Indications for Use
The Med4 Elite™ combines cold, heat, contrast and compression therapies. It is intended to treat post-surgical and acute injuries to reduce edema, swelling and pain for which cold and compression are indicated. It is intended to treat post traumatic and/or surgical medical and/or surgical conditions for which localized thermal therapy (hot or cold or contrast) are indicated. It is intended to be used by, or on the order of, licensed healthcare professionals in rehabilitation facilities, outpatient clinics, and athletic training settings.
Device Story
Med4 Elite is an AC-powered, software-controlled multimodality device for clinical use (rehabilitation, outpatient, athletic training) by healthcare professionals. It delivers iceless cold, heat, contrast (alternating), and intermittent pneumatic compression therapies to one or two patients simultaneously. The system uses water-circulating ergonomic wraps (ATX Series Heat Exchanger) applied to specific body parts. The unit features two separate reservoirs (hot/cold), vapor compression for cooling, and resistance heaters for warming. A touch-screen interface allows clinicians to manage therapy modalities, treatment times, temperatures, and compression settings. By providing localized thermal and compression therapy, the device aims to reduce edema, swelling, and pain, facilitating patient recovery. The device is non-sterile and intended for use over intact skin or sterile dressings.
Clinical Evidence
Clinical study on healthy volunteers measured skin temperature extremes. Results: maximum skin temperature reached 111°F (44°C) at maximum heat setting; minimum skin temperature reached 44°F (7°C) at minimum cold setting. Data supports safety and effectiveness.
Technological Characteristics
AC-powered, software-controlled unit with vapor compression cooling and resistance heating. Materials: plastic and sheet metal enclosure; wraps use nylon/denier. Connectivity: touch-screen interface. Standards: ANSI/AAMI ES60601-1:2005/(R)2012, CAN/CSA C22.2 No. 60601-1:2014, IEC 60601. Biocompatibility per ISO 10993-1, -5, -10.
Indications for Use
Indicated for patients with post-surgical or acute injuries requiring edema, swelling, or pain reduction via cold and compression, or those with post-traumatic/surgical conditions requiring localized thermal therapy (hot, cold, or contrast).
Regulatory Classification
Identification

# Product Description:
The Med4 Elite™ (Model Number 650550) is an AC powered, software-controlled multimodality device, designed to be used in a clinical setting, and under the direction and supervision of a licensed healthcare professional in rehabilitation facilities, outpatient clinics and athletic training settings. The device features iceless cold therapy, heat therapy, contrast (alternating heat and cold) therapy, and intermittent pneumatic compression therapy for one or two patients at a time. The device is designed to be compatible with the pre-existing portfolio of ergonomic Game Ready Wraps made for specific body parts (e.g., shoulder, elbow, knee, ankle, back, etc.). The Wraps are flexible water circulating garments that apply to the body to deliver cold, heat, or rapid contrast temperature and/or compression therapy. The wrap is comprised of an inner ATX Series Heat Exchanger and an Outer Sleeve.
The Med4 Elite™ allows for treatment of one or two patients, or two anatomical locations simultaneously. The device is controlled by an intuitive touch screen computer interface, allowing the user to manage the therapy modalities as well as easily adjust and monitor treatment times, temperature and compression settings.
The physical description of the Med4 Elite™ is a compact unit with four caster wheels and a built-in handle. It has two separate, covered reservoirs - one for holding cold water and the other for holding hot water. The water reservoirs, pumps, cold engine, valves, power supplies and any other electronics are inside a covered enclosure made out of both plastic and sheet metal that can only be accessed with a tool.
# Indications for Use
The Med4 Elite™ combines cold, heat, contrast, and compression therapies. It is intended to treat post surgical and acute injuries to reduce edema, swelling, and pain for which cold and compression are indicated. It is intended to treat post traumatic and post-surgical medical and/or surgical conditions for which localized thermal therapy (hot or cold or contrast) are indicated. It is intended to be used by, or on the order of, licensed health care professionals in rehabilitation facilities, outpatient clinics, and athletic training settings.

### Substantial Equivalence
None of the performance or technological differences between the Med4 Elite™ and its predicates raises any new issues of safety and effectiveness.
# Performance Testing
The Med4 Elite™ System has been subjected to design verification and validation testing for electrical safety, electromagnetic compatibility, software V&V, system/bench testing, clinical testing, and storage and transport performance. These tests verified and validated the proper operation of the system. All patient contacting components and accessories have been tested to demonstrate appropriate biocompatibility. No part of the system components or accessories are provided sterile or can be sterilized. Cleaning and disinfection instructions have been validated and are included in the labeling for the system and accessories. The Med4 Elite™ device has been found to be adequately safe and effective for the intended users. its intended uses, and use environments. The labeling materials have been found to be easy to use and understandable to the intended users.
# Sterilization/Shelf Life/Cleaning &Disinfection
The Game Ready Med4 Elite™ components (Control Unit, connector hoses, drain hoses) are provided non- sterile and do not need and cannot be sterilized. These components are not patient contacting. They are only contacted by the health care professional for setting up therapy. The unit is not intended for use in a sterile environment. Cleaning and disinfection instructions for the non-patient contacting components are given in the User Manual. The impact of repeated use of these cleaning/disinfecting materials over the expected life of the Med4 Elite™ Control Unit has been validated.
The Game Ready Med4 Elite™ device uses the previously 510(k) cleared Wraps that also work with the Game Ready GR 2.1 or new Wraps cleared in this submission. The Wraps which provide the patient contact are intended for use over intact skin or sterile dressings only. They are provided non-sterile and not intended to be user sterilized. The Wraps can be cleaned with mild detergent or antibacterial soap and cold water between uses.
Neither the Med4 Elite™ device components nor the Wraps have a definitive shelf life based on packaging. Expected life is based on frequency of use and continued functional performance.
# Biocompatibility
The Game Ready Med4 Elite Control Unit is not patient contacting. Only the wraps and the outside of the connector hoses are patient contacting. The accessories with patient contact are all surface devices with either intact skin contact or over sterile dressings. The duration of the patient contact is considered either limited (≤ 24 hours) or prolonged (>24 hrs to 30 days due to repeated treatments).
All of the wraps and the outside of the connector hoses have been tested for cytotoxicity, skin irritation and skin sensitization according to ISO 10993-1, -5 and -10 and found to be biocompatible for this patient contact and duration.
### Software
The software in the Game Ready Med4 Elite System including both custom-developed and OTS software has been validated and demonstrated to be safe and effective for its
{13}------------------------------------------------
intended use. The software is a Moderate Level of Concern as per FDA guidance. All required items related to software as required by FDA guidance have been included in this submission.
