Abstract: An outer sheath used with a surgical access assembly is disclosed. The outer sheath includes a proximal end, a distal end and a body portion therebetween. The proximal end defines a first opening. The distal end is disposed opposite the proximal end and defines a second opening. The body portion includes at least one slot formed therein. At least one light source is retained within the slot, adjacent the proximal end.

Abstract: Screen material with improved visibility for use as an insect screen. The screen material is formed of a mesh of polymer coated threads having a denier of 190 to 360, wherein the polymer coated threads comprise 20-30 wt. % polyester thread core and 70-80 wt. % PVC coating.

Abstract: Screen material with improved visibility for use as an insect screen. The screen material is formed of a web of polymer coated threads having a denier of 190 to 360, wherein the polymer coated threads comprise 20-30 wt. % polyester thread core and 70-80 wt. % PVC coating.

Abstract: There is provided a test method for visual characteristics which is less load to a subject and enables testing of visual characteristics of the subject, a test image set for testing visual characteristics, a determining method for determining characteristics of correction filter based on a test result of visual characteristics, and a correction filter made based on it. The test image set includes multiple test images. Each of the multiple test images has a background area and a test area located in the background area. The multiple test images are provided with figures having colors different from a color of the background area in at least one of R, G, or B components in a RGB color space, and the multiple test images are different from each other in colors of at least one of the background area or the test area.

Abstract: A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

Abstract: An illumination light adjusting system according to the present disclosures includes a color vision characteristics storage configured to store color vision characteristics of a user, and a wavelength characteristics changing unit configured to change wavelength characteristics of illumination light based on the color vision characteristics stored in the color vision characteristics storage.

Abstract: A tissue cutting device is disclosed and described. The device includes a handpiece and an outer cannula in which a reciprocating inner cannula is disposed. A delivery sleeve may be selectively provided that is configured to be disposed about the outer cannula for delivery of a variety of devices.

Abstract: The disclosure provides for an oral composition, the oral composition including at least one active agent, at least one filler component, and water in an amount sufficient such that the oral composition has a total moisture content of about 15% to about 30% by weight or greater based on the total weight of the oral composition.

Abstract: A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described, as well as alternative systems for tissue preservation and transport. The cutting device includes an outer cannula in which a reciprocating inner cannula is disposed. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. A temperature control sleeve may be disposed around the tissue collector to control the temperature of the tissue samples. A preservation system may be supplied that is configured to deliver fluids to tissue samples in the tissue collector. A fluid supply sleeve may be disposed about the outer cannula and is selectively positionable along the length of the outer cannula.

Abstract: A method for testing visual characteristics includes a providing step of providing a subject with a test image and a changing step of changing an optical element to be placed between the subject and the test image. The test image includes a first image area containing a color to which rod cells are sensitive, and the first image area is placed in such a manner that light coming from the first image area forms an image on a region outside a central fovea of a retina when the subject is looking at a center of the test image. The optical element set includes a plurality of first optical elements configured to transmit light of a first wavelength band to which the rod cells are sensitive within a visible light band. An optical element that the subject does not feel dazzled by the test image is specified.
