It has no electronics built in and is mainly made out of textiles, plastics and aluminum.

More Information

No
The summary describes a standard electrical muscle stimulation (EMS) device with various components and connectivity options. There is no mention of AI, ML, or any adaptive or learning algorithms used in the device's operation or program selection. The programs are pre-defined and parameters are adjusted by the trainer.

Yes
The device is intended to treat specific medical conditions, such as re-educating muscles, relaxation of muscle spasm, and retarding or preventing disuse muscle atrophy.

No

This device is intended to stimulate muscles for improvement or rehabilitation and does not perform any diagnostic functions like detecting, measuring, or analyzing physiological parameters to identify a medical condition.

No

The device description explicitly details hardware components including a control unit, electrode vest, straps, belt, and a wireless stimulation device ("i-body connect wireless") which contains a stimulation circuit board. While software is mentioned for control and updates, the device is fundamentally a hardware-based electrical muscle stimulator.

Based on the provided text, the miha bodytec II device is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • miha bodytec II Function: The description clearly states that the miha bodytec II is a transcutaneous electrical muscle stimulation (EMS) device. It works by applying electrical impulses to the skin to stimulate muscles.
  • Intended Use: The intended use is for muscle stimulation to improve performance, re-educate muscles, relax muscle spasms, and prevent disuse muscle atrophy. These are all related to the direct stimulation of the body, not the analysis of specimens taken from the body.
  • Device Description: The description focuses on the hardware components (control unit, electrodes, vest, straps, belt) and how they deliver electrical stimulation. There is no mention of collecting or analyzing biological samples.

Therefore, the miha bodytec II falls under the category of a physical therapy or rehabilitation device, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Electrical Safety and Electromagnetic Compatibility testing: miha bodytec II was tested according to and is in compliance with recognized standards for electrical safety and electromagnetic compatibility.

Software and System validation: The miha bodytec II comprises firmware which was verified and validated according to IEC 62304 and FDA's guidance: General Principles of Software Validation. Software validation demonstrated that the firmware met the software system requirements. The full system validation testing also included testing in accordance with the recommendations of FDA's "Guidance Document for Powered Muscle Stimulator 510(k)s" issued on June 9, 1999. Oscilloscope tracings were obtained of the device output waveforms under maximum supported voltage and pulse widths under loads of 500 Ω, 2 kΩ and 10 kΩ. Additional System-level tests were conducted, including electrical tests of the interfaces, thermographic inspections, tests in climate chamber, shock and vibration tests.

Usability validation: The overall system was validated to confirm that the device meets its intended use, i.e. can be used safe and effectively by the specified users within the specified use environment, taking into account human factors and usability requirements.

Bench testing of the electrodes was performed to demonstrate uniform current distributions (dispersion testing). The test case was built up according to FDA's requirements.

4 batches of electrodes were tested. From each batch 8 lateral back-electrodes, 1 upper back-electrode and 1 abdomen-electrode were selected. The electrodes were cut out of the vest and moistened to be covered by the undergarments. 8 measure points from each chest-electrode, each lateral back-electrode and each upper back-electrode as well as 5 measure points from each abdomenelectrode were defined. As indicated by FDA the electrodes were measured prior to and after cleansing. After this measuring period the accelerated aging was applied and followed by another measuring period which was conducted exactly the same like the first one. All tests successfully passed. To calculate the shelf life, we establish new testing according to ASTM F1980-16. In a climate cabinet an accelerating aging condition for the electrodes was simulated at 60°C for 10 weeks. Through testing the electrical resistance of the electrodes, a 3-year storage was tested. Altogether 10 electrodes and 6 contact points were tested. All tests were successfully passed.

    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 Katalyst Training
    System is an Over-The-
    Counter device intended
    to stimulate healthy
    muscles in order to
    improve or facilitate
    muscle performance. It
    is to be used by adults
    only.
    The Katalyst Training
    System is not intended
    to be used in
    conjunction with therapy
    or treatment of medical
    diseases or medical
    conditions of any kind.
    None of the training
    programs or operational
    parameters are
    designed to target
    injured or ailing muscles
    and its use on such
    muscles is
    contraindicated. The
    Katalyst Training
    System's electrical
    impulses allow the
    triggering of action
    potentials on
    motoneurons of motor
    nerves (excitations).
    These excitations of
    motoneurons are
    transmitted to the
    muscle fibers via 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. | Similar between
