PressureWire™ X Guidewire

The PressureWire™ X Guidewire in the Cath Lab

Secure Communication¹

The PressureWire™ Transmitter and Receiving System lock to each other at calibration using a unique identification code. The receiver cannot receive signal from any other PressureWire™ X Guidewire used simultaneously in the same environment.

Other elements to ensure secure communication include the following:

• The system uses advanced frequency-hopping spread spectrum (FHSS) technology and very low radio power to avoid interfering with or being disturbed by other systems in the cardiac cath lab.
• Mobile phones, computer networks or x-ray equipment will not disturb the radio signal.
• The PressureWire™ X Guidewire uses extremely low transmitted radio power—1,000 to 10,000 times lower than the power from a normal cellular phone—to reduce the possibility of disturbing other systems.
• The PressureWire™ X Guidewire has passed all radio acceptance tests by US FCC.

* Pa: proximal coronary pressure; Pd: distal coronary pressure
