The U.S. FDA has approved St. Jude Medical’s radiofrequency (RF) wireless devices to treat patients with heart failure and with potentially lethal heart arrhythmias.

The new devices, the Promote RF cardiac resynchronization therapy defibrillator and Current RF implantable cardioverter defibrillator, feature RF telemetry for wandless communication, according to the St. Paul, Minn.-based medical device company.

The firm also said that the devices use a range of frequencies designated for medical devices called the medical implant communications service frequency band, which prevents interference from other electronic signals.
