Device Description Disposable EEG Electrodes includes three models: DL, E-CAP, FLEX-CAP. {4}------------------------------------------------ The models E-CAP and FLEX-CAP are EEG electrode positioning systems used to place a number of EEG electrodes in a uniform and consistent manner on the head in order to transmit electrophysiological signals from an individual to data collection devices. The model E-CAP is made from spandex type material with silver/silver chloride-plated ABS electrodes in silicone base attached to the cap. The model FLEX-CAP is made from spandex type material with silver/silver chloride ink printed electrodes on PET in silicone base attached to the cap, the cap covering the entire scalp and is held in place with chin straps. The spandex type material holds the electrodes securely in position during an EEG recording. The electrodes on the caps connect to the EEG equipment either through an adapter cable or in some instances, special connector on match EEG equipment. The electrical activity of the brain is transferred via the electrolyte to the electrode and then to the EEG equipment for evaluation. The models E-CAP and FLEX-CAP have been built with the placement of 2-128 electrodes, the size of cap is from 26 to 66 cm. The model DL is a silver/silver chloride-plated ABS electrode with shrink tubing and connector, which is used on the model E-CAP. In addition, model DL can be used alone on the scalp for EEG monitoring. The electrodes on the Disposable EEG Electrodes (MODEL: DL, E-CAP, FLEX-CAP) are positioned according to the International Ten-Twenty System (10-20) of Electrode Placement. In addition, Disposable EEG Electrodes (MODEL: DL, E-CAP, FLEX-CAP) with as a few as 2 or as many as 128 electrodes, have been mounted in a place according to the 10-10 American Electroencephalographic Society positioning system. Disposable EEG Electrodes (MODEL: DL, FLEX-CAP) can also be custom-made, in which the numbers of electrodes and placement of electrodes are made under an instruction from customs. ## 5. Indication for use Disposable EEG Electrodes (MODEL: DL, E-CAP, FLEX-CAP) is intended for use in routine clinical settings where rapid placement of a number of EEG electrodes is desired. ## 6. Comparison to Predicate Device Compared to the predicate devices, the subject device has same intended use, similar product design, and same performance effectiveness as the predicate device as summarized in the following table. | Feature | Subject device | Predicate device | Discussion | |-----------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------|------------| | 510(k) Number | - | K112319 | - | | Indication for Use | Disposable EEG Electrodes (MODEL: DL, E-CAP, FLEX- CAP) is intended for use in routine clinical settings where rapid placement of a number of EEG electrodes is desired. | The Electro-Cap is intended for use in routine clinical settings where rapid placement of a number of EEG electrodes is desired. | Same | | Classifica tion | Class II per 21CFR882.1320, | Class II per 21CFR882.1320, | Same | {5}------------------------------------------------ | Regulatio n | cutaneous electrode | cutaneous electrode | | |---------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Product Code | GXY, Electrode, cutaneous | GXY, Electrode, cutaneous | Same | | Environm ent of use | Electrophysiological | Electrophysiological | Same | | Intended user | Neurologists | Neurologists | Same | | Target patient | Adults and Children | Adults and Children | Same | | Where used | On the head | On the head | Same | | Number of contacts | 2-128 | 2-256 | The placement of the electrodes is according to the International (10-20) System of Electrode Placement or (10- 10) American Electroencephalographic Society positioning system. The number of the electrodes in use is according to the needs of clinic practice. By using 19 electrodes and 32 electrodes (or 19 channels and 32 channels can meet majority needs, while using channels up to 128 can satisfy most medical applications as the predicate K112319 does. The disposable electrodes can adapt to most EEG equipment as the predicate K112319 does. Both of the subject device and the predicate device are applied to record EEG signals on patients' scalp, and the bioelectrical signals are in microvolts-level. The electrodes only transfer tiny bioelectrical signals to the EEG recording equipment. The doctors can read the signals according the channels assigned, such as 19 channels or 32 channels. The safety issue only concerns the bio- | | | | | compatibility of the electrode materials, while the effectiveness mainly concerns the electrode surface materials. The number of electrodes in the products is irrelevant to the safety and also doesn't affect the effectiveness compared to predicate devices. Therefore, the difference in numbers of electrodes does not raise any new safety risk or effectiveness issue. | | Size of Caps | Various - babies to large 26cm to 66cm | Various - babies to large 26cm to 66cm | Same | | Style of Caps | Full head cap | Full head cap | Same | | Ear Slits | Yes | Yes | Same | | Cap material | Spandex | Spandex | Same | | Electrode Mounts | Silicone | Polyethylene | The mount base used in the Disposable Electrodes is designed for fastening the electrodes on the cap fabric, and the base don't involve in the bioelectrical signal recording. Silicone is a common material used in medical device. The silicone mount base can be made soft than the base made by polyethylene in the predicate device. Therefore, by using silicone materials as the mount base offers more comfortable experience to the users. Furthermore, the silicone mount bases used in this Disposable Electrodes have passed the bio-compatibility test. Thus, the use of silicone as electrode mount base does not raise new safety and effectiveness issues. | | Cable Length | 0.1 m - 3.0 m | Various - 3 to 5 feet | The length of the cable in the Disposable electrodes is different from the predicate device but it doesn't raise new safety and effectiveness issue. Because the cable is used for transferring EEG signals (the tiny bioelectrical signal in ~ several ten microvolts peak to peak) from the patients' scalp to the data record devices. The cable is designed in conformance with AAMI / ANSI ES60601-1:2005/(R)2012 and A1:2012, C1:2009/(R)2012 and A2:2010/(R)2012 (consolidated text) Medical electrical equipment - Part 1: General requirements for basic safety and essential performance (IEC 60601- 1:2005, mod). | | Type of Cables | Standard ribbon cable and lead wires | Standard ribbon cable and lead wires | Same | | Electrode Metal | 1.
