Primary Outcome Measures :
  1. Seizure Frequency [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
    The average seizure frequency per month over the last 3 months (by type) will be collected

  2. Maximum Seizure Free Period [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
    The maximum seizure free period over the last 3 months will be collected

  3. Seizure Severity [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
    Seizure severity is a categorical outcome and will be rated by the subject using the following categories: Very mild, Mild, Moderate, Severe, Very Severe

  4. Post-ictal Severity [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
    Seizure severity is a categorical outcome and will be rated by the subject using the following categories: Very mild, Mild, Moderate, Severe, Very Severe

  5. Change in Quality of Life [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
    Quality of life is a categorical outcome and will be rated by the subject using the following categories: Very good: could hardly be better, Pretty good, Good and bad parts about equal, Pretty bad, Very bad: could hardly be worse

  6. Quality of Sleep [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
    Quality of sleep will be reported using the Pittsburgh Sleep Quality Index for subjects 18 years and older and using the Children's Sleep Habit Questionnaire for subjects 2-17 years old; quality of sleep will not be assessed in children under 2 years old

  7. Anti-epileptic Drug Use [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
    The name and dose of anti-epileptic drugs used will be collected on a case report form

  8. Rescue Drug Use [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
    The number of times a rescue drug was used will be collected

  9. Seizure Related Emergency Department Visits [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
    The number of times a patient had a seizure related emergency department (ED) visit will be collected

  10. Seizure Related Hospitalizations [ Time Frame: Baseline, 3, 6, 12, 24, and 36 months after implant; long term follow-up data through 60 months may be collected, if applicable ]
