Drug, and Cosmetic Act (that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrb/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

DEVICE DESCRIPTION The device is intended to be used as a 24-month reusable patient return electrode for patients age 12 years and older. The Universal (model 0845) and Universal Plus (model 0847) have a single cord that connects to one generator. The Universal Dual (model 0846) and Universal Plus Dual (model 0848) have two cords that can connect to one or two generators. The Mega Soft Universal Patient Return Electrodes (ie. Mega Soft) are constructed of a layer of conductive material strain-relieved between an insulative polymer gel, and sealed between two layers of a thermal polyurethane plastic film. The thermal polyurethane plastic film and the contained polymer gel enveloping the conductive material is compressable but does not laterally move under pressure. The polymer acts as a dielectric protection and is encapsulated by a layer of urethane film. The dielectric protection remains between the thermal polyurethane plastic film and the conductive layer irrespective of pressure. A two-conductor cable connects the conductive layer of the device to a two-conductor DetachaCable™. The DetachaCable is connected to a standard monopolar ESU. The DetachaCable is available in a variety of configurations and lengths, designed to be compatible with the various compatible generators available on the market and was cleared under K080741 on 16 December 2008. #### VI. INDICATIONS FOR USE This device is designed to be used whenever monopolar electrosurgery is indicated. The intended use of this device is to conduct monopolar electrosurgical energy from target tissue of a patient back to one or two electrosurgical units (ESU), or generators. Electrosurgical use is restricted to use with isolated monopolar electrosurgical generators. The device is not intended for RF ablation. {6}------------------------------------------------ ### VII. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE # Technological Characteristics The Megadyne Mega Soft Patient Return Electrodes (subject devices) have the identical technological characteristics as the predicate device Mega Soft Universal Patient Return Electrode. Both the subject and predicate devices are intended to pass current from the active electrode through the patient's body to the patient return electrode and back to the generator to complete the circuit. Similarities with the subject devices compared to the predicate devices cleared under K133726 are listed below. - Indications ● - Materials ● - Operational principles - Packaging ● - Shelf-Life The following differences exist between the subject and predicate device, (dependent upon model): - Intended population ● - Pad thickness - Dual cord (model 0846 and 0848) ● - Model number/tradename ### VIII. PERFORMANCE DATA ### Bench Performance Bench performance testing was conducted to demonstrate equivalency of the subject devices to the predicate devices. The following parameters were evaluated: - Electrical resistance - Wear and use - Cleaning and handling ● - Compliance with IEC 60601-1, IEC 60601-1-2 - Compliance with IEC 60601-2-2 # Animal Testing Acute animal studies were conducted that evaluated the performance of the Mega Soft Universal Patient Return Electrode in simulated surgical procedures. - Compliance with IEC 60601-2-2 5th Ed - Pad orientation {7}------------------------------------------------ ### IX. CONCLUSION The testing criteria demonstrates that the following subject devices perform and are substantially equivalent to the predicate device, Mega Soft Universal Patient Return Electrode (K133726, model 0845). - Megadyne Mega Soft Patient Return Electrode Universal (model 0845) ● - . Megadyne Mega Soft Patient Return Electrode Universal Dual (model 0846) - Megadyne Mega Soft Patient Return Electrode Universal Plus (model 0847) . - . Megadyne Mega Soft Patient Return Electrode Universal Plus Dual (model 0848) The design requirements raise no new questions of safety and effectiveness.
