Features


    Downsize Without Compromise
    With the smallest footprint of any CRT-D available, insightful diagnostics and an unprecedented 40 J in delivered energy, the Unify CRT-D is downsized without compromising on energy, longevity, safety or reliability.

    Smaller
  • The smallest footprint of any high voltage device available for a smaller incision and reduced pocket size
  • QHR®** chemistry battery provides greater capacity for enhanced longevity and charge times
  • DF4 connector is designed to simplify implants by streamlining defibrillation connections into a single terminal pin and reducing the number of set screws
  • Decreased device footprint and volume with the most narrow (40 mm) design available for greater patient comfort and range of motion during activity

    Smarter
  • The addition of antitachycardia pacing (ATP) prior to and while charging in the VF zone further extends the programming options for converting tachyarrhythmias painlessly.
  • 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.
  • The % BiV-Pacing alert notifies clinics when percent biventricular pacing is less than the programmed threshold.
  • Advanced Biventricular Pacing options:
  • VectSelect® programmable LV pulse configuration (LV ring-RV coil, LV tip-RV coil or LV bipolar) may be adjusted noninvasively via the programmer.
  • Triggered Pacing with BiV Trigger Mode helps maintain a high percentage of BiV pacing by triggering pacing in both the left and right ventricles in response to a sensed ventricular event.
  • Negative AV hysteresis with search promotes ventricular pacing by automatically reducing the AV delay when intrinsic activity is present, thereby promoting a high degree of ventricular pacing.
  • QuickOpt® timing cycle optimization provides quick and effective optimization for more patients at the push of a button.1
  • The low frequency attenuation filter is designed to enhance sensing performance and may reduce the possibility of oversensing T waves.
  • The unique SenseAbility® feature, with Decay Delay and Threshold Start, provides the flexibility to fine-tune sensing to individual patient needs.
  • Unique AF Suppression™ algorithm is clinically proven to suppress episodes of paroxysmal and persistent AF. Studies show a 25% decrease in symptomatic AF burden.2

    Stronger
  • The unique 40 J Safety Shock provides a greater DFT safety margin and may minimize the need for multiple DFT tests at implant or extra hardware.
  • DeFT Response® technology tools provide more clinically proven, noninvasive options for managing high DFTs.
