Device. | Staodyn EMS +2 | ## Description of the device. The MediStim PLUS is a portable two-channel battery operated neuromuscular electrical stimulator. The device is intended for prescriptive use per 21 CFR 801,109. It comprises of the device and two colour differentiated lead wires. which connect to four skin surface electrodes. The device is powered by a 9-volt (type 6/22) battery located in a compartment to the rear of the device with a detachable batterv cover. The device is supplied with a set of adhesive electrodes, a carrying case, the user instruction manual and a battery. Built in safety features are clearly outlined in this submission, which greatly reduce the possibility of mis-use. Page 1 of 2 SKI {1}------------------------------------------------ ## Intended use. The MediStim PLUS is intended for use with a wide range of patients, some of who may have limited dexterity. It is intended to use the principles of neuromuscular electrical nerve stimulation through skin contact surface electrodes for the purpose of activation of weak and atrophied muscles or the inhibition of overactive muscle. 「echnological comparison. The MediStim PLUS is similar to the EMS+2 in that it delivers a stimulation signal. which is almost identical with similar parameter settings. The MediStim PLUS has an LCD screen with user compliance monitoring, where as the EMS+2 does not have this feature. Non-clinical tests. The MediStim PLUS was designed to. and has been independently tested to IEC 601-1: 1998 +A1: 1991+ A2: 1995, IEC 601-2-10:1987. IEC 601-1-2:1993. Bio-Medical Research LTD adheres to recognised and established industry practices and all devices are subject to final performance testing. A Hazard analysis, risk analysis and failure mode effects analysis have been carried out for the device. {2}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
