Abbott subsidiary St. Jude Medical has recalled its Unify and Unify Assura cardiac resynchronization therapy defibrillators due to battery issues. The devices may exhibit premature battery depletion, an FDA [recall notice](http://abbott.mediaroom.com/2017-08-29-Abbott-issues-new-updates-for-implanted-cardiac-devices?ref=fdaweb.com) says. The products are intended to provide ventricular anti-tachycardia pacing and ventricular defibrillation for automated treatment of life-threatening ventricular arrhythmias. The devices may also be programmed to provide single or dual chamber bradycardia pacing, in additional to cardiac resynchronization therapy via left ventricular pacing. Abbott sent a field notification letter dated 8/8, according to the notice.
