Systems and methods are presented for monitoring brain pulsatility. A change in volume of the brain is estimated based at least in part on an output of a non-contact, surface measuring sensor (e.g., a distance sensor or a camera). A metric indicative of brain pulsatility is then calculated based at least in part on a ratio of the estimated change in volume of the brain relative to a change in arterial blood pressure.

Pulsatility measurement and monitoring

A apparatus and a method are disclosed for transmitting a signal directed to a blood vessel via a Doppler ultrasound waveform apparatus, receiving, by the Doppler ultrasound waveform apparatus, a reflected signal from the blood vessel; and determining, by a processing device, whether the blood vessel is an artery or a vein based on a blood flow velocity in the blood vessel.

Method and apparatus for locating and distinguishing blood vessel

A distractor and measuring device includes a first handle operatively connected to a first paddle and a second handle operatively connected to a second paddle. The first and second handles are pivotally connected to one another such that movement of the handles relative to one another causes the paddles to move relative to each other. At least one transducer is positioned on at least one of the first and second handles for measuring an amount of force applied during distraction. A measurement rod is pivotally connected to the device and is movable in a longitudinal direction relative to the first and second paddles. A potentiometer is operatively connected to the measurement rod to measure the angular orientation of the measurement rod.

An expandable intervertebral fusion cage that includes an inferior baseplate and a superior baseplate, an insert rotatably received between the inferior and superior baseplates, and a guide pin coupled to the inferior and superior baseplates for facilitating the rotation of the insert. The insert includes a pair of protuberances, each of which are releasably engageable with a corresponding lock groove formed within the inferior and superior baseplates. When said insert is rotated relative to the guide pin, the protuberances engage the lock grooves, and the inferior and superior baseplates expand from a collapsed position, in which said inferior and superior baseplates are juxtaposed with one another, and an expanded position, in which said inferior and superior baseplates are diverged away from one another. Tabs formed on the superior baseplate continuously engage slots formed within the inferior baseplate when the baseplates expand from their collapsed position to their expanded position.

In a method of electrical impedance tomography (EIT), a mediating fluid provides electrical contact between the electrodes of an EIT device and the skin of a body part to be examined. The height of the fluid is raised or lowered between impedance measurements, enabling tomographic images of the tissue under examination to be resolved mathematically for subsequent viewing. Tomographic planes are isolated by calculating differences between Cartesian models generated from impedance values measured at the plane of interest and at an adjacent plane.
