Abstract
A system (110, 150) for targeting a landmark (114, 160) is disclosed. The system includes an instrumented medical implant (112, 152), a control circuit (118, 153), a power supply (120, 157), and a landmark identifier (122, 154). The instrumented medical implant (112, 152) has one or more landmarks (114, 160) and each landmark (114, 160) has a corresponding coil (116, 162). The control circuit (118, 153) is electrically connected to the corresponding coil (116, 162), and the power supply (120, 157) is electrically connected to the control circuit (118,153). The landmark identifier (122, 154) has a magnetic sensor (124, 155) for sensing the corresponding coil (116, 162).
