Fortify Assura™

Implantable Cardioverter Defibrillator (ICD)


Unique Features: Shockguard Technology

For protection against inappropriate and unnecessary shocks, our Fortify Assura™ ICD utilizes expanded ShockGuard technology.

  • Reducing shocks correlates with increased quality of life.1
  • DecisionTx™ programming allows for better discrimination of arrhythmias, resulting in the most appropriate therapy for the patient.
  • Far Field MD™ morphology discrimination algorithm improves upon the use of near-field morphology analysis alone, further reducing inappropriate therapies.
  • Chamber Onset discrimination algorithm utilizes both atrial and ventricular interval information for rhythm diagnosis, determining which chamber is driving the arrhythmia.
  • SecureSense™ RV lead noise discrimination algorithm (non-sustained SecureSense™ episodes) differentiates lead noise from true ventricular tachycardia (VT)/ventricular fibrillation (VF) episodes, providing the ability to automatically withhold tachycardia therapy in the presence of lead noise.

Patient Safety Enhancements

DynamicTx Over-current Detection Algorithm

DynamicTx over-current detection algorithm feature provides the opportunity for devices to deliver a shock, and possibly terminate a VT/VF episode, even in the presence of a compromised lead.

  • Checks for compromised vector integrity
  • Attempts to find a viable configuration to deliver high voltage therapy, while avoiding a problematic vector


TailoredTherapy™ Features

Our exclusive, customizable TailoredTherapy features allow you to individually adjust programming to meet the unique needs of each patient, delivering precise therapy, every time. These innovative features include:

  • DeFT Response™ technology
  • Complete capture confirmation
  • Automatic pacing outputs, periodically measured and adjusted, for optimal therapy delivery in every chamber of the heart


Building Comprehensive Cardiac Rhythm Management

The Fortify Assura ICD is part of our cardiac rhythm management portfolio. Our vision is to transform the treatment of cardiac arrhythmias by designing cost-saving technologies that improve therapy outcomes.
