Abstract: A percutaneous catheter system for use within the human body and an ablation catheter for ablating a selected tissue region within the body of a subject. The percutaneous catheter system can include two catheters that are operatively coupled to one another by magnetic coupling through a tissue structure. The ablation catheter can include electrodes positioned within a central portion. The ablation catheter is positioned such that the central portion of a flexible shaft at least partially surrounds the selected tissue region. Each electrode of the ablation catheter can be activated independently to apply ablative energy to the selected tissue region. The ablation catheter can employ high impedance structures to change the current density at specific points. Methods of puncturing through a tissue structure using the percutaneous catheter system are disclosed. Also disclosed are methods for ablating a selected tissue region using the ablation catheter.

Abstract: This invention provides an device for electrical stimulation of the spinal cord. The device has an electrode assembly with a sufficiently thin profile to be implanted between the pial surface of the spinal cord and the dura mater, and secured to the dura. Electrodes on the electrode assembly are directed towards the surface of the spinal cord, and connected through the dura to a signal generator located outside the dura. Following implantation, the subject is treated by transmitting electrical signals from the signal generator through the leads to the electrodes, stimulating the subject's spinal cord.

Abstract: A method for imaging a lung of a patient is provided. The method includes acquiring a full inspiration computed tomography (CT) scan of the lung to provide a total lung capacity (TLC) image and acquiring a functional residual capacity contrast enhanced multi-energy CT scan of the lung. The method further includes processing the functional residual capacity contrast enhanced multi-energy CT scan of the lung to generate a perfused blood volume (PBV) image and a virtual non-contrast (VNC) image. The method further includes registering the TLC image to at least one of the PBV and VNC images so as to provide a map of regional ventilation and to co-register local ventilation with blood perfusion, generating a lung performance metric using the co-registered images, and outputting the lung performance metric at a user interface of a computing device.

Abstract: A method for visualization of dynamic objects using a generative manifold includes steps of: acquiring a set of measurements associated with the dynamic objects using sensors; estimating parameters of a generator using the set of measurements and estimating latent variables using the set of measurements; modeling using a computing device the dynamic objects as a smooth non-linear function of the latent variables using the generator such that points in a latent subspace are mapped to a manifold in a generative manifold model; and generating a visualization of the dynamic objects using the generative manifold model. The set of measurements may include multi-slice data. The generative manifold model may provide for modeling deformations.

Abstract: A prevention and safety management system utilizes a non-intrusive imaging sensor (e.g. surveillance cameras, smartphone cameras) and a computer vision system to record videos of workers not wearing sensors. The videos are analyzed using a deep machine learning algorithm to detect kinematic activities (set of predetermined body joint positions and angles) of the workers and recognizing various physical activities (walk/posture, lift, push, pull, reach, force, repetition, duration etc.). The measured kinematic variables are then parsed into metrics relevant to workplace ergonomics, such as number of repetitions, total distance travelled, range of motion, and the proportion of time in different posture categories. The information gathered by this system is fed into an ergonomic assessment system and is used to automatically populate exposure assessment tools and create risk assessments.
