The Liberty Medical Solutions, LLC Multi-Mode Stimulator (MMS) (the Device) is a battery powered electrotherapy device intended for clinic and outpatient rehabilitative therapy, acute postoperative care and home use for patients suffering from a variety of chronic pain issues. Prescribed by a physician, it gives the clinician a variety of electrotherapy modes to treat a range of indications. The MMS is designed for clinician and patient ease of use and provides safe and effective dispensing of the desired electrotherapy treatment. The Intended Use Environment is Home Healthcare but the Device can also be used in a Chiropractic, Physical Therapy or Pain Management Clinic. The Device uses a tactile button user interface for control of the operating system and therapy amplitude settings. The Device has a liquid crystal character display which provides information to the user and displays the current therapy settings. The Device’s therapeutic output is transmitted through the patient lead wires to the cutaneous hydrogel electrodes affixed to the user’s skin. The energy generated by the Device is conveyed, via the patient lead wires and cutaneous electrodes, through the patients skin to excite either the underlying motor nerves to elicit involuntary muscle contractions or the sensory nerves to manage pain.
