Abstract: An occlusion assembly for occluding the aorta of a patient is presented. The occlusion assembly includes an elongate shaft of two separate extrusions to which an elastomeric balloon envelope is bonded to an end of each. A support wire extends through the elongates shaft and the balloon envelope. At a distal end of the shaft, the support wire is provided with an atraumatic J-tip. At the proximal end of the shaft the proximal end of the support wire is secured to a proximal hub to give the entire assembly sufficient stiffness to be advanced into the vasculature of the patient. The balloon envelope is pre-molded to have a reverse teardrop or “ice cream cone” like shape and will maintain that general shape throughout inflation to the fully inflated state. If the balloon envelope is over inflated, the balloon envelope will advance distally and proximally (lengthening) along the support wire without damage to the surrounding vessel.

Abstract: An occlusion assembly and its uses in a REBOA procedure is disclosed. The occlusion assembly includes a single elongate shaft having an inflatable balloon, a proximal neck portion, a distal neck portion. The shaft defines a single lumen through which a wire is positioned for support of the shaft and through which an inflation fluid is also passed to inflate the balloon.

Abstract: An intraoperative imaging system combines a gamma probe and an ultrasound probe. The probes are linked to provide co-registration of gamma radiation detected by the gamma probe with an image acquired by the ultrasound probe. The gamma probe has a converging collimator made of a metal block having a plurality of channels therein, which converge from an output face toward an input face. Each channel extends between and opens out at the faces such that openings at the input face have smaller cross-sectional areas than openings at the output face so that each channel tapers inwardly from the output face to the input face. The collimator has an external focal point distant from the input face. The system improves identification and localization of cancerous cells, facilitating more accurate biopsy data and more complete surgical resection. The gamma probe increases sensitivity, while maintaining spatial resolution, and increasing depth of view.

Abstract: Exemplary pixel structures may include a pixel structure of a display device panel stack. The structures may include a first panel. The first panel may include a plurality of ultraviolet light sources disposed on a backplane. The structures may also include a second panel. The second panel may be coupled with the first panel. The second panel may have an inner surface facing the ultraviolet light sources. The second panel may include a transparent substrate and a down-conversion layer. The down-conversion layer may be disposed overlying the transparent substrate. The down-conversion layer may be configured to down-convert ultraviolet light into visible light. The plurality of ultraviolet light sources and the inner surface of the second panel may be separated by a distance of at least 2 ?m.

Abstract: A bone cement mold for a bone cement spacer, the bone cement mold including: a first mold component defining a first cavity shaped to form at least a majority of a head portion of the spacer; a second mold component defining a second cavity shaped to form a first part of a stem portion of the spacer; a third mold component defining a third cavity shaped to form a second part of the stem portion of the spacer; the second mold component and the third mold component combining to define a cavity shaped to form at least a majority of the stem portion; an abutting combination of the first mold component, second mold component, and third component defining a communicative cavity shaped to form the head portion integrally connected with the stem portion. Bone cement spacers formed from the bone cement mold, and computer methods and systems for selecting and operating the bone cement mold are also described.
