COGNIS™ Cardiac Resynchronization Therapy Defibrillator (CRT-D)

The smallest, thinnest, high-energy CRT-D in the world

At 9.9 mm thin and only 32.5 cc, the COGNIS CRT-D is a full-featured device, offering improved safety design, enhanced diagnostics, and more flexible programming options—while providing excellent device longevity.

SmartDelay™ AV Optimization

• In the CRTAVO study, SmartDelay optimization for atrial sensing was 98% correlated to the accurate and reliable invasive pressure measurement LV dP/dtmax. For atrial pacing, the correlation was 96%¹
  
• Designed to recommend an optimal AV delay to maximize LV dP/dtmax in 2.5 minutes or less
  
• Independently determines paced and sensed AV delays based on three inputs:
• Intrinsic conduction characteristics (sensed and paced AV intervals)
• Interventricular timing
• LV lead location

Atrial Arrhythmia Management

• Biventricular (BiV) Trigger helps deliver resynchronization therapy as prescribed.
  
• When used with VRR (Ventricular Rate Regulation), BiV Trigger can increase the percent of ventricular pacing during conducted atrial tachycardias and AF episodes.

Enhanced Cardiac Resynchronization Therapy

• Works with a broad portfolio of LV leads designed to provide stability for a wide variety of venous anatomies
  
• Four LV lead fixation designs have an overall implant success rate of 97%.²
  
• Expanded Electronic Repositioning™ provides even more options to clinically manage CRT pacing post-implant, including six pacing vectors with a bipolar LV lead and two pacing vectors with a unipolar LV lead

Assurance

• Designed, built, and tested through Aurora, Boston Scientific Cardiac Rhythm Management’s continuous quality improvement program
  
• Engineered for safety with rigorously tested self-correcting software and Safety Core™ redundant back-up hardware

The COGNIS CRT-D provides important advances designed to help you give your patients the individualized therapy you expect and they need.

¹ CRTAVO data were prospectively collected. However, the data analyses were not prespecified. Refer to Appendix F in the COGNIS System Guide for clinical data on the hemodynamic performance of this feature.
² ACUITY™ Spiral U.S. clinical study. The ACUITY Spiral success rate with EASYTRAK® family was 97.2%. Data on file.
