Management

GEM®, GEM® II, & GEM® III Family of ICDs

GEM® III DR

GEM III-DR
GEM III DR
Model 7275
Enhanced tachyarrhythmia therapy, safety, and convenience:
  • Fewer unnecessary shocks for patients
  • Greater device longevity (6.1 years using
    15% pacing and quarterly charges)
  • Exclusive Patient Alert™ monitors system for five safety conditions and alerts patients to seek follow-up care if necessary
  • Enhanced diagnostics make follow-up more efficient and effective
  • Medtronic Vision® software and Quick Look™ home page simplify programming
    and follow-up

Proven PR Logic™ analyzes rate, pattern, regularity and AV dissociation to detect and classify arrhythmias and trigger device response:

  • When tachyarrhythmia therapy is delivered, device has 95.2% Positive Predictive Value with enhanced PR Logic™ 
  • When tachyarrhythmia therapy is withheld, device has 100% sensitivity that it is not needed

Ventricular Tachyarrhythmia Therapies:

  • Antitachycardia pacing (ATP)
  • Cardioversion
  • Defibrillation

Dual chamber rate responsive pacing therapy

Common software and programmer for all Medtronic ICDs and pacemakers

Flexible lead choices for specific physician preferences

Delivered output: 0.4 — 30 J within 7 seconds charge time

Remote Monitoring Now Available

“We view remote telemetry, such as that provided by the CareLink Network, as the new standard of care for ICD patients. I expect the technology to increasingly change the way patients with implantable devices are cared for across the country.”

W. Ben Johnson, M.D., an electrophysiologist at the Des Moines-based Iowa Heart Center.

The Medtronic CareLink Network is transforming patient care with the first and only remote monitoring service for device patients and their clinics.
