Abstract: Long-term electrocardiographic and physiological monitoring over a period lasting up to several years in duration can be provided through a continuously-recording insertable cardiac monitor. The sensing circuitry and the physical layout of the electrodes are specifically optimized to capture electrical signals from the propagation of low amplitude, relatively low frequency content cardiac action potentials, particularly the P-waves that are generated during atrial activation and storing samples of captured signals. In general, the ICM is intended to be implanted centrally and positioned axially and either over the sternum or slightly to either the left or right of the sternal midline in the parasternal region of the chest.

Abstract: A data collection system collects and stores physiological data from an ambulatory patient at a high resolution and/or a high data rate (“more detailed data”) and sends a low-resolution and/or downsampled version of the data (“less detailed data”) to a remote server via a wireless network. The server automatically analyzes the less detailed data to detect an anomaly, such as an arrhythmia. A two-tiered analysis scheme is used, where the first tier is more sensitive and less specific than the second tier. If the more sensitive analysis detects or suspects the anomaly, the server signals the data collector to send more detailed data that corresponds to a time period associated with the anomaly. The more specific second tier analyses the more detailed data to verify the anomaly. The server may also store the received data and make it available to a user, such as via a graphical or tabular display.

Abstract: Cochlear implant systems can comprise an implantable subsystem comprising a cochlear electrode, a stimulator, a battery, and a first near field communication interface positioned subcutaneously proximate an ear canal. Cochlear implant systems can further comprise a removable earplug comprising a sensor, a second near field communication interface, and a signal processor. The removable earplug can be inserted into an ear canal to align the first and second near field communication interfaces. Once aligned, the battery can provide electrical power to the removable earplug via the near field communication interfaces. The signal processor can receive input signals from the sensor of the removable earplug and generate a stimulation signal representative of the auditory signals. The signal processor can communicate the stimulation signal to the stimulator via the near field communication interfaces.

Abstract: Electrical non-invasive brain stimulation (NIBS) delivers weak electrical currents to the brain via electrodes that are affixed to the scalp. NIBS can excite or inhibit the brain in areas that are impacted by that electrical current during and for a short time following stimulation. Electrical NIBS can be used to change brain structure in terms of increasing white matter integrity as measured by diffusion tensor imaging. Together the electrical NIBS can induce changes in brain structure and function. The present methods and devices are adaptable to and configurable for facilitating the enhancement of brain performance, and the treatment of neurological diseases and tissues. The present methods and devices are advantageously designed to utilize modern electrodes deployed with, inter alia, various spatial arrangements, polarities, and current strengths to target brain areas or networks to thereby enhance performance or deliver therapeutic interventions.

Abstract: An implantable medical device (IMD) is described capable of determining whether a patient is susceptible to freezing of gait events during ambulatory movement without the patient demonstrating an episode of freezing of gait. In one example, the IMD senses, via one or more electrodes, a bioelectrical signal of a brain of the patient while the patient performs movement associated with freezing of gait. The IMD determines, based on the bioelectrical signal, whether the patient is susceptible to freezing of gait while the patient is not experiencing an episode of freezing of gait. Further, upon detecting the movement associated with freezing of gait, the IMD delivers electrical stimulation therapy to the patient configured to suppress freezing of gait.
