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 textile suit with integrated electrode pads, a battery-powered Impulse Pack, and a Windows 10-based Training Station. The system is operated by a trained professional in a clinical or training setting. The operator configures training parameters via the Training Station, which communicates wirelessly (Bluetooth LE 4.0) with the Impulse Pack. The Impulse Pack delivers localized electrical muscle stimulation (EMS) impulses to major muscle groups through the suit's electrodes. The operator monitors and adjusts channel intensities using rotary encoders. The device is intended to improve muscle performance in healthy users; it does not target medical conditions. The system includes safety features like an automatic overload trip and physical shutoff buttons.

Clinical Evidence

Bench testing only. Evidence includes biocompatibility testing (ISO 10993-5/10), electrical safety and EMC testing (IEC 60601-1, IEC 60601-2-10, IEC 60601-1-2), battery safety (IEC 62133), and software verification/validation. Engineering bench testing confirmed output waveforms under various loads (500 Ω, 2 kΩ, 10 kΩ) per FDA guidance.

Technological Characteristics

Powered muscle stimulator; 10 channels; symmetrical biphasic rectangular waveform; 85Hz frequency; 175µs pulse width. Components: textile suit with SNAP connectors, Impulse Pack (Li-Po battery, 3.8V, 2050mAh), and Windows 10 Training Station. Connectivity: Bluetooth LE 4.0. Complies with IEC 60601-1, IEC 60601-2-10, and IEC 60601-1-2. Sterilization: N/A (textile base layer).

Indications for Use

Indicated for healthy individuals to improve or facilitate muscle performance. Contraindicated for use on injured or ailing muscles or in conjunction with therapy/treatment of medical conditions.

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.

The following table outlines the essential differences with justifications for how the differences do not adversely impact the safety and effectiveness of the subject device. | Difference | Additional Details | |-------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | The Katalyst Mark 1 has only 1 operation mode compared to many modes of the predicate devices | In order to provide a consistent and predictable training experience, the Katalyst Mark 1 only provide a single mode of operation. | | Katalyst Mark 1's use of wireless communication between the controller device and the impulse generator. | In order to better utilize modern interfaces alongside with strong and robust platforms. Katalyst utilizes a Bluetooth Smart connection between its interface controller and the Impulse Pack. This is similar to the PowerDot Pd-01 Muscle Stimulator (with PowerDot Mobile Application) (K150078) | | Patient Override Control | The Katalyst Mark 1 is always operated by an Katalyst operator for a patient, and as such the operator can immediately turn off the device. | | Automatic No-Load Trip | The Katalyst Mark 1 is always operated by an Katalyst operator for a patient. The Operator's Guide outlines proper no load procedures. | Table 014- 4 Justification of differences with predicate devices # 10.Non-Clinical Tests The following non-clinical testing was provided in this 510(k): # 10.1. Biocompatibility Testing Skin contacting Katalyst Suit Base Layers have been tested to ISO 10993-10:2009 and ISO 10993-5:2009 standard under GLP. {16}------------------------------------------------ # 10.2. 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. ### 10.3. 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 IEC/EN 60601-1-2:2014 "Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic Disturbances. Edition 4.0 #### 10.4. Battery Testing The Lithium-Polymer battery used in the Impulse Pack was tested by the battery manufacturer for compliance with IEC 62133 Edition 2.0. #### 10.5. Engineering Bench Testing In addition to the full system validation testing, the 510(k) 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. Also, several 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. #### 11.Conclusion Test results demonstrate the Katalyst Mark 1 Muscle Stimulation System is substantially equivalent to the predicate devices.
