Patent CA-2424077-C (CA)
Title: Outil de depistage ultrasonique de tissu cellulaire
Inventor: KELLY KEVIN
IPC: A61B8/00
Filed: 2001-10-15
Granted: 2016-04-12
Abstract: L'invention concerne des diagnostics et des analyses ultrasoniques de tissu cellulaire. Une sonde ultrasonique se déplace sur le tissu cellulaire à une vitesse uniforme que l'on peut synchroniser avec la vitesse de capture d'image de l'analyseur ultrasonique afin de réaliser un ensemble complet et contigu d'images analysées du tissu. On peut maintenir la sonde dans une seule position lorsqu'on la déplace sur le tissu ou on peut la régler dynamiquement lors de l'analyse afin d'obtenir un contact optimal avec le tissu analysé. Les données d'image sont alors capturées et converties à un format qui peut se stocker facilement et qui est également compatible avec une visionneuse. Celle-ci permet de lire des images analysées de manière optimale pour le dépistage de cancers et d'autres anomalies. Une fonction de localisation permet à l'utilisateur de sélectionner un point présentant un intérêt sur une image individuelle analysée et de choisir un autre point de référence connu. La fonction calcule et donne la distance du point de référence au point présentant un intérêt en trois dimensions. Le système peut servir pour quasiment tous les types de tissu mais peut également être optimisé pour le dépistage de cancers du sein. On peut placer un élément de densité différente sur le mamelon afin de fournir un point de référence visible sur les images analysées. On peut recouvrir le sein d'un tissu composé de manière à maintenir le sein en place et réduire les erreurs d'analyse ultrasonique ainsi que le maintien de l'élément en place. La fonction de localisation susmentionnée se sert du mamelon comme d'un point de référence à partir duquel on peut mesurer tout cancer ou autre anomalie dépistés.

Patent CA-2460450-C (CA)
Inventor: BEISER LEO
IPC: G03B21/14
Filed: 1996-10-08
Granted: 2005-12-27
Abstract: Certain optical imaging systems exhibit disparate vertical and horizontal image focal surfaces; at least one of which is tipped with respect to the optical axis .      The projection optics which illuminates such systems must provide that the vertical image components focus upon the nominal vertical image surface, while the horizontal image components focus on the disparate horizontal image surface. Because at least one of these image surfaces may be tilted with respect to the projection axis, correction is required to maintain focus over the entire image surfaces and to eliminate keystoning. The system may also require differing vertical and horizontal image magnifications as projected upon the above disparate focal surfaces. This invention describes inter alia, the techniques for meeting these varied requirements; to project a rectilinear object field such that it forms a final focused rectilinear image in a system having tipped and disparate image planes.

Title: Ballonnet non flexible presentant une couche superieure flexible qui protege des endoprotheses a revetement lors de la dilatation
Inventor: WEBER JAN
IPC: A61F2/958
Filed: 2002-11-15
Granted: 2010-09-21
Abstract: L'objectif de la présente invention est de minimiser le potentiel d'endommagement de revêtements pour endoprothèse biocompatibles et/ou renfermant des médicaments. A cette fin, une gaine élastique flexible se trouve sur une couche entre un ballonnet de dilatation non flexible et une endoprothèse non dilatée, fixée au ballonnet au moyen d'une pince de fixation. L'ensemble de déploiement d'endoprothèse, monté sur une sonde, est manipulé dans le corps du patient jusqu'à un site de déploiement souhaité, puis est gonflé afin de dilater l'endoprothèse jusqu'au diamètre souhaité. Lors de la dilatation, le matériau élastique flexible entre l'endoprothèse et le ballonnet non flexible permet d'empêcher le ballonnet non flexible d'endommager le revêtement d'endoprothèse et d'empêcher des perforations induites par endoprothèse, par exemple, d'endommager le ballonnet non flexible. Le ballonnet de dilatation d'endoprothèse non flexible dégonflé et la gaine élastique flexible sont ensuite retirés du corps du patient, laissant l'endoprothèse déployée au niveau du site d'implantation souhaité, avec son revêtement sensiblement intact.

Abstract: In a method for joining at least two plate-shaped workpieces by a fastening tool and a device for operating the fastening tool, the fastening tool comprises a punch for exerting a punch force to perform a joining operation and a clamp for exerting a clamping force upon the workpieces at the joining area. During the joining operation the punch exerts a high punch force to perform the joining operation and the clamp exerts substantially no clamping force to allow for free material deformation in the joining area. After the joining operation both the punch and the clamp exert high forces at the same time to reduce any material deformations of the workpieces and to provide for compression of the workpieces in the joining area. Preferably the invention is used in a riveting tool for setting self piercing rivets; as an alternative it may be used in a clinching tool.

Abstract: A method of determining an amount of analyte in a sample solution is provided. The method involves the use of an assay device that has a substantially planar assay surface. The surface has a plurality of calibration dots a test dot printed thereon. The calibration dots contain pre-determined quantities of the analyte while the test dot includes a capture antibody for binding to the analyte. The analyte is mixed into a solution having a sample antibody for the analyte, where the antibody is labeled with a detectable marker. The sample solution is introduced into the loading portion of the assay device for delivery to said reading portion. The next step is to measure the intensity of detectable marker in the calibration dots. With the data obtained, one then prepares a calibration curve correlating the amount of analyte in said calibration dots to said intensity of detectable marker. The intensity of detectable marker in the test dot can be measures and the amount of anayte present in said test dot calculated by comparing the intensity of detectable marker to the amount of analyte corresponding to the intensity in said calibration curve.
