Abstract: A stent and a securely-installed artificial valve replacement device having the same, the stent being of a cylindrical structure; the top of the stent is provided with a fixed ear (60); the fixed ear (60) has a neck portion (601) connected to the top of the stent, and a head portion (602) engaged with the fixed head of the stent; the head portion (602) has a bending structure for improving the overall radial thickness; and the artificial valve replacement device is comprised of a stent and a prosthetic valve fixed on the stent. The stent with a bending structure overcomes the problem of easily disengaging from the fixed head of the stent, while not affecting the release of the stent.

Abstract: A multi-stream service concurrent transmission method includes: a multi-interface terminal initiating a service transmission request to a network side; the multi-interface terminal receiving information of database servers capable of providing the requested service resources and service information of the requested service; the multi-interface terminal establishing a plurality of concurrent links with the database servers, dividing service data packets of the requested service, and notifying the network side of the division result; the multi-interface terminal receiving the service data packets of the requested service via the plurality of established concurrent links. The embodiment of the present document further correspondingly discloses a multi-stream service concurrent transmission subsystem, system and a multi-interface terminal.

Abstract: A device and service discovery method and a piece of device middleware are provided.

Abstract: The present invention discloses a method of data retransmission in coordination service transmission and access network gateway thereof. Wherein, the method includes: in coordination service transmission, access network gateway receives the service data requested by the coordination terminal, caches the data and transmits it to the corresponding destination terminal; the access network gateway executes retransmission strategy, and when decides data retransmission is needed, retransmits the cached data to the corresponding destination terminal. The access network gateway is used to receive the service data requested by the coordination terminal, to cache the data and transmit it to the corresponding destination terminal, to retransmit the cached data to the corresponding destination terminal when data retransmission is needed. Using the present invention, to the problem of service data retransmission in coordination service transmission, the service data transmission efficiency is effectively improved.

Abstract: The present invention provides an anti-fracture sheath. The anti-fracture sheath comprises a tube body and an expansion section for accommodating an implantable device, wherein one side of the distal end of the tube body is joined with the expansion section, at least two reinforcing ribs are axially arranged on the tube wall of the expansion section in an internally extending manner, and the proximal ends of the reinforcing ribs extend from the expansion section and are fixedly connected with the tube wall of the tube body; and the materials of the reinforcing ribs are Kevlar fibers, the diameter of each reinforcing rib is from 0.03 mm to 0.12 mm, and the number of the reinforcing ribs is from two to four. The anti-fracture sheath provided by the present invention has the advantage that the strength of the expansion section is improved when the whole compliance of the sheath is maintained, thereby avoiding fracture of the sheath in an implantable device releasing process.

Abstract: Disclosed in the embodiments of the present invention are a method, device and system for mobility management as well as a computer storage medium. The method comprises: reception by an MME of a service command and extraction from same of service information; determining on the basis of said information which wireless networks are accessed by each terminal of a terminal cluster; invoking, on the basis of the wireless network accessed by each terminal of a terminal cluster, the service requested by each such terminal of a terminal cluster.

Abstract: Disclosed is a thrombus filter comprising a sheath (1), a thrombus intercepting net (2) with an intercepting port, a first pushing piece (4) and a control handle. The thrombus filter is also provided with prevention umbrella (3), wherein the direction of the opening of the overfill prevention umbrella (3) is identical to that of the intercepting port. The overfill prevention umbrella (3) is provided outside the thrombus intercepting net (2). A second pushing piece (5) is located in the sheath (1) to push and pull the overfill prevention umbrella (3). The overfill prevention umbrella (3) comprises an umbrella surface (32) and an umbrella stand (31) connected between the second pushing piece (5) and the umbrella surface (32), and the open end of the umbrella surface (32) is a closed shape memory.
