Engineered to provide lifelong protection, the Ilesto 5 Series system from BIOTRONIK is small in size, lets ICD and CRT-D patients safely undergo magnetic resonance imaging (MRI) exams, and uses the most cutting-edge technology. It features ShockReduct™ technology that limits the amount of inappropriate shocks with the unique home monitoring system from BIOTRONIK. ICD and CRT-D engineering is perfected with this system, and the BIOTRONIC SmartScale™ is both long-lasting and small in size. Engineered as one of the smallest CRT-D and ICD series available today, this system is compact but does not sacrifice quality or longevity. It has a header size that is reduced and includes a DF4 connector, and provides a better battery shape and technology.
