Note: The AortaScan AMI 9700 is not intended to detect, identify, screen for, or diagnose abdominal aortic aneurysms (AAAs). The AortaScan AMI 9700 is quick and easy to use. When the user releases the scan button, the AortaScan AMI 9700 uses patented Vmode® technology to measure ultrasound reflections on multiple planes inside the body and produces a three‑dimensional image within seconds. Based on this image, the AortaScan AMI 9700 calculates and displays the approximate abdominal aortic diameter. A sonographer is not required. If needed, after a scan has been taken, a unique aiming icon guides the operator to optimal probe placement with a comprehensive, three‑dimensional display showing the aorta in two cross‑sectional images verifying that a complete scan has been achieved.
1 Operations & Maintenance Manual: Important Information
AortaScan AMI 9700 measurements can be printed via an onboard thermal printer or transmitted, via a proprietary wireless connection, to a personal computer running HIPAA‑compliant ScanPoint® with QuickPrint software. ScanPoint with QuickPrint software enables the user to print detailed reports for medical records or reimbursement, calibrate the instrument (requires a calibration kit), download and install software updates, and archive data on Verathon® servers.

CAUTION Use of the following cleaning methods or solutions may cause device damage not covered by the AortaScan AMI 9700 warranty. • Do not immerse the instrument in disinfectant solution. • Do not use Cidex Plus® to disinfect the instrument. Cidex Plus will damage the plastic enclosure. • Do not subject any part of the instrument to steam sterilization or ethylene oxide sterilization. WARNINGS WARNING The AortaScan system is not a diagnostic or screening device. If clinically indicated, appropriate patients should be referred for a diagnostic standard (confirmatory) test, regardless of test results.
WARNING The AortaScan system is designed to detect the fluid (blood) filled region of the abdominal aorta only. The system cannot detect the presence of a blood clot (thrombus) and therefore may provide a false negative result.
WARNING The AortaScan system is an ultrasound‑based device and is subject to all limitations of this method. If clinically indicated, appropriate patients should be referred for a diagnostic standard (confirmatory) test, regardless of test results.
WARNING Risk of explosion. If you use the AortaScan AMI 9700 in the presence of flammable anesthetics, the hazard of potential explosion exists.
WARNING Risk of electric shock or burns. Do not use the AortaScan instrument in conjunction with HF surgical equipment.
WARNING Ensure proper distance from patient. The AMI 9700 battery charger/wireless hub and the computer used to access online ScanPoint® image archives (if used) must be placed outside the patient vicinity (more than 2 m [6 ft] from the patient).
5 Operations & Maintenance Manual: Important Information
WARNING Risk of explosion, fire, or serious injury. The AortaScan AMI 9700 is powered by a lithium‑ion battery. Failure to note the following when handling the battery may result in serious injury: • Never short‑circuit the battery by either accidentally or intentionally bringing the battery terminals into contact with any other conductive object. This could cause serious injury or fire and could also damage the battery and/or the instrument. • Never expose the battery to abnormal shock, vibration, or pressure. The battery’s internal protective covering could fail, causing it to overheat or ignite, resulting in caustic liquid leakage, explosion, or fire. • Do not disassemble, heat above 60°C (140°F), or incinerate the battery. Keep battery out of reach of children and in original package until ready to use. Dispose of used batteries promptly according to local recycling or waste regulations. • If the battery is leaking or its case is cracked, put on protective gloves to handle it, and discard it immediately. Always dispose of used batteries in compliance with all applicable laws and regulations. Put insulating tape, such as cellophane tape, on the electrodes during transportation in order to avoid a possible short circuit, fire, or electrical shock.
WARNING Do not use the AortaScan AMI 9700 on: • A patient who has open skin or wounds in the mid‑abdominal area. • A patient with ascites. • A pregnant patient.
WARNING Potential patient hazard. To date, exposure to low‑power, pulsed diagnostic ultrasound has not been shown to produce adverse effects. However, medical professionals should use ultrasound only when clinically indicated, using the lowest exposure times possible to obtain proper measurements. The ultrasonic output of the AortaScan AMI 9700 is not user adjustable and is limited to the minimum level necessary for effective performance. For more information about the acoustic output levels of this device, see the section Product Specifications on page 68.
WARNING Ensure that you follow the manufacturer’s instructions for handling and disposing of the cleaning and disinfection solutions provided in this manual.
6
WARNING Risk of inaccurate measurements/results. When using the instrument, be aware of the following conditions that can decrease the accuracy of exam results: • In some cases, the normal operating tolerances of the instrument can cause it to report a falsely normal or abnormal measurement. For more information, see Interpret the Aortic Measurement Results on page 51. • Visual verification that the aorta position is fully within the scan cone on the displayed images is important. • A thrombus (blood clot) can complicate aortic measurements. A soft, blood‑like thrombus may appear as part of the lumen. However, a calcified thrombus may appear as part of the aorta’s wall, resulting in a measurement of lumen diameter that is smaller than the aorta diameter. Accordingly, in patients where thrombus is known or suspected, other imaging methods should be used prior to ruling out an aneurysm. • Use care when scanning patients who have had abdominal surgery. Scar tissue, surgical incisions, sutures, and staples can affect ultrasound transmission and accuracy. • Ensure that the patient fasts for 12 hours prior to undergoing an aortic diameter measurement in order to minimize the presence of bowel gas, which may obstruct proper measurement. • Obesity may affect ultrasound aortic diameter measurements. For more information, see Obesity on page 54. Accuracy is compromised if the user does not obtain an optimal, repeatable image.
WARNING Cleaning is critical to ensuring the component is ready for disinfection. Failure to properly clean the device could result in a contaminated instrument after completing the disinfection procedure.
WARNING This product may only be cleaned and disinfected by using the approved processes provided in this manual. Cleaning and disinfection methods listed are recommended by Verathon® based on compatibility with component materials.
