Abstract
Systems, methods, and devices include a cranial pressure monitoring system (CPMS) with a sensor delivery system. The CPMS includes internal monitoring system to detect changes in intracranial pressure either acutely or chronically over time. The system is insertable through the nasal cavity to place a pressure monitor, such as an impedance monitoring device, (e.g., and/or other sensor(s)) in the region of the cribriform plate and/or the nasal concha (superior). As such, brain measurements can be taken through the thin bone material of the cribriform plate using non-invasive techniques.
Claims20
A brain measurement and analysis device including:
- a tube with a side opening a predetermined distance from:
- an end of the tube;
- or
- an intermediate location on the tube;
- a balloon at least partially positionable within the tube at the side opening and including one or more sensors, the balloon being configured to:
- expand out of the side opening as part of a sensor placement procedure;
- and
- retract into the side opening as part of a sensor withdrawal procedure;
- and
- a cord coupled to the balloon and passing at least partially through an inner channel of the tube.
A brain measurement system including:
- a nasogastric tube with a side opening;
- one or more visual indicators disposed on the nasogastric tube a predetermined distance from the side opening;
- a balloon having one or more sensors embedded into a material forming the balloon, the balloon being expandable out the side opening to place the one or more sensors at a target location, and at least partially retractable back into the side opening;
- one or more sensors disposed on a sensor balloon, the sensor balloon being positionable within the nasogastric tube and configured to:
- expand out of the side opening as part of a sensor placement procedure;
- and
- retract into the side opening as part of a sensor withdrawal procedure.
A method of brain measurement, the method including:
- inserting a nasogastric tube, including a side opening, into a nasal passageway of a patient, the nasogastric tube at least partially containing a balloon;
- causing the balloon to expand out of the side opening and into a target area adjacent to a cribriform plate or a superior nasal concha, such that one or more sensors disposed on the balloon are delivered to the target area;
- and
- collecting sensor data related to brain activity or brain pressure from the one or more sensors.
