The summary describes a peripheral nerve stimulator and does not mention any AI or ML components or functionalities.
No
The device is used for localization and verification of needle placement for perineural application of pharmacological agents, which is a diagnostic or procedural aid rather than a direct therapeutic intervention.
No
The device description states its intended use is for localization and verification of needle placement for perineural application of pharmacological agents, which is a procedural guidance function, not a diagnostic one.
No
The device description explicitly lists hardware components such as a stimulator, battery, Bluetooth, and charging station, indicating it is not software-only.
Based on the provided information, the NeuroMetrix ASCEND device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- ASCEND's Function: The description clearly states that ASCEND is a peripheral nerve stimulator used for localization and verification of needle placement for perineural application of pharmacological agents. This is an in vivo procedure, meaning it's performed directly on a living patient, not on a specimen outside the body.
Therefore, ASCEND falls under the category of a therapeutic or procedural medical device, not an IVD.

Device Description
ASCEND is a battery powered peripheral nerve stimulator. This device is intended for localization and verification of needle placement for perineural application of pharmacological agents.
ASCEND consists of the following components:
5.1 Stimulator
The Stimulator contains the electronic circuitry and software required to electrically stimulate the peripheral nerve. It also contains other functionality such as the user interface.
5.2 Battery
The Stimulator is powered from a high capacity re-chargeable Li-polymer battery. The battery has a nominal voltage of 3.7 V DC and a maximum operating voltage range of 2.75 V to 4.2 V. Its rated capacity is 2140 mAh minimum, 2200 mAh typical. The battery has a built-in safety circuit. The battery is UL recognized.
5.3 Bluetooth
The Stimulator is equipped with a Bluetooth wireless module that provides serial communication between it and other devices.
The Bluetooth module is a Class 1 device that meets the Bluetooth v. 1.2 specifications utilizing the ISM frequency of 2.4 GHz with a variable output power maximum of 12 dBm. The module complies with FCC and CE Marking requirements.
5.4 Charging Station
The Charging Station is used to re-charge the Stimulator's Li-polymer battery.
