Unify Quadra™ CRT-D

This device is commercially available for use in select international markets.

Quadripolar Technology in a Downsized Device

UNIFY_QUADRA_CD3251-40Q_3quarter_BlkBG_700x227px

The Unify Quadra CRT-D and Quartet™ LV pacing lead feature first-to-market quadripolar technology in a downsized device. With four electrodes and ten pacing configurations, this innovative CRT system enables LV pacing at the preferred site without compromising lead stability for better management of heart failure patients.

Other Key Features:

  • ShockGuard™ technology with DecisionTx™ programming designed to reduce inappropriate therapy and minimise the need for programming adjustments at implant
  • Streamlined header connectors (IS4-LLLL/DF4-LLHH) reduce pocket bulk
  • QHR™ battery provides greater capacity for enhanced longevity and improved charge time performance
  • Antitachycardia pacing (ATP) while charging and prior to charging in the VF zone further extends the programming options for converting tachyarrhythmias before or during charge
  • The % BiV-Pacing alert notifies patients and their clinics when percent biventricular pacing is less than the programmed threshold
  • BiVCap™, LVCap™, RVCap™ and ACap™ Confirm features promote patient safety by automatically ensuring capture of the myocardium in response to pacing stimuli in the left ventricle, right ventricle and right atrium
  • DeFT Response™ technology tools provide more clinically proven, noninvasive options for managing high DFTs
  • QuickOpt™ timing cycle optimisation provides quick and effective optimisation for more patients at the push of a button
