Hydrix Medical introduces


Innovative FFR technology for cardiac intervention procedures

Emerging new technology to help increase procedure safety and improve deployment of life-saving stents

In a typical angiogram procedure, a technology called Fractional Flow Reserve (FFR) is often used to measure blood pressure differences either side of a coronary artery stenosis to determine the amount of blood flow to the heart muscle. This information helps to determine if interventional treatment such as a stent is required.

The Phyzhon PHYRARI FFR-Wire is a ground-breaking technology enabling cardiologists to combine diagnosis procedures with delivery of therapy including stents.

Approximately 125,000 coronary angiograms are
performed each year in Australia

Leading to 60,000 Percutaneous Coronary
Intervention (PCI) procedures

During which 12,000 FFR measurements are taken to
determine whether to stent the artery or not

Clinical trials

Hydrix will be facilitating FIH trials of the Phyzhon PHYRARI-FFR in CY22
