  • Patent number: 9149210
    Abstract: Techniques relate to operating a medical device by classifying a detected posture state of a patient. This classification may be performed by comparing the detected posture state to posture state definitions available within the system. Each definition may be described in terms of a parameter (e.g., vector) indicative of a direction in three-dimensional space. The posture state definitions may be calibrated by automatically estimating values for these parameters, thereby eliminating the need for the patient to assume each posture state during the calibration process to capture actual parameter values. According to another aspect, the estimated parameter values may be updated as the patient assumes various postures during a daily routine. For instance, estimated vectors initially used to calibrate the posture state definitions may be changed over time to more closely represent posture states the patient actually assumes, and to further adapt to changes in a patient's condition.

  • Publication number: 20150256680
    Abstract: The embodiments described herein recite a telephone communication system used for handling information such as messages, typically voice mail messages, and, more particularly, is directed to a system that provides distributed session initiation protocol (SIP) silos. Distributed SIP silos (DSS) is a Communications Application Platform (CAP) feature that maintains the site's call capacity even when a signaling server fails. DSS uses multiple non-redundant signaling servers to provide SIP signaling for the same set of media ports. Because there are multiple signaling servers providing signaling for the same set of ports, the failure of one signaling server only terminates the calls it was actively processing and once those calls have been cleaned up, all the available (non-suspended) ports in the configuration are available to the remaining signaling servers.

  • Publication number: 20150238693
    Abstract: The disclosure provides a system that displays a posture state indication to a user. A posture state indication represents the current posture state of the patient, which may be a combination of patient posture and activity. As a patient changes posture and activity throughout a daily routine, a posture state detector may generate a posture state value that may be used to categorize the patient's posture or posture and activity level as one of multiple posture states used to adjust therapy. The posture state may be associated with one of multiple posture state indications that may be presented to the patient. The posture state indication shows the patient the posture state currently detected by the posture state detector. The posture state indication may help the patient to effectively monitor therapy changes due to automatic, semi-automatic or patient-directed therapy adjustments made as a function of posture state.

  • Patent number: 9026223
    Abstract: Posture-responsive therapy is delivered by the medical system based on posture state input from only one of multiple posture sensors at any given time. An example implantable medical system includes a first posture sensor and a second sensor. A processor controls therapy delivery to the patient based on at least one of a patient posture state or a patient activity level determined based on input from only one of the first or second posture sensors. In some examples, one of multiple posture sensors of an implantable posture-responsive medical system is used to automatically reorient another posture sensor (of the system), which has become disoriented. The disoriented posture sensor may be automatically reoriented for one or more posture states at a time.

  • Patent number: 8905948
    Abstract: The disclosure describes techniques for generation of proportional posture information over multiple time intervals. The techniques may include obtaining posture state data sensed by a medical device for a patient during delivery of therapy by the medical device, determining durations for which the patient occupied each of a plurality of posture states based on the posture state data, generating proportional posture information for a plurality of different time intervals based on the durations, wherein the proportional posture information for each of the time intervals indicates proportional amounts of the respective time interval in which the patient occupied the posture states, and presenting the proportional posture information to a user via a user interface.

  • Patent number: 8798759
    Abstract: The disclosure is directed to a user interface with a menu that facilitates stimulation therapy programming. The user interface displays a representation of the electrical leads implanted in the patient and at least one menu with icons that the user can use to adjust the stimulation therapy. The user may drag one or more field shapes from a field shape selection menu onto the desired location relative to the electrical leads. A manipulation tool menu may also allow the user to adjust the field shapes placed on the electrical leads, which represent the stimulation region. The programmer that includes the user interface then generates electrical stimulation parameter values for the stimulator to deliver stimulation according to the field shapes or field shape groups defined/located by the user. The field shapes may represent different types of stimulation representations, such as current density, activation functions, and neuron models.

    Abstract: The disclosure is directed towards posture-responsive therapy. To avoid interruptions in effective therapy, an implantable medical device may include a posture state module that detects the posture state of the patient and automatically adjusts therapy parameter values according to the detected posture state. A system may include an implantable medical device that delivers therapy to a patient according to a set of therapy parameter values while the patient occupies a first posture state, a user interface that receives patient input associating one or more of the therapy parameter values with a second posture state different from the first posture state, and a processor that automatically defines therapy for delivery to the patient when the patient occupies the second posture state based on the associated therapy parameter values.

  • Patent number: 8751010
    Abstract: A system and method for determining, during a recharge session, an amount of time until a subsequent recharge session is required to charge a rechargeable power source of an implantable medical device. A model allows a determination of the time until recharge without suspending charging during the recharge session by basing the determination on an initial measured battery voltage and a present current into the rechargeable power source. Alternatively, charging is suspended during the recharge session, and voltage measurements are taken, after which time charging is resumed, without patient input or suspending the recharge session.

  • Patent number: 8744591
    Abstract: This disclosure describes techniques for obtaining an image of an anatomical implant region where leads associated with an implantable medical device are implanted in a patient, manipulating the image to show lead locations and placements, performing necessary image compression and manipulations, adjusting the image to associate it with information (e.g., patient, metadata, annotations, etc.) useful to a subsequent programmer retrieving the image, and transferring a copy of the captured image to the implantable medical device. The image stored in the implantable medical device may be retrieved at a later time by a user of programmer, where the user can use the image and other associated information to program subsequent therapy.

  • Publication number: 20140081354
    Abstract: This disclosure describes techniques for combining an image of a region defined by the user to receive stimulation therapy with an image of representation of leads which will deliver the therapy to the defined region, and importing the combined image on an implantable medical device connected to the leads that will deliver the stimulation therapy. During the process of combining the images, the user manipulates one or both of the images to combine the image such that the leads are placed for accurate therapy delivery. In some examples where more than one region is to receive stimulation therapy, each region can have a different image and/or a different set of leads associated therewith, and a combined image of each region may be produced, manipulated, and imported on the implantable medical device.
