  • Patent number: 9440084
    Abstract: A programming session for an implantable medical device that includes a posture responsive therapy mode includes at least two phases. In a first phase, a first set of therapy parameter values are modified while the posture responsive therapy mode is deactivated. In the posture responsive therapy mode, the medical device automatically selects one or more therapy parameter values that define therapy delivered to a patient based on a detected posture state. In a second phase, the posture responsive therapy mode is activated and a second set of therapy parameter values are adjusted after observing a patient response to the posture responsive therapy delivered with the first set of therapy parameter values selected during the first phase. The second set of therapy parameter values may, for example, define the patient posture states or the modification profiles with which the medical device adjusts therapy upon detecting a posture state transition.

  • Patent number: 9050471
    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: 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.

  • Patent number: 8401666
    Abstract: In general, the disclosure describes techniques for modifying therapy provided to a patient by a medical device. The techniques may be applicable to electrical stimulation therapy or other therapies. Modification of therapy may include adjustment of one or more therapy parameter values that define one or more characteristics of stimulation therapy delivered to a patient. The therapy modification may be based on activity of a patient that is detected by an IMD, such as a change in a detected posture state occupied by the patient. Different therapy modifications may be applied for different changes in detected posture state. An IMD may modify therapy based on a transition from one posture state to another posture state, and apply different modifications for different transitions. In some aspects, the modification may include a profile, such as a ramp up or ramp down in a parameter value over a period of time. The profile may be different for different posture transitions.
