Percentage of Participants Not Experiencing a System or Procedure Related Complication Through 5-years Primary · 5 years

The 4-SITE Lead/Header System will be evaluated based on the "chronic 4-SITE Lead/Header System-related complication-free rate" for the five (5) year follow-up period after the index implantation. The primary endpoint analysis will include confirmed chronic 4-SITE Lead/Header System-related complications that result in study subject permanent loss of therapy, invasive intervention, injury or death.
