In this situation, the EEG electrodes are fitted to the patient by a trained clinician prior to the patient being sent home. No subsequent intervention is required by the patient. Upon completion of the recording, the data which is stored on a memory card is reviewed by a clinician using review and analysis software on a PC. lt is a compact USB amplifier which provides 32 channels with internal expansion option) with built-in calibration and electrode impedance measurement. Also provided is a Nonin pulse oximeter interface, a Patient Event input and an Aux DC input. Optional wireless communication is available (Bluetooth and WLAN WiFi). There are two variants of the Trackit T4 EEG Amplifier: - Trackit T4-32 providing 24 referential + 8 poly channels. . - . Trackit T4-68 providing 64 referential + 4 poly channels (using internal expansion board). Plug-on Patient Connection Units (PCUs) provide 32 channel touchproof inputs (model T4-PCU 24+8) or 68 channels (model T4-PCU 64+4). The Amplifier is intended to be connected to a USB port on a PC which is powered from a medically {4}------------------------------------------------ approved power supply. In addition it can be battery powered in ambulatory applications. This equipment is intended only as an adjunct device in patient assessment; it must be used in conjunction with other methods of patient diagnosis. The equipment does not sustain or support life. #### DEVICE INDICATIONS FOR USE The Trackit T4 EEG Amplifier is intended to be used as a front-end amplifier to acquire, store and transmit electrophysiological signals (wireless or cabled). #### COMPARISON OF TECHNICAL CHARACTERISTICS The following chart compares the new T4 EEG Amplifier with the company's R-40 EEG Amplifier as the predicate device.

It is based on existing, well established technologies and is intended for use in the established field of EEG. The differences between the new device and the predicate device are: - 1. The new device uses the same internal electronics as the R-40 but its case has been reduced in size to make it more suitable for ambulatory use. - 2. The Indications for Use for the new device are the same as the R-40. - 3. The new device can be powered from an external power pack for ambulatory use. - 4. The new device incorporates a small alpha-numeric display which shows battery capacity, elapsed recording time and wireless connection status during ambulatory use. - 5. The channel count has been reduced from 40 to 32 in order to reduce the size of the device to optimize it for ambulatory use. The channel count can optionally be increased to 68 with an internal expansion board, for more complex clinical examinations. - 6. The Electro-cap connector has been removed in order to reduce the size of the device to optimize it for ambulatory use. - 7. The front-panel impedance limit feature has been removed. Impedance limits can be adjusted on the host computer during set-up. - 8. The new device is suitable for ambulatory and home use. {7}------------------------------------------------ These differences raise no new questions concerning safety or effectiveness.
