The present invention discloses a novel, user-wearable system for monitoring the oxygen concentration, or oxygenation trend, in the tissue of a subject undergoing aerobic stress. The system comprises a lightweight detector, worn against the skin surface of the subject, at the site being monitored. The system further includes wearable power pack and display means for displaying information indicative of the metabolic condition of the region being monitored. The detector preferably employs a continuous wave spectrophotometer having one or more sources of electromagnetic radiation with wavelengths between about 760 and 800 nanometers directed into the tissue of the subject. The detector utilizes photon migration to detect the portion of the transmitted radiation arriving at an adjacent skin region. The present invention also discloses methods for displaying the aerobic metabolic condition of a subject.

Apparatus and method for selectively engaging and securing an array of shelf dividers to a mounting device which is securable to a display shelf. In the first form a divider is characterized by a divider structure having an elongated vertical wall and elongated horizontal base that operates to divide, organize and support the displayed merchandise. A resilient latch located on the underside of the base of the divider structure selectively engages and secures the divider structure onto a mounting device comprising a receiving member running longitudinally along the length of the surface of the mounting device which is securable along the front edge of a display shelf. The latch and the receiving member each comprise reciprocating (i.e. complementary) protrusions to allow the cooperative engagement of the divider structure and mounting device, thus locking the divider member to and unlocking the divider member from the mounting device to permit the repositioning of the display as desired without necessitating removal of the merchandise from the display. In addition when the divider structure and mounting device are fully engaged, a second protrusion on the underside of the divider member cooperates with a flange or lip on the mounting device to prevent lateral movement of the divider structure and maintain the position of the divider perpendicular to the mounting device and the front edge of the shelf. In a second embodiment, the divider structure comprises a pusher track and a spring urged pusher assembly to automatically push merchandise to the front of the shelf. Another embodiment comprises a divider base without a vertical divider wall, and with or without a pusher track and spring urged pusher assembly, thus pushers and dividers can be used in various convenient combinations within a shelf management system.

An intravascular stent assembly for implantation in a body vessel, such as a coronary artery, includes undulating circumferential rings having peaks on the proximal end and valleys on the distal end.

A light output arrangement is provided and may be used as a backlight for a display. The arrangement comprises a bendable light-outputting layer (51), for example, comprising a light-guide, and a bendable light-directing layer (50), for example, comprising a lens array. The layers (50, 51) are fixed together so as to prevent relative lateral movement at the mid-points but otherwise are constrained to bend in conformance with each other. The light-directing layer comprises a plurality of structures, such as lenses (81), which cooperate with, for example, light extraction features (80) in the light guide (51) so as to direct light output from the light-directing layer (50) in substantially the same direction (82, 83) irrespective of bending of the layers (50, 51).

Devices and methods are provided for reducing the lateral displacement of an endovascular device, e.g. a stent graft, within an aneurysm sac. A stabilization system comprising one or more stabilizing elements is inserted within the aneurysm space between an implanted device and the vessel wall. Filling this space prevents changes in curvature of the implanted endovascular device, and prevents longitudinal displacement, thereby providing for improved long-term stability and durability of endovascular repair.

A chamber has a lid that permits opening and closing of the chamber for inserting or removing a cell culture from the chamber while the chamber is in a stack of chambers without removing any of the chambers from the stack. The lid of the chamber may have one or more ports which enable substances to be introduced into or removed from the chamber when the chamber is sealed by the lid. In one embodiment, the lid is a side wall of a rectangular chamber in a stack of rectangular chambers. Spacers may be provided between the chambers of the stack to provide space between the chambers and restrict horizontal movement of the chambers relative to each other. A flexible container containing an atmosphere may be connected to a port of the chamber, and the atmosphere may be transferred to the chamber by compressing the flexible container. After a cell culture is introduced into the chamber, the stack of chambers may be placed into an incubator. The chamber is suitable for exposing a cell culture in the chamber to volatile and potentially hazardous chemicals to test for the effect of the chemicals on the cell culture.

One embodiment of techniques for confocal microscopy includes illuminating a spot on a surface of a biological sample. A first emission intensity from the spot is detected in a first range of optical properties; and a second emission intensity in a second range. A pixel that corresponds to the spot is colored using a linear combination of the first and second emission intensities. Sometimes, the pixel is colored to approximate a color produced by histology. In some embodiments, a surface of a sample is contacted with a solution of acridine orange. Then, a spot is illuminated with a laser beam of wavelength about 488 nanometers (nm). Fluorescence emission intensity is detected above about 500 nm. Sometimes, a certain illumination correction is applied. In some embodiments, a sample holder that compresses a sample is removable from a stage that is fixed with respect to a focal plane of the microscope.
