Abstract: The present disclosure provides systems and methods related to electroencephalography (EEG) electrode arrays. In particular, the present disclosure provides systems and methods relating to the manufacture and use of high-resolution electrocorticography (ECOG) electrode arrays and stereoelectroencephalography (SEEG) electrode arrays having various combinations and arrangements of microelectrodes and macroelectrodes for recording and modulating nervous system activity.

Abstract: The present disclosure provides a wearable computing device including (i) one or more sensors, (ii) a partially or fully transparent display, and (iii) a control system. The control system is configured to receive data indicative of a three-dimensional model of a body part. The control system is further configured to receive sensor data from the one or more sensors. Based on the sensor data, the control system is further configured to determine a relative position of a physical body part of a physical body with respect to the wearable computing device. Based on the determined relative position, the control system is configured to cause the display to provide a hologram corresponding to at least a portion of the three-dimensional model of the body part such that the hologram appears overlaid onto at least a portion of the physical body part when viewed through the display.

Abstract: An occlusion-resistant catheter, occlusion-resistant catheter tip, and methods of use are disclosed. In one embodiment, the occlusion-resistant catheter includes a hollow cannula defining a fluid passageway therethrough, the hollow cannula having a body portion with a first end and a second end, and an occlusion-resistant tip positioned at the first end of the body portion. The occlusion-resistant tip has at least one port that provides access to an interior lumen, and the interior lumen is in fluid communication with the fluid passageway of the body portion.
