Abstract: The pumping of arterial blood into the cerebral spinal fluid (CSF) of a patient's brain creates cycle pressure undulations in the CSF and the brain itself. Brain injuries can create abnormal changes in this pressure waveform. Accordingly, the disclosed technology includes an ultrasound based device for monitoring this brain movement in the CSF (“pulsatility”) to diagnose and monitor brain injury.

Abstract: The disclosed devices and methods cool the nasal and/or oral cavity and perioral area, which in turn triggers a positive sensory reflex response to the brain leading to improvement of abnormally regulated cerebral vasomotor (brain arterial) tone which is thought to be the primary trigger factor for migraine headaches. Cooling is applied temporarily (10 to 30 minutes) to the inside of either or both nostrils. In some examples, the device is a single-use cooling “bullet” made from plastic (or other materials), has a conical, egg, nasal, oval, or other suitable shape and fits tightly to the inside of either nostril. The bullet may contain a nontoxic coolant (i.e., propylene glycol), water or other coolant which is kept at a cold state (e.g. 3-6 degrees Celsius below normal body temperature).

Abstract: The disclosed systems and methods provide a simple, safe, effective and widely applicable method to clean the inside of an endotracheal tube. For instance, disclosed is an endotracheal suction catheter that includes a brush-suction segment that allows the catheter to mechanically brush off secretions on the inner surface of an endotracheal tube (“ETT/TT”) while simultaneously suctioning the debris.

Abstract: The disclosed device, method, and system provide a simple, safe, effective and widely applicable method-device to suction the throat in patients with absence or incompetent swallowing reflexes. For instance, disclosed is a combination enteric feeding and pharyngeal suctioning tube that both pumps food to a patient's stomach while suctioning a patient's throat to remove pharyngeal secretions. The suctioning tube may be an attachment to a feeding tube that terminates just at or above the esophageal opening when connected to the feeding tube. The end of the pharyngeal suctioning tube may include perforations that allow the pharyngeal secretions to be vacuumed into the suctioning portion for removal.

Abstract: Apparatuses, systems, methods, and computer code for, among other things, monitoring the health of samples such as the brain while providing local cooling or heating. A representative device is a heat transfer probe, which includes an inner channel, a tip, a concentric outer channel, a first temperature sensor, and a second temperature sensor. The inner channel is configured to transport working fluid from an inner inlet to an inner outlet. The tip is configured to receive at least a portion of the working fluid from the inner outlet. The concentric outer channel is configured to transport the working fluid from the inner outlet to an outer outlet. The first temperature sensor is coupled to the tip, and the second temperature sensor spaced apart from the first temperature sensor.
