Devices and methods for monitoring physiological information relating to sleep with an implantable device

摘要

Described here are implantable devices and methods for monitoring physiological information relating to sleep. The implantable devices are generally designed to include at least one sensor for sensing physiological information, a processor for processing the physiological information using low computational power to detect a sleep stage, and a battery. The detected sleep stage information may then be used to indicate sleep quality, identify or monitor a medical condition, or guide treatment thereof.

1. A method of detecting a sleep state or sleep stage by analyzing electrical signals from a patient's brain with an implantable device, the method comprising:
sensing electrical signals on a plurality of sensing channels; applying a first sensing channel of the plurality of sensing channels to a first detection channel, the first detection channel configured to determine whether at least one analysis of the electrical signals sensed on the first sensing channel results in an affirmative outcome; applying a second sensing channel of the plurality of sensing channels to a second detection channel, the second detection channel configured to determine whether at least one analysis of the electrical signals sensed on the second sensing channel results in an affirmative outcome; and applying the result of the at least one analysis of the first detection channel and the result of the at least one analysis of the second detection channel to a logic operation, wherein an output of the logic operation indicates whether a sleep state or sleep stage has been detected by the implantable device.
