilators are surgical instruments used for neuromonitoring during spine surgery, not an in vitro diagnostic device.

Device Description
The AVSA® ARIA Neuromonitoring Probe (NM Probe) and AVSA® ARIA Probe Dilators are used as instruments to deliver electrical stimulation to tissue during intraoperative neurological monitoring. The NM Probe and probe dilators are available in monopolar configuration. These are made from stainless steel (NM Probe) insulated with either polytetrafluoroethylene or polyphenylsulfone (dilator tubes). The NM probe has a male 1.5mm DIN connector. The components are provided clean to users for sterilization prior to use. The components are not intended for cleaning, reprocessing, or reuse.
The NM Probe and probe dilators are provided by Stryker Spine non-sterily and must be sterilized by the end user prior to use and subsequently disposed of after use in a single case. These devices are not labeled non-pyrogenic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The device was tested in accordance with IEC 60601-1-2: 2007 and the test results indicate that the AVSA® ARIA Neuromonitoring Probe and AVSA® ARIA Probe Dilators are substantially equivalent to predicate devices. All stainless steel components, comply with ASTM F899 and all PTFE components comply with ASTM D4895. All devices have been validated, in both gravity and pre-vacuum, in their surgical case set for a Sterility Assurance Level (SAL) of 10-6 according to AAM ST 79: 2010, AAMI A1:2010, AAMI TIR 12:2010, and ISO 17665-1: 2006. The steam sterilization parameters are:
Prevacuum (Porous Load) steam sterilization autoclave:
- Temperature: 132°C (270°F) .
- Exposure Time: 4 Minutes
- Dry Time: 20 Minutes .
Gravity Displacement steam sterilization autoclave:
- Temperature: 132°C (270°F) .
- Exposure Time: 15 Minutes
- Dry time: 30min. .
