Publication number: 20210204853Abstract: A system for diagnosing a mental health condition. The system comprises a smart device and a device including a memory and a processor. The smart device allows a participant to perform a cognitive task and the device receives data collected from the smart device in connection with the cognitive task performed by the participant. The device determines whether the participant has the mental health condition based on the data collected and via a classification algorithm or an artificial intelligence approach. If the participant has the mental health condition, the device determines whether the participant will respond to medication for treating the mental health condition via the classification algorithm or the artificial intelligence approach.Type: ApplicationFiled: May 17, 2019Publication date: July 8, 2021Applicant: Rutgers, The State University of New JerseyInventor: Mohammad Herzallah

Publication number: 20210204854Abstract: An intravascular catheter for nerve activity ablation and/or sensing includes one or more needles advanced through supported guide tubes (needle guiding elements) which expand to contact the interior surface of the wall of the renal artery or other vessel of a human body allowing the needles to be advanced though the vessel wall into the extra-luminal tissue including the media, adventitia and periadvential space. The catheter also includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened needles are advanced to penetrate into the vessel wall. Electrodes near the distal ends of the needles allow sensing of nerve activity before and after attempted renal denervation. In a combination embodiment ablative energy or fluid is delivered from the needles in or near the adventitia to ablate nerves outside of the media while sparing nerves within the media.Type: ApplicationFiled: December 18, 2020Publication date: July 8, 2021Inventors: David R. Fischell, Tim A. Fischell, Vartan Ghazarossian, Steven Almany, Michael Sasha John

Publication number: 20210204856Abstract: Mechanisms are provided to implement an automated echocardiograph measurement extraction system. The automated echocardiograph measurement extraction system receives medical imaging data comprising one or more medical images and inputs the one or more medical images into a deep learning network. The deep learning network automatically processes the one or more medical images to generate an extracted echocardiograph measurement vector output comprising one or more values for echocardiograph measurements extracted from the one or more medical images. The deep learning network outputs the extracted echocardiograph measurement vector output to a medical image viewer.Type: ApplicationFiled: March 18, 2021Publication date: July 8, 2021Inventors: Ehsan Dehghan Marvast, Allen Lu, Tanveer F.
