MEDICAL IMPLANT WITH INTEGRITY TESTING

摘要

Disclosed is a system and method of testing a medical implant implanted in a user. The system applies an electrical current to the user as a test signal, and measures the resulting signal as a measurement signal. The measurement signal may be used to determine a status of the medical implant. The test signal may be applied to the user via the medical implant itself and measured by a pair of externally- applied electrodes connected to an external part of the implant system, or may be applied by the pair of externally-applied electrodes by the external part of the implant system and measured by the medical implant. In one form, the medical implant system is a cochlear implant system.
