An Ultra Low Power Active Medical Implant (ULP-AMI) is a medical implant with an integrated medical implant communication system (MICS). An ULP-AMI is used in all kinds of medical implants, such as pacemakers, implantable defibrillators, nerve stimulators, and other types of implanted devices. The ULP-AMI uses transceiver modules for radiofrequency communication between an external device referred to as a programmer/controller and a medical implant placed within a human or animal body.
These communication systems are used in many ways, for example: device parameter adjustment (e.g. modification of the pacing parameters), transmission of stored information (e.g. electrocardiograms stored over time or recorded during a medical event), and the real time transmission of monitored vital life signs for short periods.
ULP-AMI equipment is used only under the direction of a physician or other duly authorized medical professional. The duration of these links is limited to the short periods of time necessary for data retrieval and reprogramming of the medical implant.
