  • Patent number: 10118041
    Abstract: Techniques for performing lead functionality tests, e.g., lead impedance tests, for implantable electrical leads are described. In some of the described embodiments, an implantable medical device determines whether a patient is in a target activity state, e.g., an activity state in which lead impedance testing will be unobtrusive, such as when a patient is asleep, or capture information of particular interest, such as when the patient is active, in a particular posture, or changing postures. The implantable medical device performs the lead functionality test based on this determination. Additionally, in some embodiments, the implantable medical device may group a plurality of measurements for a single lead functionality test into a plurality of sessions, and perform the measurement sessions interleaved with delivery of therapeutic stimulation.

  • Patent number: 9259587
    Abstract: The disclosure is directed to techniques for shifting between two electrode combinations. An amplitude of a first electrode combination is incrementally decreased while an amplitude of a second, or subsequent, electrode combination is concurrently incrementally increased. Alternatively, an amplitude of the first electrode combination is maintained at a target amplitude level while the amplitude of the second electrode combination is incrementally increased. The stimulation pulses of the electrode combinations are delivered to the patient interleaved in time. In this manner, the invention provides for a smooth, gradual shift from a first electrode combination to a second electrode combination, allowing the patient to maintain a continual perception of stimulation. The shifting techniques described herein may be used during programming to shift between different electrode combinations to find an efficacious electrode combination.

  • Patent number: 9186517
    Abstract: A programmer allows a clinician to identify combinations of electrodes from within an electrode set implanted in a patient that enable delivery of desirable neurostimulation therapy by an implantable medical device. The programmer executes an electrode combination search algorithm to select combinations of electrodes to test in a non-random order. According to algorithms consistent with the invention, the programmer may first identify a position of a first cathode for subsequent combinations, and then select electrodes from the set to test with the first cathode as anodes or additional cathodes based on the proximity of the electrodes to the first cathode. The programmer may store information for each combination tested, and the information may facilitate the identification of desirable electrode combinations by the clinician. The clinician may create neurostimulation therapy programs that include identified desirable program combinations.

  • Patent number: 8843203
    Abstract: An implantable medical device delivers neurostimulation therapy to a patient according to a parameter set. A parameter set may consist of a number of programs that are delivered substantially simultaneously. When programming the implantable medical device for the patient, a clinician programmer may maintain a session log for the patient that includes a listing of programs delivered to the patient and rating information provided by a clinician and the patient for programs of the list. The listing may be ordered according to the rating information in order to facilitate the selection of programs for a parameter set. A program library that may include particularly effective programs organized according to a directory structure may be stored in a memory. One or both of the implantable medical device and a patient programmer may store usage information that provides an objective assessment of therapy use by the patient, and allows a clinician to later improve the therapy based on the usage information.

  • Patent number: 8694115
    Abstract: A programming device used to program delivery of therapy to a patient by a medical device, such as an implantable neurostimulator or pump, maintains or accesses a programming history for the patient. The programming history may take the form of a record of programs, e.g., combinations of therapy parameters, tested during one or more prior programming sessions. The programming device may analyze, or otherwise use the programming history to provide guidance information to a user, such as a clinician, which may assist the user in more quickly identifying one or more desirable programs during a current programming session.
