Patent CA-2469001-A1 (CA)
Title: Bioabsorbable sealant
Inventor: AHARI FREDERICK
IPC: A61B17/08
Filed: 2002-12-06
Abstract: Openings in a mammalian body made by any medical procedure or non-medical event are sealed with a bioabsorbable plug or sewn with a bioabsorbable suture. In one exemplary embodiment, the plug in dehydrated, unexpanded condition is pushed by a pushing device through the lumen of a needle until a first part of the plug is external to the opening and a second part is internal to the opening. The needle is then withdrawn while the position of the pushing device is maintained. The pushing device is then withdrawn, leaving the plug in sealing relation to the opening. The body's moisture causes the plug to expand to complete the sealing of the opening, or the expansion may be caused by exposure to air, light, or other stimulant. The opening may be formed in soft tissue, internal organs, or hard tissue. The plug seals the flow of liquid or gaseous biological fluids.

Title: Selective focus system for use in photography
Inventor: HYLEN STEVEN H L
IPC: G03B3/10
Filed: 2002-12-09
Abstract: An optical system is provided for allowing regional focus control. The system uses a variable power optical component system as two optical shear plates (22, 24) that can be laterally displaced with respect to each other to adjust and alter the field curvature of the optical system. This changing of the field curvature creates an area of focus whose particular size and shape within the field of view is controlled through manipulation of the shear plates (22, 24) with respect to each other and the field of view. The area of focus can be repositioned to any point within the field of view so that the area of focus can affect the image light coinciding with that particular region. The shear plates (22, 24) are preferably positioned at the intermediate focal plane of the optical system, between the camera body (12) and the taking lens (16). The image which has been altered, by the shear plates (22, 24) is then transposed to the camera body (12) by a relay lens (14) and recorded by film at the primary film plane (28) located within the camera body (12). The end result is a optical system that is suitable for a camera wherein regional focus control is achieved, regardless of the depth of field of the camera taking lens (16) or its aperture settings.

Des colonies obtenues expriment le gène marqueur en l'absence d'un mésappariement et n'ont pas d'expression en présence d'un mésappariement. La détection MRD est capable de détecter un mésappariement unique dans 10 kb d'ADN. De plus, la détection MRD peut analyser plusieurs fragments de manière simultanée, mettant en place un procédé efficace de génotypage et de détection de mutation à rendement élevé.

Title: Nose pad assembly for an eyeglass frame
Inventor: NEGISHI TOHRU
IPC: G02C5/12
Filed: 2004-09-07
Abstract: A nose pad assembly is slidably mounted to an eyeglass frame by which a pair of multifocal lenses are held. The nose pad assembly includes a pair of oval nose pads within which elongated guide grooves are defined. Two pairs of upper and lower magnets are coaxially and fixedly mounted in the upper and lower ends of the respective nose pads. A pair of slides are slidably moved along the guide grooves and attached to a pair of pad arms of the eyeglass frame. The slides include a corresponding pair of slide magnets positioned within the respective guide grooves.      The slide magnets are selectively attracted to the upper and lower magnets to hold the eyeglass frame in its upper and lower positions, respectively. A bridge member extends between the upper end of the nose pads. The bridge member is configured to resist a substantially vertical force which may be applied thereto when the eyeglass frame is moved between its upper and lower positions. The bridge member is free to flex in a substantially horizontal direction so that orientation of the nose pads can readily be adjusted.

Inventor: MILLER ROBERT A III
IPC: D04B1/22
Filed: 2004-12-24
Abstract: A knitted fabric comprising two confronting webs, each web being formed by a series of continuous lengths of yarn extending generally parallel to one another and having loops arranged in walewise and coursewise rows. One web overlies the other and, the two webs being united at intervals by a tuck stitch of yarn of one web engaging the other web. The tuck stitches are spaced apart walewise by a plurality of courses to create channels between the stitches. The channels extend walewise of the webs. At least one yarn is inserted under tension between the two fronting webs and held in parallel relation to the parallel lengths of yarn. When relaxed, the yarn inserted under tension causes the confronting webs to be spaced apart within each of the channels.

Title: Procede ameliore d'identification de molecules de ciblage
Inventor: FAN XIAO-MIN
IPC: A61K49/00
Filed: 2003-08-08
Abstract: L'invention concerne des procédés permettant de valider la spécificité de ciblage in vivo de composés en fonction de critères pharmacocinétiques. L'invention propose un procédé amélioré conçu pour produire une banque de peptides qui présentent une complexité réduite et une appartenance augmentée à une composé candidat, ce procédé consistant à exprimer des peptides cycliques codant des oligonucléotides qui comprennent des séquences de codage randomisées représentant des acides aminés qui ne forment pas de liaison. L'invention concerne également la détermination des relations structure-activité au moyen d'une technique cinétique mettant en oeuvre une méthode d'adhérence sur plastique in vivo. La conception de composés de ciblage présentant des conformations d'espace/de charge/d'hydrophobicité appropriées peut être fondée sur les résultats de ces déterminations de relations structure-activité cinétiques (kSAR). L'invention concerne en outre des compositions obtenues à partir de cette méthodologie, qui sont utiles dans le traitement de troubles neuroinflammatoires et de troubles du poumon, ainsi que de troubles qui impliquent des interactions de coagulation sanguine disséminée avec l'endothélium vasculaire.

IPC: C12Q1/68
Filed: 2002-12-10
Abstract: L'invention concerne un procédé et un appareil permettant de laver un substrat solide à l'aide d'une onde ultrasonore après une réaction d'hybridation. Ledit procédé consiste 1) à placer le substrat solide dans un récipient contenant une solution de lavage dans laquelle une réaction d'hybridation été exécutée; 2) à utiliser un générateur ultrasonore pour produire une certaine intensité d'onde ultrasonore et à la transmettre dans la solution de lavage; (3) à laver le substrat à l'aide de l'effet de cavitation produit dans la solution ultrasonore par l'onde ultrasonore. Du fait que les bulles de cavitation de la solution de lavage peuvent produire un écoulement intense et un microécoulement local de filet d'eau contre la surface solide, réduire de manière évidente la tension et la friction de la surface du liquide et améliorer l'écoulement de liquide, un adsorbât et un dépôt non spécifiques faiblement fixés peuvent être rapidement éliminés par lavage.

Patent CA-2508185-A1 (CA)
Inventor: KETTELL ALFRED E
IPC: B65D65/34
Filed: 2005-05-25
Abstract: A novel package wrapper made of plastic film with a line of package-opening perforations through the film positioned in one face of the package and being overlaid by a piece of plastic tape which seals the perforations, the tape having a dry edge. The perforations and overlying tape are spaced inward from the edges of the package and extend substantially linearly, but have the tape ends terminate short of any package seal so that they are not bound into the seals. In one embodiment the package wrapper is made of air and moisture non-permeable shrink wrap film, and the tear down tape is made of a non-permeable non-shrink plastic which has been processed to exhibit the same shrink characteristics as those of the shrink wrap film, so that when the wrap film is shrunk during packaging the tape shrinks the same amount as the film and does not itself pucker or wrinkle the film. The package is completely sealed but does not require the use of any tool to open it. Package opening is accomplished by grasping the tape dry edge and pulling it toward the line of perforations. The tape peels from the wrapper film until it reaches the perforations, where continued pulling of the tape ruptures the film through the perforations and permits the film to be further torn to open the package.  Tapes with several variant configurations are disclosed. Apparatus and methods for making the novel package and wrapper are shown and described.
