  • Publication number: 20200051738
    Abstract: Embodiments described herein comprise a current transformer having a primary winding with multiple primary parallel branches that divide the primary current, and a secondary winding which is placed in any one, or more, branches. The current thus divided in the primary branches produces an alternating magnetic flux which induces alternating current in the secondary winding for an end user application. The invention disclosed herein reduces the weight and size of the current transformer drastically compared to the existing conventional current transformers.

Transitions between anodic and cathodic modes of stimulation can include linear or user-customized adjustments of stimulation parameters of the anodic and cathodic modes during a transition period. Continuous interleaving of anodic and cathodic modes of stimulation can include repeating, continuous adjustments of stimulation parameters of the anodic and cathodic modes according to user-customized parameters and user-defined time apportionments. Interfaces additionally provide information regarding the relative energy usages of the different stimulation modes and visualizations of the effects of adjustments of the stimulation modes on energy usage.

  • Publication number: 20190099606
    Abstract: Implantable medical devices (IMD) such as those used in Deep Brain Stimulation application are commonly replaced when the device's useful life expires. At the time of replacement, the electrodes that were connected to the initial IMD are typically reused with the replacement IMD. It is desirable for the replacement IMD to utilize the stimulation parameters that were being utilized to provide stimulation in the initial IMD, but it is important that the electrodes be connected to the replacement IMD in a similar manner as they were connected to the initial IMD if stimulation parameters are reused. A connected electrode profile that includes measurements of electrical parameters associated with the electrodes can be generated in the initial IMD and the replacement IMD, and the profiles can be compared to determine whether the electrodes are connected in a similar manner in the replacement IMD as they were in the initial IMD.
