Minimizing risks

Longer lasting battery means fewer replacements and reduced risks.3

Reducing costs

Fewer device replacements means reduced cost for patients, payers, and the healthcare system.4


EnduraLife Battery Technology works for up to 13.2 years, outlasting the competition.*

Physician perspective on device longevity

Clinical Data

Outlasting the competition

Devices with EnduraLife Battery Technology are lasting longer than comparable devices from both Medtronic and Abbott, as shown in nine independent clinical studies with over 11,314 patients. 5-13

CRT-D survival data

Study results

An original research study in cardiac resynchronization therapy (CRT) was published in 2020 highlighting EnduraLife Battery Technology in Boston Scientific CRT-D devices. Key findings highlight BSC 2.1-Ah EnduraLife batteries exceeding CRT-D patient survival compared to 1.0-Ah batteries³: this is the first study to report implantable cardioverter defibrillator (ICD) battery life exceeding patient survival in a chronic heart failure cohort.

  • Patient death resulted in substantially more devices out of service than battery replacement and avoided costs of complications and generator changes
  • The results help to explain the elevated risks of CRT-D generator changes in shorter-longevity devices

The authors stated that “Device longevity exceeding patient survival addresses a known clinical and economic burden and may result in fewer complications, increase the cost-effectiveness, and would be more in line with patient preferences.”

Device Longevity in Cardiac Resynchronization Therapy Implantable Cardioverter Defibrillators Differs Between Manufacturers: Data from the Danish ICD Registry. Presented at HRS 2014. Boston Scientific = 136 patients, Medtronic = 6 51 patients, St. Jude Medical = 1,587 patients, Bitronik = 369 patients. Time to exchange of the device because of battery depletion or device failure recorded in the Danish ICD Registry was the endpoint. The four-year survival rate for devices in the Danish Registry study was 81.1% for Medtronic and 95.7% for Boston Scientific (P<0.01).
