EMBLEM™ S-ICD System

Subcutaneous Implantable Defibrillator

The Rationale

Protection Without Touching the Heart

For years, patients' lives have been extended by transvenous implantable cardiac defibrillators (TV-ICDs). These devices are truly life savers. Now, Boston Scientific has developed a unique solution, called the EMBLEM S-ICD System, which protects patients from sudden cardiac arrest (SCA), without touching the heart.

Evolving ICD Technologies, Leaving the Heart Untouched = Less Invasive

Implantable cardioverter-defibrillators (ICDs) save lives when used for the primary or secondary prevention of sudden cardiac arrest. Transvenous and epicardial systems are however associated with complications related to the difficulty of maintaining long-term lead integrity and vascular access.

Transvenous lead survival rate
The great variation observed in ICD lead survival is due to a variety of factors including variable study definitions of ICD lead malfunction, variable performance of different ICD lead models, and the impact of patient characteristics and physician implantation techniques on ICD lead performance.

Benefits of the EMBLEM S-ICD System

The EMBLEM S-ICD is the 2nd generation S-ICD (Subcutaneous Implantable Defibrillator) and incorporates Boston Scientific’s core competencies providing you with a 20% thinner device that is projected to last 40% longer than first generation.3,4 It is also enabled for LATITUDETM NXT Remote Patient Management.

Less Biomechanical Stress

Located outside of the heart and ribcage, the EMBLEM S-ICD subcutaneous electrode is exposed to significantly less biomechanical stress than traditional transvenous leads:

Unique Construction

The subcutaneous electrode is uniquely designed to minimize the risk of insulation abrasion/breach and conductor fractures: 

Multistrand cable-core design provides exceptional strength

The results of selected studies of ICD lead performance are shown. To be included, studies had to (1) be published in a peer-reviewed journal after 1999, (2) provide follow-up for at least 18 months after implantation, and (3) statistically account for patients who had died or were lost to follow-up. The data point represents the point estimate of the study for ICD lead survival. The size of the data point is proportional to the total number of patients in the study. The white data point represents the study by Eckstein et al, published in the current issue of Circulation.
