AI/ML (Artificial Intelligence / Machine Learning)

No
The summary describes a standard electrical stimulation device and does not mention any AI or ML capabilities.

Therapeutic

No
The device explicitly states it is "not intended to be used in conjunction with therapy or treatment of medical diseases or medical conditions of any kind" and is "not designed for use on injured or ailing muscles," indicating it is not a therapeutic device.

Diagnostic

No

The device is intended for muscle stimulation to improve or facilitate muscle performance, described as a "technique of muscle training," and not for diagnosing medical conditions.

SaMD (Software as a Medical Device)

No

The device description explicitly states that the device "generates electrical impulses" and transmits them "through the system electrodes," indicating the presence of hardware components beyond just software.

IVD (In Vitro Diagnostic)

Based on the provided information, the Neux NXPRO Neuromuscular Electrical Stimulation Device is not an IVD (In Vitro Diagnostic) device.

Here's why:

IVD devices are used to examine specimens derived from the human body. The provided text clearly states that the Neux NXPRO is intended for the stimulation of healthy muscles and is applied externally to the body. It does not involve the analysis of blood, urine, tissue, or any other bodily fluid or substance.
The intended use is for muscle performance improvement. The primary purpose described is to improve or facilitate muscle performance through electrical stimulation, which is a physical intervention, not a diagnostic test.
The device description focuses on electrical impulses and muscle response. The description details how the device generates electrical impulses to stimulate motor neurons and cause muscle contractions. This is a description of a therapeutic or training device, not a diagnostic one.

In summary, the Neux NXPRO is a device that interacts with the body externally to influence muscle function, which is characteristic of a physical therapy or training device, not an in vitro diagnostic device.

Overview

Intended Use / Indications for Use

The Neux NXPRO Neuromuscular Electrical Stimulation Device is intended for the stimulation of healthy muscles in order to improve or facilitate muscle performance.

The Neux NXPRO is not intended to be used in conjunction with therapy or treatment of medical diseases or medical conditions of any kind. The NeuX NXPRO is not designed for use on injured or ailing muscles and its use on such muscles is contraindicated.

The NeuX NXPRO's electrical impulses allow triggering action potential on motor nerves (excitations). These excitations of motor neurons are transmitted to the motor endplate where they generate mechanical muscle fiber responses that correspond to muscle work. Depending on the parameters of the electrical impulses (pulse frequency, duration of contraction, duration of rest, & total session duration), different types of muscle work can be imposed on the stimulated muscles.

The various types of muscle work that the NeuX NXPRPO can impose on the stimulated muscles are able to improve or facilitate muscle performance. The NeuX NXPRO is considered a technique of muscle training.

Principles of Operation

The principle of electrostimulation is to stimulate nerve fibers by means of electrical impulses transmitted by electrodes. Neuromuscular Electrical Stimulation (NMES) is applied to the muscles and specifically targets the motor nerve with electrical pulses that can activate the junction between the nerves and muscles being treated and produce a contraction of the muscle fibers. A stimulation-induced contraction can give an effective workout for the muscle. The electrical pulses generated by the NXPRO stimulator are high quality pulses - offering safety, 510(k) Summary (NeuX – NXPRO Device)
