Starting an FFR Case with Wi-Box Solution and RadiAnalyzer Xpress
1.Roll in and turn on RadiAnalyzer Xpress 2.Connect the RadiAnalyzer Xpress Wi-Box cable between AO IN on RadiAnalyzer and XPRESS/PSU on Wi-Box Note: To enable PressureWire reading on the recording system, a cable may be connected between PW OUT on RadiAnalyzer Xpress to the recording system. It is recommended to omit this cable for mobile RadiAnalyzer Xpress usage in order to simplify FFR workflow. FFR Procedure with Wi-Box and RadiAnalyzer Xpress Roll in RadiAnalyzer Xpress and connect to Wi-Box Adapter cable AO transducer cable AO transducer Recording SystemRadiAnalyzer Xpress AO IN
Zero AO on RadiAnalyzer Xpress 1.Select CAL AO(Pa) and press ENTER 2.Open AO transducer to air and press ENTER FFR Procedure with Wi-Box and RadiAnalyzer Xpress Note: If the Auto Setup sequence is activated, the first step (Zero cathlab) must be skipped by pressing ENTER on the remote control
Cal PressureWire 1.Select CAL WIRE(Pd) and press ENTER 2.Flush the PressureWire packaging coil, place flat and press ENTER Note: If the Auto Setup sequence is activated, the first step (Zero cathlab) must be skipped by pressing ENTER on the remote control FFR Procedure with Wi-Box and RadiAnalyzer Xpress
Equalize and record FFR (Same procedure as without Wi-Box) 1.Advance PressureWire until its pressure sensor is placed at the opening of the guide catheter 2.Flush catheter from contrast and make sure to close all valves, remove wire introducer 3.Equalize AO and PressureWire pressures using the Equalize function on the RadiAnalyzer Xpress 4.Advance PressureWire to region of interest 5.Induce hyperemia per standard cath lab protocol 6.Press Rec to record pressure, press stop to review recording and FFR Refer to instructions of use for RadiAnalyzer Xpress for full FFR or CFR procedure instructions. FFR Procedure with Wi-Box and RadiAnalyzer Xpress
1.Press ENTER to skip first step and continue 2.Open AO transducer to air and press ENTER 3.Flush the PressureWire packaging coil, place flat and press ENTER Using Wi-Box and RadiAnalyzer Xpress with the Auto Setup Sequence Note: If PW OUT on the RadiAnalyzer Xpress is connected to the cath lab recording system, the first step is necessary to balance RadiAnalyzer Xpress PW OUT with PW IN on hemodynamic recording system
Re-Zero AO pressure transducer If the AO pressure transducer needs to be re-zeroed during the case, both the AO IN on RadiAnalyzer Xpress and the AO pressure channel on the hemodynamic recording system need to be zeroed: 1.Open AO transducer to air 2.Zero AO on RadiAnalyzer Xpress 3.Zero AO on hemodynamic recording system Note: The order of steps 2 and 3 is not important. Miscellaneous
Wi-Box FAQ For use with ILUMIEN and RadiAnalyzer Xpress
22 Wi-Box FAQ Q: Since the Wi-Box is permanently placed between the AO transducer and the hemodynamic recording system, is there a risk for erroneous readings, inaccuracy or time delay? Answer: The Wi-Box is an electrical circuit listening to the pressure from the connected AO transducer and transmitting the pressure via radio to a receiver. Electrically, the AO transducer is still directly hardwired to the hemodynamic recording system through the Wi-Box. The Wi-Box does not change the accuracy of the pressure read by the hemodynamic recording system. There is no time delay through the Wi-Box; if one pressure is passing through the Wi-Box and one is directly connected to the recording system, there is no difference in time delay between the two pressure readings.
23 Wi-Box FAQ Q: Since the Wi-Box is permanently placed between the AO transducer and the hemodynamic recording system, is there a risk for AO failure during normal cath lab operation – not involving ILUMIEN or RadiAnalyzer Xpress? Answer: The Wi-Box is designed with a direct, hardwired connection between the AO transducer and the hemodynamic recording system. Even in the unlikely event that the software or electronics in the device would fail, the AO pressure is still passed straight through the device to the recording system. Pressure is still passed through the Wi-Box, even without power supply. If for any reason the user wishes to disconnect the Wi-Box, simply unplug the AO transducer cable from the adapter cable and plug it straight into the hemodynamic recording system, bypassing the Wi-Box.
24 Wi-Box FAQ Q: With the Wi-Box between the AO transducer and the hemodynamic recording system, how does the lab zero the AO pressure during a case that does not involve FFR? Answer: The AO pressure is zeroed exactly as it is without the Wi-Box – by opening the AO transducer valve to air and zeroing the corresponding pressure channel on the hemodynamic recording system
25 FAQ Wi-Box Q: On some recording systems, an arbitrary pressure value can be seen on- screen when the AO transducer is disconnected from the Wi-Box – why? Answer: Some hemodynamic recording systems automatically detect when an AO transducer is disconnected. This enables the system to stop displaying pressure when the AO transducer is disconnected after a case, between patients. With the Wi-Box always connected to the pressure port, the hemodynamic recording system may not detect when the AO transducer is disconnected and will keep displaying pressure coming in from the Wi-Box. Without an AO transducer connected, the pressure reading from the open-ended connector will be an arbitrary, random, pressure value. This phenomenon does not affect the pressure reading when there is an AO transducer (with a patient) connected; the problem is limited to possible confusion when seeing an arbitrary pressure value on the screen between cases. If, for any reason, the user wishes to disconnect the Wi-Box, they can simply unplug the AO transducer cable from the adapter cable and plug it straight into the hemodynamic recording system, bypassing the Wi-Box.
