• Applicant: Actegy , Ltd.
• Product Code: IPF · Physical Medicine
• Decision Date: Jun 28, 2013
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 890.5850
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Revitive IX is indicated for: - Relaxation of muscle spasms; . - Prevention or retardation of disuse atrophy; ● - Increasing local blood circulation; . - Muscle re-education; . - Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis; and . - Maintaining or increasing range of motion. .

Device Story

Revitive IX is a powered muscle stimulator (NMES) used to deliver electrical stimulation to muscles via foot pads or electrode pads. It features an optional 'IsoRocker' for ankle movement during stimulation. The device is operated by the user via a remote control and interface. It transforms electrical input into biphasic pulses (20-80Hz) to induce muscle contractions. Used in home or clinical settings, it helps patients by increasing local blood circulation, preventing disuse atrophy, and aiding muscle re-education. The healthcare provider or user monitors stimulation levels (0-150V) via the display. The device includes an automatic shut-off and patient override control for safety.

Clinical Evidence

Bench testing only. Biocompatibility, electromagnetic compatibility, and safety testing were conducted. Results confirmed the device functioned as intended and met expected performance standards.

Technological Characteristics

Powered muscle stimulator (21 CFR 890.5850). Materials: ABS casing, NBR footpads. Energy: 100-240V AC power adaptor. Output: Biphasic pulses, 20-80Hz, regulated voltage up to 150V. Two output channels (sole and body pads). Features: IsoRocker for ankle movement, remote control, user interface. Connectivity: Standalone. Standards: EN60601-1-2:2007, 21 CFR 898.

Indications for Use

Indicated for patients requiring muscle spasm relaxation, prevention of disuse atrophy, increased local blood circulation, muscle re-education, post-surgical calf muscle stimulation to prevent venous thrombosis, or maintenance/increase of range of motion.

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.

Predicate Devices

• IF 3Wave Interferential Stimulator System, Model 711 OS (K050046)
• Lifecare Garment Electrodes (K103719)

#### Intended Use / Indications for Use

The Revitive IX is indicated for:

- Relaxation of muscle spasms; .
- Prevention or retardation of disuse atrophy; ●
- Increasing local blood circulation; .
- Muscle re-education; .
- Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis; and .
- Maintaining or increasing range of motion. .

# Technological Characteristics

The Revitive IX consists of foot pads and/or electrode pads that deliver electrical stimulation to the muscles; an optional feature that allows for ankle movement during stimulation (IsoRocker); a remote control; and a user interface. See the table below for a technological comparison with the predicate IF 3Wave.

Both Revitive IX and Compex IF 3Wave are mid-frequency (20-80Hz) muscle stimulator devices with biphasic pulses, and both operate in a range which balances between comfort and effective contractions. While there are minor differences in the values for certain of the technological features, the key parameters of the Revitive IX and Compex IF 3Wave are within the same range.

## Performance Data

Biocompatibility and electromagnetic compatibility and safety testing, and other performance testing were conducted. In all instances, the Revitive IX functioned as intended and the results observed were as expected.

#### Substantial Equivalence

The Revitive IX is as safe and effective as the IF 3Wave Interferential Stimulator System and the Lifecare Garment Electrodes. The Revitive IX has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate devices. The minor technological differences between the Revitive IX and its predicate devices raise no new issues of safety or effectiveness. Performance data demonstrate that the Revitive IX is as safe and effective as the predicate devices. Thus, the Revitive IX is substantially equivalent.
