#### Technological Characteristics:

The Intelligent Hearing Systems (IHS) family of products is intended to be used for recording and analysis of human physiological data for the purpose of diagnosis, screening, and treatment of sensory disorders and nerve monitoring.

Evoked response systems provide a means to elicit and acquire signals evoked in response to appropriate stimuli, and can be used for different kinds of tests: Auditory evoked potentials (AEP), somatosensory evoked potentials (SEP), visual evoked potentials (VEP), nerve stimulation/monitoring, cochlear promontory stimulation (transtympanic eABR), etc. These testing variations are called "modalities", and each modality has its own unique hardware/software requirements.

The feature modifications described in this 510(k) are to incorporate additional/expanded indications to the SmartEP device for SEP, VEP, and Nerve Stimulation/Monitoring to the previously FDA cleared indications for AEP testing (refer to FDA 510(k) #K904926). Specifically, additional hardware and software features have been added to the original SmartEP device system to objectively acquire somatosensory/visual evoked potentials upon the presentation of a somatosensory/visual stimulus, as well as to provide nerve stimulation and monitoring functionality.

SEP testing is performed by providing skin-surface (cutaneous) electrical stimulation to a patient's upper and lower limbs. A somatosensory stimulus (constant-current pulses, etc.) is presented to the subject's skin through the use of an SEP electrical stimulator probe which delivers the constant-current electrical stimulus through two metal prongs or skin-surface electrode connections. As in the case of AEP testing. the EEG response from the brain is recorded through the use of scalp electrodes placed on the patient, amplified/filtered, digitized, and averaged with multiple responses to obtain a final evoked response signal. SEP testing is useful to determine the integrity of the somatosensory pathways and how well the nerves that connect to the spinal cord are able to send and receive sensory information (such as pain, temperature, and touch), as well as to help diagnose the nature of any possible sensory impairment. The anatomical sites of contact for SEP testing are the patient's upper/lower limbs and head (with the contact object being two metal prongs or skin-surface electrodes connected to a constant-current stimulator probe) and the patient's scalp and possibly other body sites (with the contact object being electrodes that are capable of measuring bio-potentials).

VEP testing is performed by providing photic light stimulation to a patient's eyes. A visual stimulus (checker-board light patterns, light bars, etc.) is presented to the subject through the use of a visual stimulator light (or LED) array or monitor which delivers visual patterns covering a particular area of the field of view. As in the case of AEP testing, the EEG response from the brain is recorded through the use of scalp electrodes placed on the patient, amplified, and averaged with multiple responses to obtain a final evoked response signal. VEP testing is useful to determine the integrity of the visual pathways as well as to help diagnose the nature of any possible sensory impairment. VEP testing can help provide valuable diagnostic information about conditions such as optic neuritis, optic tumors, retinal disorders, and demyelineating diseases such as multiple sclerosis. The anatomical sites of contact for VEP testing are the patient's scalp and possibly other (with the contact object being electrodes that are capable of measuring bio-potentials).

Nerve Stimulation and Monitoring testing is performed by providing low-current electrical stimulation to a patient's nerve tissue during intra-operative/surgical procedures performed by a qualified surgeon. A low-current stimulus (constant-current pulses, etc.) is presented to the subject through the use of a sterile nerve stimulator probe (monopolar or bipolar) or needle electrode which delivers the constant-current electrical stimulus directly to the exposed tissue. The evoked nerve response is recorded through the use of various types of electrodes (sub-dermal, needle electrodes, etc.), amplified/filtered, and digitized (with possible use of averaging) to obtain an evoked response signal. Nerve Stimulation and Monitoring

{5}------------------------------------------------

testing is useful for nerve localization and integrity determination, intra-operative nerve monitoring during surgical procedures (facial, intra-cranial, peripheral, spinal, cochlear, etc.), direct stimulation for evoked responses (EP, EMG), and cochlear promontory stimulation (transtympanic eABR). The possible anatomical sites of contact for Nerve Stimulation and Monitoring testing are the patient's nerve tissue (with the contact object being sterile monopolar or bipolar nerve stimulator probe tips), the patient's tympanic membrane and cochlear promontory (with the contact object being a sterile stimulation needle electrode), and the patient's scalp and possibly other body sites (with the contact object being electrodes that are capable of measuring bio-potentials).