26 Wi-Box FAQ Q: Can the Wi-Box transmit AO pressure to ILUMIEN at the same time it is connected to a RadiAnalyzer Xpress? Answer: Yes, Wi-Box is capable of simultaneously providing AO pressure to ILUMIEN and RadiAnalyzer Xpress if they are used in the same room at the same time. However, if a power supply unit is required to operate the Wi-Box, it is not possible to also connect to a RadiAnalyzer Xpress, since the power supply unit uses the same port.
27 Wi-Box FAQ Q: Why is a power supply sometimes required and sometimes not? Answer: The Wi-Box is designed to work using only the excitation voltage provided by the invasive pressure port on the hemodynamic recording system, without the need for an additional power supply. Some combinations of recording systems and AO transducers may limit the available power to the Wi-Box; if this occurs the NOT READY light on the Wi-Box will light up after the AO transducer is connected. In this case, an additional Power Supply unit is required to power the Wi-Box. Electrical power requirements Power Input: 2.4 to 8 VDC For 2.4 to 4 VDC, use Wi-Box External Power Supply Electrical requirements AO transducer: Input impedance >270 Ohm For complete technical specifications, refer to the Wi-Box IFU.
28 Wi-Box FAQ Q: What troubleshooting steps should be performed if the AO pressure is not identical on the ILUMIEN/RadiAnalyzer Xpress and the hemodynamic recording system? Answer: 1.Open the AO transducer to air 2.Zero AO pressure on ILUMIEN or RadiAnalyzer Xpress 3.Zero pressure on hemodynamic recording system 4.Close AO transducer to air to resume pressure reading
29 Wi-Box FAQ Q: How does the Wi-Box connect with ACIST or similar contrast injectors with a built in AO transducer? Answer: The Wi-Box always connects between the AO transducer and the cath lab recording system If there is a ACIST device, Wi-Box connects between its AO transducer and the hemodynamic recording system Hemodynamic Recording system Wi-Box ACIST with AO transducer Adapter Cable Monitor Cable
30 Secure Radio Technology PressureWire Aeris and Wi-Box utilize advanced radio technology to ensure a stable and secure communication with ILUMIEN/Xpress and to avoid disturbing other systems. 1.Transmitters (Aeris and Wi-Box) and Receivers (inside ILUMIEN) lock to each other using unique identification codes stored in the transmitters 2.The Receiver stores the last connected transmitter in its memory 3.In the event of power failure, the Receivers resume communication automatically 4.The system utilizes Frequency-Hopping Spread Spectrum technology (FHSS) and changes transmitting frequency randomly at 400 times/s 5.The technology minimizes the risk of interference with, or disturbance from, other systems in the cath lab 6.Very low radio power further reduces risk of interfering with other systems 400 hops/s 79 channels PressureWire Aeris Transmitter PressureWire USB Receiver Wi-Box Transmitter AO USB Receiver
31 Radio Technology FAQ Q: Can the radio signal be disturbed by mobile phones, Wi-Fi networks, X-ray, etc? Answer: No. PressureWire Aeris and Wi-Box utilize an advanced radio technology called "frequency hopping" where the information is sent several times using multiple radio frequencies. The system changes radio frequency 400 times per second, which means that even if there are several interfering radio sources, the signal will reach the receiver on other frequencies Extensive, real-life cath lab testing has been performed without interruption of radio communication
32 Radio Technology FAQ Q: Can PressureWire Aeris or Wi-Box cause disturbances to other cath lab systems? Answer: PressureWire Aeris and Wi-Box are designed to interfere as little as possible with other radio devices The transmitted radio power is very low - max 1 mW (0.001) and average 70 μW ( ), which is 1000 to times lower than the power from a normal cellular phone The frequency-hopping technique further reduces the risk by transmitting on each frequency for only a very short time The lead enclosure in cath labs reduces the amount of radio power emitted from inside the cath lab. PressureWire Aeris and Wi-Box have passed all radio acceptance tests by US FCC and EU R&TTE.
33 Radio Technology FAQ Q: Can several pairs of PressureWire Aeris/Wi-Box and ILUMIEN/Receivers be used at the same time in the same environment? Answer: Yes. At the start of a procedure, PressureWire Aeris and Wi-Box lock to ILUMIEN using a built-in unique identifier code ILUMIEN can only receive pressure from one connected PressureWire Aeris and one Wi-Box regardless of any other devices used in the same environment The frequency-hopping scheme is random, which means that several pairs of PressureWire Aeris, Wi-Boxes and ILUMIEN systems can communicate in the same environment without disturbing each other
