Abstract
Variety of long-term implantable medical devices have been developed and accumulated date is desired to improve the long-term result and to get to know the cause of failure. For those purpose, planning a registry system on long-term implantable medical device is important. The purpose, choice of the device to start with, the location of registry center, space, man power and funding are major factors that we had to talk about. United Kingdom has nation wide medical device registry systems including in heart valve, breast implant, pace maker, cephalic shunt tube and implantable pump. And also it has one regional joint registry system. There are two explant analysis studies in heart valve and knee joint. Three national and one regional registry centers, and two explant systems were visited and studied. The importance and possibility of the systems in Japan were discussed. It is possible to start registry of medical device, however, we have to know it is strongly desired in Japan and Japanese government is willing to give funding
