  • Publication number: 20130178886
    Abstract: An occlusion device comprises a distal end, a proximal end and an elastic braided body which is provided between the proximal end and the distal end and made of wires. The elastic braided body is composed of a multi-stage braided net, which comprises at least a first-stage braided net that is closest to the distal end and made of a plurality of first-stage wires, and a second-stage braided net which is braided by a plurality of first-stage wires and second-stage wires all together. The minimum cross-section area of the first-stage braided net after being compressed toward the direction perpendicular to an axis of the elastic braided body is less than the minimum cross-section area of any other-stage braided net after being compressed toward the axis. A method for manufacturing the occlusion device is also provided.

  • Publication number: 20130150879
    Abstract: An interventional medical device connector and a method for using same. The interventional medical device connector comprises an implant (1) and a pusher (5). One end of the implant (1) is provided with at least one lock ring (9). The top end of the pusher (5) is provided with at least one locking hole (7). The pusher (5) is provided with at least one control wire (4). The control wire (4) slides along the axial direction of the pusher (5), and the top end of the control wire (4) can reach at least one of the locking holes (7). The control wire (4), the lock ring (9) and the locking hole (7) together form a connection means having a lock-pin structure. Use of this means of connection effectively overcomes the defects of existing threaded connections, reduces risks, and provides convenience of use.

  • Publication number: 20100259138
    Abstract: A glove box with a leakage shielding space (4) comprises a main box body, a view window (8) placed on the main box body, glove ports installed on the view window (8), side panels attached to the main box body, and an antechamber (1) installed on a side panel. Wherein, on at least one of five interfaces, namely, between the main box body and the view window (8), between the main box body and the side panel, between the view window (8) and the glove port, between the glove port and the glove, between the side panel and the antechamber (1), a leakage shielding space (4) is formed, so as to ensure the purity in the operating space of the glove box and to prevent the external environment of the box body from being polluted.
