S-ICD™ System

Subcutaneous Implantable Defibrillator

Protection Without Touching the Heart

The S-ICD System is the world's first and only subcutaneous implantable defibrillator that provides protection from sudden cardiac arrest (SCA) while leaving the heart and vasculature untouched.

Clinical Information

Two important clinical studies have been instrumental in demonstrating the S-ICD System as a compelling solution for the treatment of sudden cardiac arrest in a broad range of patients.

The US Investigational Device Exemption (IDE) study was completed in 2011 and was the cornerstone for US FDA approval. The objective of this study was to evaluate the safety and effectiveness in the treatment of life-threatening ventricular arrhythmias. This study was published in 2013 in Circulation.

Learn more from Dr. Martin Burke below on the published data.  

The EFFORTLESS Registry is an ongoing registry in Europe and New Zealand aimed at demonstrating the early, mid-term, and long-term clinical outcome and cost effectiveness of the S-ICD System. An interim analysis was published in the European Heart Journal in early 2014.
