Attorney, Agent or FirmInternational ClassA61N 001/00AbstractA body function assistance device, capable of analyzing changing but cyclic physiologic needs of a patient and generating a response based on the analysis. A microprocessor in the body function assistance device controls the response of the device to various external events and internal timer events. The microprocessor recognized variations in patterns of recurrent events and adjusts the output of the body function assistance device in response to the detected variations. In a particular embodiment, an implantable cardiac pacer is responsive to a circadian wake-sleep cycle. | |