The modifications associated with this new SmartEP modified device only affect the operation of the SEP, VEP, and nerve stimulation/monitoring hardware and software functionality. There are no changes to any part of the AEP functionality. The modified SmartEP device is identical to the original SmartEP device in its intended use and methodologies for AEP testing, which have not changed as a result of modifications to the general or electrical specifications of the device, except with additional indications and capability for somatosensory evoked potential, visual evoked potential, and nerve stimulation/monitoring testing. Thus, the modified SmartEP device can be used to perform the same tests provided by the listed original SmartEP device (i.e., AEP testing), as well as SEP, VEP, and nerve stimulation/monitoring testing.

The original SmartEP device (refer to FDA K904926) consists of the Universal Smart Box (the main hardware receiver unit containing electronic hardware) and external medical grade power supply, power cable, Opti-Amp bio-amplifier (refer to FDA K914876 and K052060), electrodes and leads, sound transducers, Universal Serial Bus cable, a laptop or desktop computer with a Universal Serial Bus port and Windows (2000, XP, Vista) operating system, along with SmartEP software.

For SEP testing, unlike the original SmartEP device, the modified SmartEP system also requires a separate SEP Electrical Stimulation Box and SEP Electrical Stimulator Probe to deliver a constant current electrical stimulus (through two metal prongs or skin-surface electrode connections) to the patient to elicit an evoked response. The metal prongs of the SEP Electrical Stimulator Probe are made of biocompatible Type-302 stainless steel, which meets the ISO-10993 standard. This commercially available grade of steel is commonly used for non-implant medical devices and dental appliances/prosthesis. The SEP Electrical Stimulation Box/Probe is powered by a medical grade power supply, and the patient is afforded protection and isolation transformer (rated up to 3500 volts DC, 10 TeraOhms). In addition, control hardware and software is used to limit the current stimulation to 0-100mA into a load less than or equal to 4000 Ohms (0-400V).

For VEP testing, unlike the original SmartEP device, the modified SmartEP system also requires a separate VEP Visual Stimulation Box with stimulator LED light array to deliver visual patterns to the patient to elicit an evoked response. In this case, there is no added electrical patient contact. The type of LEDs used for stimulation are commercially available, low-intensity, diffuse, red LEDs with a peak wavelength of 625 nm. The illumination provided by these LEDs is of an eye safe intensity and wavelength according to the FDA/CDRH 21 CFR 1040 Performance Standard for Light-Emitting Products. Considering the maximum radiant output condition with all of the LEDs on simultaneously, the system provides an average maximum accessible emission intensity level of approximately 0.43 microWatts at a distance of 30 cm (12 inches) from the test subject. Due to the narrowband characteristics of the LEDs, there is no significant emission of energy in the infraviolet (UV) region of the spectrum, and therefore no concern about this type of exposure.

For Nerve Stimulation and Monitoring testing, unlike the original SmartEP device, the modified SmartEP system also requires a separate Low-Current Stimulation Box to deliver a constant low-current electrical stimulus to the patient's exposed tissue to elicit an evoked nerve response. A separate nerve stimulator probe (monopolar or bipolar) or needle electrode which connects to the Low-Current Stimulator unit is

{6}------------------------------------------------

also required to provide direct stimulation to the patient, and is provided by an outside vendor prepackaged and sterile. The Low-Current Stimulation Box is powered by a 9V battery, and the patient is afforded additional protection and isolation via an isolation amplifier. In addition, control hardware/software is used to limit the current stimulation to 0-5mA into a load less than or equal to 1500 Ohms (0-10V), and the output channels are capacitively-coupled to prevent the unintended accumulation of direct current (DC) charge.

Figures E-1 and E-2 show simplified block diagrams for the original SmartEP system and the modified SmartEP system with SEP, VEP, and Nerve Stimulator/Monitoring testing functionality.

{7}------------------------------------------------

#### Safety and Effectiveness:

The modified SmartEP device with SEP, VEP, Nerve Stimulation/Monitoring testing functionality utilizes the same design principles, circuit designs, and operating principles as are used in the original SmartEP device. All of the modifications to the SmartEP device were designed in accordance with procedures that meet FDA QSR Design Control and ISO-13485:2003 specifications.

The same Hazard/Risk Analysis was performed for the modified SmartEP device using the same Fault Tree Analysis (FTA) approaches as in the original device. Also, the same validation, verification, and testing techniques for both hardware and software were performed for the modified SmartEP device.

The Class I Accessible Emission safety criteria outlined in the FDA/CDRH 21 CFR 1040 Performance Standard for Light-Emitting Products were followed in terms of the peak wavelength, exposure duration, and radiant intensity level of the light stimulus used for VEP testing. The light output of the device is of an eye safe intensity and wavelength, and meets Class I light product specifications which are not considered to be hazardous.

