This article is to discuss the distributing model and tracing model of such devices in post market surveillance，as well as the importance of correct identity recording of patients and implantable medical devices in medical institutions；and provide the solutions for how to use the information means in the traceability system，establish a unique device identification （UDI） for implantable device based on the GS1 product coding standard，define the minimum information in tracing process，and establish a central database to support automatic reading of the tracing information，as well as the supervision of tracing information，etc.
