Abstract: A sampling tool for isolating and collecting a tissue biopsy includes a hollow sampling cylinder that includes a first end and an opposing second end. The first end being a sharpened, annular cutting edge and a central bore extending completely from the first end to the second end. The sampling tool also includes a plunger having a first end and a second end. The plunger includes an air evacuation feature in the form of an air evacuation channel that extends from one end of the plunger to the other end and is open at both ends. The sampling tool has particular utility in isolating and collecting cylindrical core placental biopsies of a standardized size that can be used for multiple downstream applications, including the sampling of other harvested solid, soft-tissue organs such as brain, liver, kidney, and spleen.

Abstract: The Invention comprises a body, an actuator pivotally connected to the body, and a retractable needle adapted to provide fluid communication between a patient and a fluid collection tube, typically a blood collection tube, attachable to the device. A significant feature of the subject device is a retraction cavity disposed inside the actuator that is manually positionable to receive a portion of the needle retraction assembly following removal of the blood collection tube. Retraction is initiated by depressing the forwardly extending end of the actuator relative to the body, thereby causing a retainer clip to release the needle holder, after which the needle holder and a part of the needle are propelled into the retraction cavity by expansion of a compressed spring. The needle is thereby withdrawn from the patient and into the housing, reducing the likelihood of accidental needle sticks and preventing reuse of the device.

Abstract: A system and method for personal fatigue risk management, performed using a smartwatch including a digital processor, associated memory, and an accelerometer for measuring acceleration in X, Y, and Z axes. A signal is received from the accelerometer indicating a movement of the smartwatch, and the value of the signal is stored in association with indicia of the time at which the signal was received in a time-stamped bin. The stored movement values are analyzed using a state algorithm to determine sleep, wake, and off-wrist state values. Fatigue risk values are determined from the sleep and wake state values, using a state algorithm. The probable relative risk of errors and incidents as compared to average risk, for the wearer of the watch, are then calculated. A warning is issued when the fatigue risk data indicates that one of the thresholds has been exceeded.

Abstract: A method, apparatus and probe for examining tissue for the presence of target cells, particularly cancerous cells, by subjecting the tissue to be examined to a contrast agent containing small particles of a physical element conjugated with a biological carrier selectively bindable to the target cells. Energy pulses are applied to the examined tissue. The changes in impedance and/or optical characteristics of the examined tissue produced by the applied energy pulses are detected and utilized for determining the presence of the target cells in the examined tissue. In a described preferred embodiment, the applied energy pulses include laser pulses, and the physical element conjugated with a biological carrier is a light-sensitive semiconductor having an impedance which substantially decreases in the presence of light. The same probe used for detecting the targeted cells may also be used for destroying the cells so targeted.