The safe electrical design criteria outlined in the FDA Guidance Document for Evoked Response Stimulators were followed in terms of isolation, leakage current, and applied current specifications (i.e., pulse width, amplitude, and direct-current decoupling). The patient-connection hardware is basically the same as the original device. There are no newly-introduced hardware related methods by which the patient can be harmed or injured through use of the device. The same patient interface/isolation methods are used.

The modified SmartEP device will be evaluated and certified for both electromagnetic compatibility and electrical safety by a certified National Recognized Test Laboratory (NRTL), which will conduct the appropriate EMI/EMC testing for medical electrical equipment, to elements of the requirements of:

- EN60601-1:1990: "Medical Electrical Equipment, Part 1: General Requirements for Safety." .

#### Product Labeling:

In this 510(k) application there are changes in the intended use, advertisements, and directions for use due to the type of modifications to the original SmartEP device marketed by Intelligent Hearing Systems with FDA 510(k) clearance numbers K904926. These changes only deal with the new Somatosensory Evoked Potential (SEP), Visual Evoked Potential (VEP), and Nerve Stimulation/Monitoring testing aspects of the device. The original Auditory Evoked Potential (AEP) testing aspects have not been changed.

The only changes in product labeling between the predicate device under current 510(k) review are in the additional electrical safety labels (which include the reference model numbers and the power specifications) for the SEP Electrical Stimulation Box, SEP Electrical Stimulator Probe, VEP Visual Stimulation Box, and Low-Current Stimulation Box. These changes are a result of the modifications mentioned in this 510(k). The electrical safety labels for the Universal Smart Box (USB), SEP Electrical Stimulation Box, SEP Electrical Stimulator Probe, VEP Visual Stimulation Box, and Low-Current Stimulation Box are shown in the figure below. Note that power is supplied to the SEP Electrical Stimulator Probe through the SEP Electrical Stimulation Box, and power is supplied to the VEP Visual Stimulation Box through the Universal Smart Box.

Image /page/15/Figure/3 description: The image shows five labels, each with the text "INTELLIGENT HEARING SYSTEMS Miami, FL USA" at the top. Each label also has the year "2006" and a reference number (REF) and serial number (SN). The labels are for different products: USB DSP BOX, SEP ELECTRICAL STIMULATION BOX, SEP ELECTRICAL STIMULATOR PROBE, VEP STIMULATOR BOX, and Low-Current Stimulation Box. The labels also include electrical specifications and safety symbols.

#### Device Name: SmartEP (with Additional/Expanded Indications for Somatosensory Evoked Potential Testing, Visual Evoked Potential Testing, & Nerve Stimulation/Monitoring)

Indications for Use:

SmartEP is an evoked response testing and diagnostic device, that is capable of eliciting, acquiring, and measuring auditory, somatosensory, and visual evoked potential data, as well as providing nerve stimulation and monitoring.

The intended use of the SmartEP device is to objectively record evoked responses from patients of all ages upon the presentation of sensory stimuli. The product is indicated for use as a diagnostic aid and adjunctive tool in sensory related disorders (i.e., auditory, somatosensory, visual) and in surgical procedures for inter-operative nerve monitoring.

The SmartEP system is intended to be used by trained personnel in a hospital, nursery, clinic. audiologist's, EP technologist's, surgeon's, or physician's office, operating room, or other appropriate setting.

The anatomical sites of contact for auditory evoked potential (AEP) testing are the patient's ear canal (with the contact object being a sound delivery eartip or headphone, or an ear probe and personal eartip, or earcup) and the patient's scalp and possibly other body sites (with the contact object being electrodes that are capable of measuring bio-potentials).

The anatomical sites of contact for somatosensory evoked potential (SEP) testing are the patient's upper/lower limbs and head (with the contact object being two metal prongs or skin-surface electrodes connected to a constant-current stimulator probe) and to the patient's scalp and possibly other body sites (with the contact object being electrodes that are capable of measuring bio-potentials).

The anatomical sites of contact for visual evoked potential (VEP) testing are the patient's scalp and possibly other body sites (with the contact object being electrodes that are capable of measuring bio-potentials).

The possible anatomical sites of contact for nerve stimulation and monitoring testing are the patient's nerve tissue (with the contact object being sterile monopolar or bipolar nerve stimulator probe tips), the patient's tympanic membrane and cochlear promontory (with the contact object being a sterile stimulation needle electrode), and the patient's scalp and possibly other body sites (with the contact object being electrodes that are capable of measuring bio-potentials).
