St. Jude Medical (NYSE:STJ) inked a deal to have its PressureWire Aeris fractional flow reserve technology offered with Philips’ (NYSE:PHG) Xper Flex Cardio physiomonitoring system.

FFR is a measurement of the severity of coronary artery blockage. St. Jude’s wireless device links with cardiac catheterization lab systems to track and log FFR measurements during coronary intervention procedures such as angiography.

After two years, patients whose physicians used the PressureWire during coronary stenting had a 34 percent lower risk of heart attack or death compared with angiography alone, the company said.

St. Jude also touted the device’s cost efficiency, saying the PressureWire system saved about $2,000 per angiography, a 14 percent decrease between the two cohorts of its FAME clinical trial.

Philips is the latest feather in the PressureWire cap, following deals with GE (NYSE:GE), Mennen, McKesson (NYSE:MCK) and Siemens (NYSE:SI) to integrate it into their respective cath lab recording systems.
