Publication number: 20240017075Abstract: 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.Type: ApplicationFiled: July 12, 2023Publication date: January 18, 2024Inventors: Hyun-Joo Park, Yagna Pathak

Publication number: 20230414288Abstract: 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.Type: ApplicationFiled: September 6, 2023Publication date: December 28, 2023Inventors: Yagna Pathak, Simeng Zhang, Dehan Zhu, Anahita Kyani, Hyun-Joo Park, Erika Ross

Publication number: 20230240760Abstract: The present disclosure provides systems and methods for estimating an orientation of an implanted deep brain stimulation (DBS) lead. Such methods include generating an initial image dataset, down-sampling a respective image or adding noise to images of the subset of the initial image dataset, and re-slicing at least a subset of the modified image dataset along an alternative primary imaging axis, to generate an integrated image dataset. The method also include partitioning the integrated image dataset into a preliminary training image dataset and a testing image dataset, and re-sizing at least a subset of the preliminary training image dataset with a localized field of view around a depicted DBS lead, to generate a training image dataset. The method further includes training a machine-learning model using the training image dataset, and executing the trained machine-learning model to estimate, during a DBS implantation procedure, an orientation of a subject implanted DBS lead.Type: ApplicationFiled: April 5, 2023Publication date: August 3, 2023Inventors: Yagna Pathak, Hyun-Joo Park, Simeng Zhang, Anahita Kyani, Erika Ross, Dehan Zhu, Douglas Lautner

Publication number: 20230218900Abstract: Devices and methods to effectuate closed loop electrical stimulation of nerve tissue, based on feedback data, to mitigate pain of a patient are disclosed. Feedback data corresponding to bioelectric signals of neurons stimulated by stimulation pulses may be received and analyzed. Based on receipt of the feedback data, it may be determined to modify one or more stimulation parameters, corresponding to the stimulation pulses, to enhance an efficacy of the stimulation pulses at blocking generation and/or propagation of one or more pain signals through a neuroanatomy of the patient. Subsequent and additional stimulation pulses may be provided based on a modified set of stimulation parameters and configured to enhance attenuation of generation and/or transmission of pain signals through the neuroanatomy of the patient to ultimately reduce a level of pain experienced by the patient.Type: ApplicationFiled: January 12, 2022Publication date: July 13, 2023Inventors: Hyun-Joo Park, Yagna Pathak, Hongxuan Zhang, Anahita Kyani, Erika Ross, Jeffrey Urbanski

Publication number: 20230100246Abstract: A system and method for modulating delivery of remote therapy to a patient having an implantable medical device (IMD). Upon establishing a remote care session between a patient controller device and a clinician programmer, wherein the clinician and the patient are remotely located with respect to each other, a determination may be made if a first triggering event is detected. Responsive to the determination, a remote therapy session used for programming the patient's IMD is paused and one or more remote care therapy setting controls provided at the clinician programmer device to facilitate one or more adjustments with respect to the patient's IMD are disabled. Subsequently, responsive to detecting a second triggering event, the remote therapy session with the patient may be resumed, wherein the one or more remote care therapy setting controls of the clinician programmer device are enabled.Type: ApplicationFiled: December 2, 2022Publication date: March 30, 2023Inventors: Scott DeBates, Douglas Alfred Lautner, Tucker Tomlinson, Andrew Csavoy, Yagna Pathak
