The Medtronic InSync Maximo™ incorporates proven cardiac resynchronization therapy, high defibrillation safety margin, enhanced longevity, and sophisticated diagnostics to meet each patient's individual needs.

Key Features

Advanced Cardiac Resynchronization + ICD Therapies

  • 35 Joules, high energy output in 9 seconds or less throughout the life of the device1.
  • 6 years of longevity 2 (14% increase in longevity over InSync II Marquis).
  • Separately programmable ventricular outputs for adapting pacing outputs to unique patient needs
  • Special pacing functions to help manage heart failure patients who also experience atrial fibrillation.
  • Painless antitachycardia pacing (ATP) therapy to terminate 3 out of 4 episodes of fast ventricular tachycardia (VT).3
  • Enhanced PR Logic dual-chamber detection to maintain high sensitivity for ventricular tachyarrhythmias while improving discrimination for supraventricular tachycardias. Offers 95.2% accuracy (Positive Predictive Value) in delivered therapies.4
  • Programmable with the Medtronic CareLink® Programmer

Powerful Heart Failure Management and Advanced Patient Alert Capabilities

  • Heart Failure Management Report showing 14-month trends of key heart failure patient monitoring categories such as AT/AF Burden, ventricular rate during AF, heart rate variability, patient activity and night/day heart rates.
  • Observation messages highlighting heart failure related parameters outside of typical ranges.
  • Cardiac Compass® Report with additional information about ventricular arrhythmia detection and therapies.
  • Rate Histogram Report provides information about % pacing during episodes of AF, sinus rate profiles and ventricular rate profile during AF.
  • Advanced patient alert capabilities, including lead integrity, battery condition change, and ICD therapy issues.
  • Remote device follow-up with the Medtronic CareLink Network can dramatically reduce the time and resources required for routine device checks. Patients can use the Medtronic CareLink Service to transmit comprehensive device data using a standard phone line while at home, work or while traveling. Within minutes, clinics can view patient device data from any Internet-enabled PC using the secure clinician website. Learn more.
