Techniques related to classifying a posture state of a living body are disclosed. One aspect relates to sensing at least one signal indicative of a posture state of a living body. Posture state detection logic classifies the living body as being in a posture state based on the at least one signal, wherein this classification may take into account at least one of posture and activity state of the living body. The posture state detection logic further determines whether the living body is classified in the posture state for at least a predetermined period of time. Response logic is described that initiates a response as a result of the body being classified in the posture state only after the living body has maintained the classified posture state for at least the predetermined period of time. This response may involve a change in therapy, such as neurostimulation therapy, that is delivered to the living body.

Posture state responsive therapy delivery using dwell times

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 a memory that stores posture state definitions, a posture state module that records a plurality of postures of a patient over a period of time, and a processor that identifies a set of the plurality of postures that fall within a posture state, and redefines a boundary of the posture state based on where the postures fall within the posture state.

Posture state redefinition based on posture data

This disclosure describes techniques for generation of sleep quality information based on posture state data. The techniques may include obtaining posture state data sensed by a medical device for a patient, generating sleep quality information based on lying posture state changes indicated by the posture state data, and presenting the sleep quality information to a user via a user interface.

Generation of sleep quality information based on posture state data

In one aspect, a programmer for an implantable medical device comprises a user interface that receives user input corresponding to one or more selected stimulation therapy parameters for delivering stimulation therapy to a patient with the implantable medical device and presents an energy consumption estimate of a power source based on the selected stimulation therapy parameters; and a processor that determines one or more programming options that, if selected, would alter the selected stimulation therapy parameters and reduce the energy consumption estimate. The user interface presents at least one of the programming options to reduce the energy consumption estimate to the user with an indication that user selection of one or more of the presented programming options would alter the selected stimulation therapy parameters to reduce energy consumption of the implantable medical device.

User interface for optimizing energy management in a neurostimulation system

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.

Therapy system including multiple posture sensors

The disclosure provides a system that displays graphical representations of posture zones associated with posture states of a patient, on a display device communicatively coupled to a medical device. The medical device is configured to deliver therapy to the patient based on detected posture states of the patient, where the detected posture state is based on the posture zones. The display device may allow a user to manipulate the graphical representations of the posture zones, including changing the size of the posture zones. Additionally, the display device may allow a user to change transition times associated with transitions between posture states, and displaying an indication of the changed transition time by highlighting the two graphical representations of the posture zones corresponding to the posture states associated with the changed transition time.

Graphical manipulation of posture zones for posture-responsive therapy

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 a user interface that receives user input linking a plurality of posture states of a patient, and selecting a set of therapy parameter values for delivery of therapy to the patient for each of a linked posture states, a processor that defines the therapy to be delivered to the patient for each of the linked posture states based on the selection, and an implantable medical device that delivers the therapy to the patient for each of the linked posture states based on the selection.

Linking posture states for posture responsive therapy

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.

Programming posture responsive therapy

This disclosure is related to techniques for presenting therapy factors related to medical device therapy in a manner that allows a user, such as a patient or a clinician, to receive, comprehend and evaluate information relating to therapy delivered by the medical device efficiently. In one aspect, a method comprises obtaining a data set corresponding to a therapy factor associated with delivery of a medical therapy to a patient with a medical system including an implantable medical device, receiving a user selection associated with a subset of the data set, the subset of the data set including less than all the information relating to the therapy factor in the data set, and presenting a representation, corresponding to the subset of the data set, of the therapy factor on a display of a programmer.

Presentation of information associated with medical device therapy

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 of the patient 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.

Automated calibration of posture state classification for a medical device

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 a memory that stores a set of pre-established posture state definitions for delivery of posture state-responsive therapy to a patient, an external programmer comprising a user interface that receives a request from a user to update the set of pre-established posture state definitions, and a processor that updates the set of pre-established posture state definitions in response to the request.
