  • Publication number: 20140046399
    Abstract: An implantable neurostimulator system for treating movement disorders includes a sensor, a detection subsystem capable of identifying episodes of a movement disorder by analyzing a signal received from the sensor, and a therapy subsystem capable of supplying therapeutic electrical stimulation to treat the movement disorder. The system treats movement disorders by detecting physiological conditions characteristic of an episode of symptoms of the movement disorder and selectively initiating therapy when such conditions are detected.

  • Patent number: 8423145
    Abstract: An implantable neurostimulator system adapted to provide therapy for various neurological disorders is capable of varying therapy delivery strategies based on the context, physiological or otherwise, into which the therapy is to be delivered. Responsive and scheduled therapies can be varied depending on various sensor measurements, calculations, inferences, and device states (including elapsed times and times of day) to deliver an appropriate course of therapy under the circumstances.

  • Patent number: 8423156
    Abstract: Medical electrical lead systems and related methods are described. The lead systems may be configured to be at least partially implanted in neural tissue of a subject, such as a brain of a subject. Some variations of the lead systems may comprise a lead body, an electrode connected to the lead body, and a bioactive agent. The electrode and/or lead body may comprise a substrate, and the bioactive agent may be supported by the substrate (e.g., by a substantial portion of the area of the substrate). Methods described herein may comprise contacting the substrate of a lead body and/or an electrode of a medical electrical lead system with at least one bioactive agent, where the lead body and the electrode are connected to each other.

  • Patent number: 8140152
    Abstract: Described here are intracranial ferrules, systems, and methods for sensing and stimulating neural tissues. The ferrules are generally designed to include a holding area for retaining an implantable device. In some variations, the ferrule itself may perform the sensing and stimulating functions. In other variations, the ferrule may function to sense data from neural tissues and the implantable device may function to stimulate neural tissues. In yet other variations, the ferrule may function to stimulate, and the implantable device may function to sense data from, the neural tissues. The sensing and stimulating functions may be used to detect and/or treat various neurological conditions.

  • Publication number: 20100331717
    Abstract: A system and method for detecting and predicting neurological events with an implantable device uses a relatively low-power central processing unit in connection with signal processing circuitry to identify features (including half waves) and calculate window-based characteristics (including line lengths and areas under the curve of the waveform) in an electrographic signal received from a patient's brain. The features and window-based characteristics are combinable in various ways according to the invention to detect and predict neurological events in real time, enabling responsive action by the implantable device.
