PressureWire™ Aeris™
Features and Benefits
1
Best Practice – True FFR Integration
Utilize existing equipment
Hemodynamic recording systems can be upgraded to a fully integrated, wireless measurement
system for Fractional Flow Reserve (FFR).
Instant access
Improves cath lab workflow and simplifies the FFR procedure by eliminating the need for
standalone instrumentation and time consuming setup.
No cables
PressureWire Aeris’ radio technology eliminates cables crossing the sterile field barrier, limiting
movements, which improves maneuverability of the wire.

PressureWire Aeris - Benefits
1. Utilize existing equipment
PressureWire Aeris and Integrated FFR
• Utilizes existing hardware installation with existing
screens, controls and front-end modules.
• All FFR results are displayed on the existing cath lab and
control room screens.
• Requires only an FFR software upgrade and one
PressureWire Receiver on the cath lab table rail. No
additional permanent cabling is required.

2. No cables required
PressureWire Aeris and Integrated FFR
• The secure, wireless connection between PressureWire
Aeris and PressureWire Receiver eliminates cables crossing
the sterile field barrier.
• Simplifies the procedure and improves wire handling.

3. Familiarity means easy to use
PressureWire Aeris and Integrated FFR
• All FFR calculations and display are in the same familiar recording
system environment that the staff uses for every case, every day.
• The amount of extra training required for the FFR upgrade is very
small.

4. All results in the patient archive
PressureWire Aeris and Integrated FFR
All FFR results and hemodynamic information are stored in the existing
hemodynamic archive, with all other data including angiographic images,
for a complete patient record.

5. True FFR Integration reduces complexity
PressureWire Aeris and Integrated FFR
With all FFR calculation performed in the hemodynamic recording
system, there is no need to connect and balance AO and ECG
signals with another system.

6. Use any IVUS system
PressureWire Aeris and Integrated FFR
• This FFR solution can be installed in any cath lab with a
hemodynamic recording system that is FFR compatible,
regardless of which IVUS system the cath lab has or
may invest in in the future.
• The FFR upgrade may be installed in cath labs with existing
Volcano s5iTM Imaging System.

PressureWire Aeris Overview
 Hydrophilic 0.014” (0.36 mm) pressure guidewire with a pressure transducer 3 cm
from the tip and a detachable battery-operated transmitter.
 Wireless, secure radio connection with PressureWire™ Receiver.
 Used for FFR measurement. There is no need to exchange PressureWire for a
guidewire for placement of stents and balloons.
 Available in 175 cm and 300 cm (US only).
 Both guidewire and transmitter are single use and are disposed of using standard
cath lab protocol for contaminated material.

Communicates via radio with PressureWire Aeris
Automatically zeroes pressure when turned on
Do not turn off the transmitter while inside the body, as this would
require removal from the body and re-zeroing
Normal battery operating time: 3 hours

PressureWire Receiver
 Radio receiver for pressure from PressureWire Aeris.
 Connects directly to a free pressure port in the hemodynamic recording system.
 PressureWire Receiver is mounted permanently on the horizontal cath lab table rail or
on a vertical instrument pole.
 Pressure and FFR measurement is displayed on existing screens of recording system in
control room and in cath lab.
 PressureWire Receiver is powered by the recording system front end and requires no
extra connection or battery.

PressureWire Transmitter and PressureWire Receiver lock to each other
at calibration using a unique identification code.
PressureWire Receiver stores the last connected PressureWire Aeris in its
memory.
In the event of power failure PressureWire Receiver resumes
communication.
Uses “Frequency Hopping Spread Spectrum” technology (FHSS), to avoid
interference with or disturbance from other systems in the cath lab.
Transmits using very low radio power.
