  • Publication number: 20240017075
    Abstract: Devices and methods to effectuate waveform distortion adjusted stimulation therapy of tissue, based on an inverse model of the tissue, are disclosed. In some aspects a linear model of an electrode used to delivery therapy and of the tissue is determined. Parameter values of the linear model may be determined based on measuring voltage feedback during application of stimulation and/or measurement waveforms. The parameter values of the linear model of the electrode and tissue may be used to determine a forward model of the electrical response of the tissue. From the forward model, an inverse model of the tissue may be determined and the inverse model can be used to modify or filter a stimulation waveform to reduce waveform distortion caused by tissue, such as tissue primitive and/or tissue capacitance. Accordingly, providing therapy with the filtered waveform may have increased efficacy by accounting for and adjusting for waveform distortion.

  • Publication number: 20230414288
    Abstract: A system and method for facilitating DBS electrode trajectory planning using a machine learning (ML)-based feature identification scheme configured to identify and distinguish between various regions of interest (ROIs) and regions of avoidance (ROAs) in a patient's brain scan image. In one arrangement, standard orientation image slices as well as re-sliced images in non-standard orientations are provided in a labeled input dataset for training a CNN/ANN for distinguishing between ROIs and ROAs. Upon identification of the ROIs and ROAs in the patient's brain scan image, an optimal trajectory for implanting a DBS lead may be determined relative to a particular ROI while avoiding any ROAs.
