Intended Use

The Katalyst Mark 1 is intended to stimulate healthy muscles in order to improve or facilitate muscle performance. It 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 Mark 1 is Rx only.

Device Story

Katalyst Mark 1 is a powered muscle stimulation system consisting of a compression textile suit with embedded electrodes, a battery-powered Impulse Pack, and a tablet-based control application. The system is operated by a certified professional in a clinic or training environment. The operator configures training programs via the Katalyst Application on a Windows 10 tablet, which communicates wirelessly via Bluetooth Smart to the Impulse Pack. The Impulse Pack delivers regulated electrical impulses to major muscle groups through the suit's electrodes. The device provides localized EMS to improve muscle performance. The operator monitors training duration and intensity levels through the tablet interface. The system includes safety features like automatic overload/no-load trips and a physical emergency shutoff button. The device is intended for healthy muscles only; it is not for rehabilitation or medical treatment.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included biocompatibility (ISO 10993-5/10), electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), nerve/muscle stimulator performance (IEC 60601-2-10), and battery safety (IEC 62133). Engineering bench testing included oscilloscope waveform verification under various loads and wireless risk mitigation validation.

Technological Characteristics

System comprises a compression suit with embedded electrodes, Impulse Pack, and tablet controller. Uses bipolar square waveforms. Powered by 3.8V Li-Po battery. Connectivity via Bluetooth Smart (BT LE 4.0). Complies with IEC 60601-1, IEC 60601-2-10, and IEC 60601-1-2. Electrodes use 4mm standard SNAP connectors. Software-controlled intensity and training parameters.

Indications for Use

Indicated for healthy individuals 18+ years of age to stimulate muscles to improve or facilitate muscle performance. Contraindicated for individuals with cardiac pacemakers, known heart conditions, history of cardiac arrhythmia, pregnancy, implanted defibrillators, or other implanted metallic/electronic devices.

Regulatory Classification

Identification

A powered muscle stimulator is an electrically powered device intended for medical purposes that repeatedly contracts muscles by passing electrical currents through electrodes contacting the affected body area.

Katalyst utilizes a Bluetooth Smart connection between its interface controller and the impulse pack. | System validation testing scenarios covering mitigation of wireless risks in accordance with FDA's “Radio Frequency Wireless Technology in Medical Devices - Guidance for Industry and Food and Drug Administration Staff” were added to our full system testing protocol to ensure safe and effective use In addition, this is similar to the PowerDot Pd-01 Muscle Stimulator (with PowerDot Mobile Application) (K150078) | | Using a tablet / touch interface to control channel impulse intensities. | The touch application is used to control the impulse intensities wirelessly via Bluetooth. | Impulse Pack firmware and Katalyst Application software documentation, consistent with a Moderate level of concern, is provided with this 510(k). System Validation Testing proves that all software requirement specifications were met and all software hazards were mitigated to Accepted risk level In addition, this is similar to the PowerDot Pd-01 Muscle Stimulator (with PowerDot Mobile Application) (K150078) | | The Katalyst Mark 1 has a current density (RMS) greater than 2mA/cm² | As outlined in IEC 60601-2-10 additional warnings and guidance are included in the Operator's Guide to properly advice operators on proper procedures to increase to intensities. | The Katalyst Mark 1 has been tested and conformed to the IEC 60601-2-10:2012 "Medical electrical equipment - Part 2-10: Particular requirements for the basic safety and essential performance of nerve and muscle stimulators." Edition 2.0 standard. Furthermore, the subject device has complied with the recommendations set forth in FDA's "Guidance Document for Powered Muscle Stimulator 510(k)s" | | | issued on June 9, 1999 In addition, Compex Sport (K011880) has a current density of 3.84mA/cm² which includes similar warnings and guidance. | | {16}------------------------------------------------ {17}------------------------------------------------ #### 1.11 Non-Clinical Tests The following non-clinical testing was provided in this 510(k): #### Biocompatibility Testing Skin contacting electrodes pads have been tested to ISO 10993-10:2009 and ISO 10993-5:2009 standard under GLP. #### Software Verification and Validation Impulse Pack firmware and Katalyst Application software documentation, consistent with a Moderate level of concern, is provided with this 510(k). System Validation Testing proves that all software requirement specifications were met and all software hazards were mitigated to Accepted risk level. #### Electrical Safety and Electromagnetic Compatibility Testing The Katalyst Suit and the Impulse Pack have been designed to comply and tested for compatibility with the applicable clauses of the following FDA-recognized standards: - . IEC/EN 60601-1:2005 "Medical Electrical Equipment - Part 1: General Requirements for Safety" Edition 3.1 - . IEC 60601-2-10:2012 "Medical electrical equipment - Part 2-10: Particular requirements for the basic safety and essential performance of nerve and muscle stimulators." Edition 2.0 - .
