Sudden Cardiac Arrest (SCA) is a life-threating heart condition. It is also one of the most common causes of death in developed countries claiming more than 350,000 lives per year in Europe. There are currently two different implantable technologies to prevent SCAs. The first one is Transvenous Implantable Cardioverter-Defibrillators (T-ICDs), which are implanted with wires that snake through veins into the heart. The second one is Subcutaneous Implantable Cardioverter-Defibrillators (S-ICD), which also have generators and leads but avoid direct access to the heart. However, these solutions pose many drawbacks such as major complications to the vascular system, replacement needs, aesthetical and comfort impacts, complex implantation procedures and cyber-security issues.


The ISSD introduces a new dimension in subcutaneous ICDs. It is a totally integrated device fully implanted in the body, with no leads within the heart and no generators. Thus, it leaves the vascular system untouched. It is a wireless rechargeable device, halving replacement rates when compared to current technologies. The device is almost invisible and improves patients comfort. It is designed from a cyber-security point of view and can be implanted in a rapid procedure (20 min on average).
