Abstract: An implantable medical device (IMD) configured for implant in a body includes an enclosure that houses communication circuitry, an antenna, a dielectric layer, and a transmission line. The enclosure includes an outer surface configured to be oriented in a direction facing the exterior of the body and to be placed adjacent tissue. The antenna includes a ground plane corresponding to the enclosure, a dielectric spacer that conforms to the outer surface of the enclosure, and a radiating element that conforms to the dielectric spacer. The dielectric layer overlays the radiating element and the dielectric spacer. The transmission line is electrically connected between the radiating element and the communication circuitry.

Abstract: Systems, methods and devices are disclosed for directing and focusing signals to the brain for neuromodulation and for directing and focusing signals or other energy from the brain for measurement, heat transfer and imaging. An aperture in the skull and/or a channel device implantable in the skull can be used to facilitate direction and focusing. Treatment and diagnosis of multiple neurological conditions may be facilitated with the disclosed systems, methods and devices.

Abstract: A flexible antenna is associated with an active implantable medical device to facilitate communication between the implantable medical device and an external component in the outside world via, for example, long range or far field telemetry. The flexibility of the antenna allows it to conform to the shape of the location at which it is situated, such as on the cranial bone of a patient for an antenna associated with a cranially implanted medical device. The conformability of the antenna helps to maintain the antenna in the desired shape and to maintain it in the desired location relative to implantable medical device and the patient and improves patient comfort.

Abstract: An external data retrieval apparatus receives a low resolution version of a physiological signal from an active implantable medical device and determines if the physiological signal represents a clinically significant event. The apparatus provides an indication of such determination to the implantable medical device. If the physiological signal does represent a clinically significant event, the apparatus receives a full download of the physiological signal from the implantable device.

Abstract: A system and method for estimating the current delivered to a patient during voltage-regulated electrical stimulation therapy by an implantable medical device includes calculating a total charge delivered and a peak current delivered and the time at which the peak current was delivered using a proxy for the current delivered to the patient and a component such as a current controlled oscillator, the output of which is proportional to the current proxy together with memory for storing values relating to the output proportional to the current proxy. The stored values also may be used to construct a waveform approximating the current delivered to the patient during a therapy of voltage-regulated stimulation. The system and method may be implemented in an active implantable medical device such as an implantable neurostimulator.

Abstract: A sensor of an implantable medical device senses electrical activity of the brain. A data analyzer of the device monitors an electrographic signal corresponding to the electrical activity of the sensed brain signal, and processes the brain signal to obtain a measure of phase-amplitude coupling. For a selected portion of the electrographic signal, the data analyzer detects first features and second features of the electrographic signal. The first features represent oscillations in a low frequency range, while the second features represent oscillations in a frequency range higher than the low frequency range. For example, the low frequency range may correspond to theta frequency and the higher frequency range may correspond to gamma frequency. The data analyzer determines a measure of phase-amplitude coupling between oscillations in the low frequency range and oscillations in the higher frequency range based on occurrences of second features which coincide with first features.
