    摘要： An inflatable balloon cuff may be adapted to seal a patient's trachea via a mucoadhesive coating when associated with an endotracheal tube. The mucoadhesive seal may enhance a cuffs mechanical pressure seal, or may be used to seal the trachea at very low cuff inflation pressures. Also provided are inflatable balloon cuffs that include agents that may promote tracheal tissue growth and/or regeneration.

    摘要： The current techniques provide a system for monitoring a physiological parameter of a patient using microneedles that are coupled to an optical system, allowing spectroscopic measurements to be made immediately below the outer layer of the epidermis. In embodiments of the present invention, the results of the spectroscopic measurements are used to control the administration of a drug through an intravenous tube. In other embodiments, the microneedles may be coated with a drug for administration to the patient. In other embodiments, the microneedles may be mounted in a probe, wherein an actuator is used to move the needles into contact with the skin, and a drug delivery system is used to infuse the drug into the patient. A method for making needles is also provided.

    摘要： Embodiments of the present invention relate to a system and method for monitoring intracranial pressure. Embodiments of the present invention include emitting an electromagnetic wavelength into forehead tissue of a patient and detecting characteristics of the electromagnetic wavelength after the electromagnetic wavelength has been scattered by the tissue. The characteristics may include variations in the electromagnetic wavelength corresponding to a pulse. Further, embodiments of the present invention include analyzing the variations to identify venous pulsations, and determining whether intracranial pressure is elevated in the patient based on a correlation between the venous pulsations and levels of intracranial pressure.
