Polyurethane Pacemaker Leadsperformance of marketed products may be misleading if not done appropriately. Clinically based postmarket surveillance can reveal the true actuarial survival of a device and the clinical mode of failure. Analysis of returned products may be required to understand the details of failure mechanisms ..
