  • Patent number: 11648398
    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 an efficacy map comprising a plurality of voxels that are each assigned a value. In some examples, the efficacy map is selected from a plurality of stored efficacy maps based on a patient condition, one or more patient symptoms, or both the patient condition and one or more patient symptoms. In addition, in some examples, voxels of the efficacy map are assigned respective values that are associated with a clinical rating scale.

  • Publication number: 20230001183
    Abstract: A medical device for electrical stimulation therapy including an implantable lead with multiple levels of lead electrodes in a first segmented electrode configuration, at least one level of the lead electrodes comprising segmented electrodes. A flexible member is configured to be disposed over the first electrode segmented electrode configuration, the flexible member having a first inner side and a first set of member electrodes, at least some of the first set of member electrodes configured to be positioned to electrically contact corresponding lead electrodes of the first segmented electrode configuration. The flexible member having a second outer side and a second set of member electrodes in a second segmented electrode configuration which is different than the first segmented electrode configuration, at least some of the second set of member electrodes electrically coupled to corresponding member electrodes of the first set of member electrodes.

  • Patent number: 11369801
    Abstract: Devices, systems, and techniques are described for use in recharging a power source of a cranially mounted implantable medical device. In one example, a wearable medical device includes a flexible body configured to cover at least a portion of a scalp of a head of a patient. A securing member is connected to the flexible body and configured to extend around a circumference of the head to stabilize the flexible body with respect to the scalp of the patient. A fixation member is configured to mount to a location of the flexible body and couple the flexible body to a recharge coil that is configured to recharge the power source of the cranially-mountable implantable medical device.

  • Patent number: 10130282
    Abstract: Verification that an implantable medical system within a patient is MRI safe is provided. Several verifications may be performed such as verifying that the device and leads are of an MRI safe type, that the leads have adequate electrical integrity, that the device has entered an MRI safe mode, that the lead routing and device placement are MRI safe, and that the MRI settings of the MRI machine are safe for the implantable medical system. The result of these verifications may lead to a conclusion that the implantable medical system of interest is or is not MRI safe for a given MRI scan. An indication of this result may be output such as via a display so that an MRI technician can have some assurance as to whether to conduct the MRI scan.

  • Patent number: 9067076
    Abstract: The disclosure describes a method and system that allows a user to manage multiple groups of stimulation programs that provide stimulation therapy. A physician may prepare a plurality of programs, arranged in groups that each focus on one area, that the patient may evaluate in an effort to determine if any programs provide efficacious therapy. Since the patient may be evaluating many groups by using a patient programmer, managing the groups may be difficult. The patient programmer may enable the patient to hide ineffective groups to minimize the number of groups available for therapy. In addition, the programmer may allow the patient to mark each group or program as effective or ineffective, to more easily manage groups and programs during stimulation therapy. In addition, the patient may unhide a group or program if the patient desires to reevaluate a formerly hidden option.

  • Patent number: 8175720
    Abstract: Patient efficacy inputs are received over a period of time during which posture-responsive therapy is delivered to the patient while the patient occupies a plurality of posture states. The patient inputs are correlated with the times at which the inputs were received, a sensed posture state of the patient, and a therapy program defining therapy delivery at each of the times the posture state was sensed. Posture-responsive therapy is adjusted based on the historical posture-responsive therapy information correlating the patient input, patient input time, sensed posture state, and therapy program.
