  • Publication number: 20180080935
    Abstract: An object of the present invention is to provide a method for collecting highly accurate data for diagnosis, useful in diagnosing the presence or absence of extrahepatic bile duct carcinoma, intrahepatic bile duct carcinoma, or gallbladder carcinoma, and a kit for diagnosis. When the concentration of CEACAM1 in a blood sample collected from a test subject is detected using a kit for diagnosis comprising an antibody specifically binding to CEACAM1 or a labeled product thereof, or the like and the CEACAM1 concentration is higher than the concentration of CEACAM1 in a blood sample derived from a non-carcinoma control subject or higher than a certain threshold value (cutoff value), data can be collected for diagnosing the test subject as having a high possibility of having extrahepatic bile duct carcinoma, intrahepatic bile duct carcinoma, or gallbladder carcinoma.

  • Publication number: 20170056187
    Abstract: The present disclosure relates to prosthesis systems having trays and liners having an asymmetrical locking mechanism to bias the strength of the liner to resist loading forces and associated methods. The tray has a lateral groove disposed in an inner surface of a lateral circumferential portion of the tray and a medial groove disposed in an inner surface of a medial circumferential portion of the tray. The liner has an upper segment and a lower segment. The liner has a locking portion for lockingly engaging the tray that includes the lower segment. The locking portion has a lateral toe positioned generally diametrically opposite a plurality of resiliently deformable medial fingers defined therein. The liner and the tray are engageable in a lateral-to-medial direction so that the plurality of medial fingers can resiliently deform to engage the medial groove subsequent to engagement of the lateral toe within the lateral groove.

  • Patent number: 8545504
    Abstract: The present invention relates to a set of tools and accessories used for properly positioning a stemmed humeral component, and/or a humeral stem provisional, within a canal in the humerus. The set of tools and accessories includes one or more fin clamps that are configured to be temporarily attached to a fin on the humeral component or the provisional; a ruler that is configured to be attached to the arm of the fin clamp, a fixation pin and pin driver configured to be used with the other tools for marking a position on the humerus; and one or more sleeves that are configured to slide over the stem of the humeral stem provisional to maintain it in the desired position.

  • Patent number: 8260810
    Abstract: Case images are registered so as not to cause bias (or partiality or imbalance) in amounts of feature of the case images included in a database of a similar image search system for image diagnosis. Since registration of the case images to the database is controlled according to degrees of similarity of the amounts of feature, it is possible to prevent a lot of similar case images from being included in the search result. Thus, it is possible to reduce possibility of representing a similar search result which may interfere with an accurate diagnosis by a diagnostician.

  • Patent number: 7942882
    Abstract: An ancillary tool for fitting a humeral component of a total or partial elbow prosthesis, comprising a guiding tool (30) for boring a humeral trochlea (T) along a geometric axis (X-X?) of bend of a joint to be equipped with said prosthesis. The guiding tool (30) includes a stirrup element (31) and means (32b, 33b) for securing said stirrup element on the humeral trochlea (T) so that said guiding tool defines a guiding zone that is aligned in the geometric axis of bend for the introduction (F1) of a drill (40), a punch or the like, in the humeral trochlea (T) along said geometric axis of bend. This ancillary tool also comprises at least one stepped template (701, 702, 703) for determining an anterior offset of said geometric axis of bend (X-X?) with respect to a humeral diaphyseal axis (Y-Y?).

  • Patent number: RE42805
    Abstract: A humeral component, forming a first articulating surface, and an ulnar component forming a second articulating surface adapted to be disposed around a part of the first articulating surface and to pivot about its longitudinal axis. This ulnar component is provided with structure for mounting a locking element which forms a third articulating surface extending the second and adapted likewise to be disposed around a part of the first surface. These mounting structure comprise guiding structures adapted to cooperate with complementary structure provided on the locking element in order to guide this element in translation with respect to the ulnar component, up to a position where blocking structure provided respectively on the locking element and on the ulnar component may be employed to immobilize this element on this component, these blocking structure being able to be employed only in this position.
