Sorin Group has announced the Japanese approval and the market release of ISOLINETM1, its latest generation of defibrillation leads. Leads are insulated wires inserted through the vein as part of an implantable cardioverter defibrillator (ICD) or a pacemaker system. Connecting the device to the heart, the leads carry high voltage and electrical impulses from the implanted device to the heart when needed by the patient. ISOLINETM defibrillation leads have a multi-lumen structure with a silicone body and include an ETFE protective coating placed around the cables leading to the electrodes.
