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

Wi-Box FAQFor use with ILUMIEN and RadiAnalyzer Xpress

2222

Wi-Box FAQQ: 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.

2323

Wi-Box FAQQ: 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.

2424

Wi-Box FAQQ: 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

2525

FAQ Wi-BoxQ: 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.

2626

Wi-Box FAQQ: 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.

2727

Wi-Box FAQQ: 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.

2828

Wi-Box FAQQ: 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 air2.Zero AO pressure on ILUMIEN or RadiAnalyzer Xpress3.Zero pressure on hemodynamic recording system4.Close AO transducer to air to resume pressure reading

2929

Wi-Box FAQQ: 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 TechnologyPressureWire 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 memory3. In the event of power failure, the Receivers resume communication automatically4. The system utilizes “Frequency-Hopping Spread Spectrum” technology (FHSS) and changes transmitting

frequency randomly at 400 times/s5. The technology minimizes the risk of interference with, or disturbance from, other systems in the cath lab6. Very low radio power further reduces risk of interfering with other systems

Radio Technology FAQQ: 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

3232

Radio Technology FAQQ: 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.

3333

Radio Technology FAQQ: 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
