Link Wi-Box with ILUMIEN System
(Before first FFR procedure)
Link Wi-Box with ILUMIEN
 The Wi-Boxes in each room are the source of AO pressure
 AO pressure and PressureWire™ Aeris™ enable ILUMIEN to
measure pressures and calculate FFR
 Each Wi-Box in all rooms must be linked to a unique room setup
profile on the ILUMIEN console
 It is important to make sure that the correct Wi-Box is linked to the
correct room
 If a Wi-Box is moved to another room, the room profile on the
ILUMIEN console must be updated with the new room
IMPORTANT
To simplify identification of each Wi-Box, it is advisable to power
off all Wi-Boxes by disconnecting them from the cath lab recording
system until they are being linked with ILUMIEN.

Wi-Box FAQ
For use with ILUMIEN and RadiAnalyzer Xpress
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.
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 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.
23
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
24
FAQ Wi-Box
Q: On some recording systems, an arbitrary pressure value can be seen onscreen 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.
25
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.
26
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.
27
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
28
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

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

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
31
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
(0.000070), which is 1000 to 10.000 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.
32
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
