Defibrillation Leads

Clinical Evidence

Proven Lead Reliability

Independent Fluoroscopic and Electrical Assessment Confirm Durata Lead Reliability1

The Forleo, et al. single-site study was the first systematic fluoroscopic and electrical assessment of Optim™ insulation coated leads (n=413 overall: 225 high voltage, 188 low voltage).

  • Average follow-up time was 25.7 +/- 14.1 months.
  • During the total follow-up of 10,036 lead-months, there were 7 Optim lead failures.
  • Fluoroscopic screening detected no cases of externalized conductors.

Independent Study from VA Hospitals Experience Supports Durata Lead Reliability2

An analysis of more than 4,400 leads with Optim™ lead insulation with up to seven years of follow-up from the VA National Cardiac Device Surveillance Program2 shows:

Minimizes Lead Abrasion

The Durata lead uses Optim lead insulation, which is supported by evidence from approximately 11,130 leads actively monitored in prospective registries, more than 40,000 patient years of data and multiple third-party publications.4 Postmarket surveillance of these leads demonstrated that there were ZERO reported instances of externalized conductors in the study.5


Clinical Intel: Excellent Long-Term Performance of Abbott ICD Leads Reinforced by ESC Presentation5

  • This multi-center prospective study evaluated long-term performance of Durata ICD leads
  • A total of 11,132 patients were followed over a period of 11 years – reflecting three prospective registries (beginning in 2006)
  • Potential instances of lead failure were adjudicated by an electrophysiologist: There were ZERO reported instances of externalized conductors in the study
    • The all-cause mechanical failure rate (0.29%/yr.) reported in this study exceeds industry benchmarks
    • Furthermore, the data also includes returned products and non-returns, resulting in an incidence rate that is a true reflection of real-world performance
  • This study builds on the earlier publications from HRS, and reinforces our excellent record of long-term ICD lead survival
