Intended Use
EMS: The Compex Sport Elite 3.0 is intended to stimulate healthy muscles in order to improve or facilitate muscle performance. The work imposed on the Compex Sport Elite 3.0 programs is not suitable for relabilitation or physiotherapy. TENS: The Compex Sport Elite TENS is intended for: - Temporary relief of pain associated with sore and aching muscles due to strain from exercise or normal household and work activities: - The symptomatic relief and management of chronic, intractable pain and relief of pain associated with arthritis. The Compex Sport Elite 3.0 is an Over-the-Counter device to be used by adults only.
Device Description
The Compex Sport Elite 3.0 is an electrical stimulation device, which stimulates healthy muscles by means of electrical impulses transmitted by electrodes. The electrical pulses generated by the Compex Sport Elite 3.0 stimulates motor nerves to stimulate a muscular response. Depending on the parameters of theelectrical impulses (pulse frequency. duration of contraction, duration of rest, and totalsession duration). different types of muscle work can be imposed on the stimulated muscles. The Compex Sport Elite 3.0 may therefore be considered a technique of muscletraining. TENS (Transcutaneous Electrical Nerve Stimulation) and NMES (NeuroMuscular Electrical Stimulation) target different nerve groups of the body. TENS specifically targets the sensory nerves, which are responsible for sending pain signals to the brain. NMES targets the muscle itself, specifically through the motor nerves. This allows the NMES machine to create a muscle contraction to recruit more muscle fibers when training; warming up or recovering. The Compex Sport Elite 3.0 system consists of these components: - 1x Stimulator - 1x Lead WireSet - 2x Small Performance Snap Electrodepackages ● - 2x Large Performance Snap Electrodepackages - 1x Charging Cable ● - 1x Carrying Case ● These components are packaged together in a carrying case along with the user guide and a battery charger. The electrodes are supplied by Axelgaard Mfg. Co., Inc. and cleared under K130987. The stimulator is a microprocessor controlled 4-channel electro-stimulator. The stimulator drives each output channel independently based upon the parameters predefined for a program selected by the user operates the device through a User Interface (UI) consisting of a graphic LCD, keypad controls and supporting software. The User Interface is made up of different menus that allow the following functions: set up the device (Options Menu), select a desired category (Category Menu), select a preset program (Treatments ) Menu), tune a selected program (Stimulation Menu), andadiust the stimulation intensities (Level Menu).

No
The document describes a microprocessor-controlled electrical stimulator with predefined programs selected by the user. There is no mention of AI, ML, or any adaptive or learning capabilities.

Yes.

The device is intended for "Temporary relief of pain associated with sore and aching muscles" and "The symptomatic relief and management of chronic, intractable pain and relief of pain associated with arthritis," which are therapeutic indications.

No

The Compex Sport Elite 3.0 is intended to stimulate healthy muscles to improve performance or provide temporary pain relief, and its use is not suitable for rehabilitation or physiotherapy. It focuses on muscle stimulation (NMES) and pain relief (TENS) rather than diagnosing medical conditions.

No

The device description explicitly lists hardware components such as a stimulator, lead wire set, electrodes, charging cable, and carrying case. It is an electrical stimulation device that transmits electrical impulses via electrodes.

Based on the provided text, the Compex Sport Elite 3.0 is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
  • Compex Sport Elite 3.0 Function: The description clearly states that the Compex Sport Elite 3.0 is an electrical stimulation device that applies electrical impulses to the body through electrodes to stimulate muscles or nerves. It works externally on the body, not by analyzing samples taken from the body.
  • Intended Use: The intended use is for stimulating healthy muscles to improve performance (EMS) and for temporary pain relief (TENS). These are direct applications to the body, not diagnostic tests performed on samples.

Therefore, the Compex Sport Elite 3.0 falls under the category of an electrical stimulator for therapeutic and performance enhancement purposes, not an In Vitro Diagnostic device.
