{0}------------------------------------------------ K080321 Page 1 of 5 # SECTION 6 - Corrected 510(k) Summary MAY 2 3 2008 # SAFETY AND EFFECTIVENESS SUMMARY Safety and effectiveness information concerning the SNAP Model 7 device is summarized below. PREPARED BY: Gil Raviv, Ph.D President SNAP laboratories INT., LLC 5210 Capitol Drive Wheeling, IL 60090 TELEPHONE: (847) 777-0000 FAX: (847) 465-3404 CONTACT PERSON: Gil Raviv, Ph.D DATE ON WHICH THE SUMMARY WAS PREPARED: March 31, 2008 NAME OF DEVICE: SNAP Model 7 ™ COMMON NAME: Snoring and Apnea Recording and Analysis Device CLASSIFICATION NAME: MNR Ventilatory Effort Recorder PREDICATE DEVICE: There are two predicate devices, both being earlier existing versions Snoring/Apnea Recording Systems designed by SNAP Laboratories. These 510(k) #K002095 - SNAP Model 6™ are: ### 510(k) #K992322 - SNAP Model 5™ . The new SNAP Model 7™ employs a combination of features from these two devices. DESCRIPTION OF THE DEVICE: The SNAP Model 7™ system consists of several components, many of them essentially unchanged from the predicate devices. The componently many of the Model 7 Data Recorder, which is an updated design design modification to the Model 6 predicate device. Other major elements of the system are modificultion to the moder o phich run on a PC in the physician's office, and the data analysis software located on computers at the SNAP laboratories central location. The andiyals bonward routines for setup, control and data transfer, whereas the GUI is a high-level program which provides the interface between the user (doctor's office) and the DLL. The DLL/GUI software is similar to that of the Model 6 predicate device, except that the rne been of the recorder is transferred to the computer via USB communication instead of data from the roofder lorive cartridge. Also, the Model 6 interface was via serial port. {1}------------------------------------------------ K080321 Page 2 of 5 The data analysis software is unchanged from that which is used in the predicate devices. The SNAP Model 7™ Data Recorder is a small DC powered device designed to be simple and easy to use by a patient. It is self-contained, with integrated microcontroller and LCD display and all necessary interface electronics to perform all system recording functions. It does not require connection to a host computer in order to perform the recording functions. The data recorder consists of the physical hardware and firmware that interfaces to the patient to collect the physiological data. The recorder has sensors to collect sound, pulse oximetry, respiration effort (belt), and body position. The information is digitized and stored on a removable solid state memory card. The data on the removable data card is accessed through a USB port on the device, connecting to a PC running the DLL software. The DLL software provides the interface for all communication between the recorder and the computer in the doctor's office. This DLL handles the low-level USB communications as well as parsing and storing intermediate files on the connecting computer. The DLL also interacts with a higher-level GUI client application. The GUI calls DLL functions to interact with the data recorder. The GUI also interacts through the Internet with the central website to transfer the patient data, and provides various data entry functions. The GUI calls DLL functions to program the recorder, check status, clear memory, check USB connectivity, retrieve serial number, retrieve patient data, get time, etc.. The GUI interacts with the website to identify the patient for the programming step and to transfer the collected patient data to the web server. The GUI also functions as a dedicated browser to the website, to navigate the website and identify the patient (and optionally enter new patient information). Once the patient is selected, the recorder is programmed with information regarding the patient name and which sensors are required for the test. After the programming is completed, the patient goes home with it and following the instructions for connection and startup prior to going to sleep. After the patient uses the recorder to collect overnight sleep data, the recorder is returned to the doctor's office, connected to the DLL/GUI computer via the USB port, where the patient data record is programmatically matched to the on-line patient record. After a manual confirmation step, the intermediate files are zipped up and uploaded (via secure, encrypted https) to the web server. The GUI functions as a dedicated web browser to the website. This allows the GUI to be used for the various data entry steps. The website stores patient information, patient reports, and serves as a "way station" for the raw patient data before it get processed by the data analysis component. Demographic information is collected for the patient along with insurance and credit-card information. Contact and identifying information is collected for the patient's referring physicians. The test results are delivered to the referring physician based on this information. Access to the website is login and password protected. Various roles and user types are in place to safeguard inappropriate access to patient information. All pages of the website run in secure mode (https). The data analysis follows a pre-existing procedure that is already in place for earlier recorder models. The patient data from the website is securely downloaded to analysis workstations at SNAP Laboratories for analysis and processing. The resulting report is then securely uploaded back to the website so it can be made available to the referring physician by a transfer mechanism of their choice. {2}------------------------------------------------ ### INTENDED USE: The Model 7TM device is indicated for use in the diagnostic evaluation of patients for apnea and snoring and to provide quantitative and qualitative analysis of apnea and snoring. The SNAP Model 7™ testing system is not intended as a substitute for full polysomnography when additional parameters such as sleep stages or EEG activity are required. The target population consists of patients who are suspected of apnea and/or complain about snoring. The majority of the test procedures will take place at the patient's home, although some may take place in a sleep laboratory. Both pediatric and adult patients may be tested. CAUTION: US Federal law restricts this device to sale by or on the order of a physician. Use of this device must be under the direct supervision of a qualified adult (parent or guardian) or health care practitioner trained in the use of the SNAP Model 7 ™ device. PATIENT POPULATION: Adults and pediatric patients. ## SAFETY AND EFFECTIVENESS SUMMARY The SNAP Model 7™ is an evolutionary design modification to the above-listed predicate devices. It is physically similar to the SNAP Model 6™, in that it is a small, separate recorder located in the general vicinity of the patient, with all sleep sensors connected from the patient to the recorder box. As with all SNAP devices, there are no electrical connections to the patient. In addition, the Model 7 uses a medical grade power supply, and there are no exposed metal connectors or controls, further minimizing any electrical risk to the patient or the user. The Model 7 has been tested and certified to the International Standard EN 60601-1-2:2005, the accepted EMC/EMI standard for medical devices. The sensors, transducers and accessories used with the Model 7 are the same as those used with one or more of the predicate devices, and all instructions for use, for Recorder, oximeter, respiratory effort belt, etc., are appropriate for their intended use. The PC computer interface to the Model 7 is via the USB interface, the current standard for simple and effective computer accessory connections. The Model 6 predicate device uses a similar (but obsolete) serial port interface. The Model 5 predicate device did not use a separate hardware Recorder. The program running on the PC in the doctor's office (used for Recorder setup and data uploading from the Recorder) is very similar to that used with the Model 6 predicate device, except for changes in communication protocols required because of the change from serial port to USB, and changes as required because of the different Recorder hardware. The Model 5 predicate device introduced the use of secure data transmission over the Internet for uploading patient data and demographic information to the SNAP Laboratories central {3}------------------------------------------------ K080321 Page 4 of 5 location for analysis and reporting. The Model 7 uses this same method, basically unchanged from that used with the Model 5, to enable the software running on the doctor's office computer to connect to the central data analysis site via the Internet. The SNAP data analysis software, which runs on PC computers at the SNAP Laboratories central location, is essentially unchanged from that used with both predicate devices. The secure https:// method for secure data transmission, using data encryption methods standard with most high-security financial transactions, is employed by the Model 7 software. Analysis is performed and reports are generated at the SNAP laboratories central site, and these reports are faxed to the physician and/or placed onto the SNAP Labs web site for access and retrieval by the referring physicians. | Characteristic | SNAP Model 7 - Subject of this 510(k) | Predicate Device SNAP Model 5 | Predicate Device SNAP Model 6 | |----------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------| | Labeling | The User's Manual and device labeling has been updated to show new configuration and operational information.
