  • Patent number: 10695163
    Abstract: This invention provides a stent-graft that has both shape-maintainability and flexibility, and when implanted in a living body, the stent-graft performs its intended functions for a considerably long period of time relative to conventional stent-grafts, without causing conflict. The stent-graft comprises a stent comprising multiple elastic rings and a graft. An auxiliary elastic wire whose rigidity is lower than that of the stent is arranged at the end-part of the graft, and the auxiliary elastic wire is connected to the multiple elastic rings at the opening part.

  • Patent number: 7422472
    Abstract: To provide a connector that includes a locking section having a high strength, and is excellent in shielding performance. Contacts are held by a housing including a receiving space into which is inserted FPC. An actuator is mounted in the housing in a manner pivotally movable between open position for inserting FPC into the space, and closed position for holding FPC therein. The housing is covered with a shield plate. The shield plate includes a contact portion for contact with a ground line of FPC, a terminal portion for contact with a printed circuit board, and a seesaw-type locking section for preventing FPC from being removed. A nail portion is formed at one end of the locking section, for engagement with FPC, and a power point portion on which a pivotal force of the actuator acts is formed at the other end. The actuator is provided with a third cam portion which is operable when the actuator is in closed position, to move the power point portion such that the nail portion comes closer to FPC.

  • Patent number: 7416438
    Abstract: A connector capable of facilitating the insertion of a connected object, and obtaining a sufficient contact force. Contacts are held by a housing including a receiving space into which is inserted FPC. An actuator is mounted in the housing in a manner pivotally movable between open position for inserting FPC into the space, and closed position for holding FPC therein. The contacts have respective seesaw-type beams having one ends thereof formed with portions for contact with FPC, and the other ends thereof formed with power point portions for receiving the turning force of the actuator. The actuator has pressing portions for pushing downward the power point portions when open, to thereby lift them to move the contact portions out of the space, and cam portions for pushing upward the same when closed, to thereby push them downward to cause the contact portions to enter the space.
