First Claim
Patent Images
1. A minimally invasive method for monitoring a patient who has a neurological or psychiatric condition, the method comprising:
- sampling brain activity signals with the one or more implanted devices that are positioned between at least one layer of scalp and the skull of the patient;
wirelessly transmitting a data signal that is encoded with data indicative of the sampled brain activity signals from the one or more implanted devices to an external device;
processing the data signal in a processing assembly of the external device to estimate the patient'"'"'s propensity for a neurological event; and
generating an output in response to the processing of the data signal.

Abstract
The present invention provides systems and methods for ambulatory, long term monitoring of a physiological signal from a patient. At least a portion of the systems of the present invention may be implanted within the patient in a minimally invasive manner. In preferred embodiments, brain activity signals are sampled from the patient with an externally powered leadless implanted device and are transmitted to a handheld patient communication device for processing to estimate the patient'"'"'s propensity for a seizure.

12. A minimally invasive method of monitoring a patient'"'"'s propensity for a neurological event, the method comprising:
-
transmitting a signal from an external device that is configured to interrogate and provide power to one or more implanted devices that are positioned in between one or more layers of the patient'"'"'s scalp and skull;
wirelessly receiving a data signal from the one or more implanted devices that is encoded with data indicative of sampled brain activity signals, wherein the received data signal is derived from the transmitted signal from the external device;
processing the data signal in a processing assembly of the external device to provide a real-time estimate of the patient'"'"'s propensity for the neurological event; and
generating an output communication to the patient that provides an indication of the patient'"'"'s propensity for the neurological event. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A minimally invasive method of monitoring a patient'"'"'s EEG signals for use in monitoring a patient'"'"'s propensity for a neurological event, the method comprising:
-
receiving a substantially continuous interrogation signal in an implanted device that is positioned between at least one layer of the patient'"'"'s scalp and skull from a device external to the patient'"'"'s body;
in response to the interrogation signal, substantially continuously sampling an EEG signal from the patient;
substantially continuously transmitting a wireless data signal encoded with data that is indicative of the sampled EEG signal from the patient to the device external to the patient'"'"'s body, wherein the sampled EEG signal is processed in the external device to estimate the patient'"'"'s propensity for a neurological event. - View Dependent Claims (22, 23, 24, 25)
