  • Publication number: 20190336751
    Abstract: The disclosure is directed to programming implantable stimulators to deliver stimulation energy via one or more implantable leads having complex electrode array geometries. The disclosure also contemplates guided programming to select electrode combinations and parameter values to support efficacy. The techniques may be applied to a programming interface associated with a clinician programmer, a patient programmer, or both. A user interface permits a user to view electrodes from different perspectives relative to the lead. For example, the user interface provides a side view of a lead and a cross-sectional view of the lead. The user interface may include an axial control medium to select and/or view electrodes at different axial positions along the length of a lead, and a rotational control medium to select and/or view electrodes at different angular positions around a circumference of the lead.

  • Publication number: 20190111266
    Abstract: In some examples, a processor of a system evaluates a therapy program based on a score determined based on a volume of tissue expected to be activated (“VTA”) by therapy delivery according to the therapy program. The score may be determined using a three-dimensional (3D) grid comprising a plurality of voxels that are each assigned a value. The processor may register the VTA with the 3D grid and determine the score for the therapy program based on the values assigned to voxels with which the VTA overlaps. One or more therapy programs for electrical stimulation therapy (e.g., deep brain stimulation) may be selected based on the scores determined based on the 3D grid.

  • Patent number: 10165977
    Abstract: Therapy delivery to a patient may be controlled based on a determined sleep stage of the patient. In examples, the sleep stage may be determined based on a frequency characteristic of a biosignal indicative of brain activity of the patient. A frequency characteristic may include, for example, a power level within one or more frequency bands of the biosignal, a ratio of the power level in two or more frequency bands, or a pattern in the power level of one or more frequency bands over time. A therapy program may be selected or modified based on the sleep stage determination. Therapy may be delivered during the sleep stage according to the selected or modified therapy program. In some examples, therapy delivery may be controlled after making separate determinations of a sleep stage based on the biosignal and another physiological parameter, and confirming that the sleep stage determinations are consistent.

  • Patent number: 9814885
    Abstract: One or more stimulation electrodes may be selected based on a bioelectrical signal sensed in a brain of a patient with a sense electrode combination that comprises at least one electrode and a physiological model that indicates one or more anatomical structures of the brain of the patient that are proximate the implanted at least one electrode. In some examples, the bioelectrical brain signal indicates which electrodes are located closest to a target tissue site. The physiological model can be generated based on a location of implanted at least one electrode within a patient and patient anatomy data, which can, for example, indicate one or more characteristics of patient tissue proximate to the implanted at least one electrode. In some example, the physiological model includes a therapy field model that represents a region of the tissue of the patient to which therapy is delivered via a selected set of electrodes.

  • Patent number: 9789302
    Abstract: A physiological signal of a patient is sensed with sense electrodes symmetrically arranged relative to a stimulation electrode. In some examples, a member includes a plurality of relatively small electrodes that are configured to function as both sense and stimulation electrodes. One or more of the electrodes may be selected as stimulation electrodes and two or more different electrodes of the member may be selected as sense electrodes that are symmetrically arranged relative to the one or more selected stimulation electrodes. In some examples, a member includes a plurality of levels of segmented sense electrodes and a plurality of levels of stimulation electrodes. The levels of sense electrodes are arranged such that each level of stimulation electrodes is adjacent at least two levels of sense electrodes symmetrically arranged relative to the level of stimulation electrodes.

  • Publication number: 20170259064
    Abstract: In some examples, a system may include a plurality of electrodes, electrical stimulation circuitry, and a controller. The controller may be configured to select one or more parameters of therapy to be delivered to a brain of a patient and to control the electrical stimulation circuitry to deliver the therapy to the brain of the patient based on the selected parameters and via a first one or more electrodes of the plurality of electrodes. The parameters may be defined based on a first plurality of electrical signals sensed at a plurality of different positions within the brain of the patient when electrical stimulation is not delivered at each of the positions and a second plurality of electrical signals sensed at each of the plurality of different positions within the brain of the patient in response to electrical stimulation delivered at each of the positions at a plurality of different intensities.

  • Patent number: 9724521
    Abstract: In some examples, one or more processors determine characteristics of frequency components of a sensed bioelectrical signal. In response to determining the characteristics, the one or more processors determine therapy parameters for frequency components of a stimulation signal. The one or more processors may determine the therapy parameters based on the characteristics of the frequency components of the sensed bioelectrical signal. As another example, the one or more processors may determine the therapy parameters based on received information after the characteristics of the frequency components of the sensed bioelectrical signal are displayed to a user.
