  • Patent number: 8352039
    Abstract: This disclosure describes techniques for programming stimulation therapy programs according to therapy targets (e.g., symptoms or areas of pain) in a patient to which they are applied. Several programs can be programmed for each therapy target, stored on an implantable medical device, and retrieved later by a programmer to modify, edit, delete, create, and/or select a therapy program for each of the therapy targets. Each therapy target is independent from the other therapy targets, and a user can select or change a program under one therapy target without affecting programs under the other therapy targets. During programming, a user can specify parameters for each program applicable to only that program, and can specify parameters for each therapy target applicable to every program associated with that therapy target. The organization of programs into slots and the selection of a program in each slot may be manual or automated.

  • Patent number: 8193766
    Abstract: System and method for estimating a time to recharge a rechargeable power source of an implantable medical device. A plurality of measured parameters relating to the implantable medical device and an external charging device are applied to a model of recharging performance and an estimate is provided to a patient, perhaps in advance of charging. Once charging has begun, updated estimates can be provided until charging is complete. Once charging is complete, the model may be updated to reflect any differences in the estimated time to complete charging and the actual time required to complete charging. The model may be based on limitations to the rate at which charge may be transferred to the rechargeable power source over a plurality of intervals.

  • Publication number: 20110172562
    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 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.
