  • Patent number: 10617421
    Abstract: The present invention relates to a connection stent and a method of manufacturing the stent. The connection stent includes: a body configured to form a plurality of cells through the intersection of wires, and provided in a hollow cylindrical shape; an upper head formed to extend from one end of the body to have a diameter larger than that of the body; and a lower head formed to extend from a remaining end of the body to have a diameter larger than that of the body. The upper head and the lower head are respectively placed to come into contact with insides of heterogeneous tissues. Accordingly, according to the present invention, there can be manufactured a stent which can connect heterogeneous tissues and form a bypass and which can provide sufficient expansion force and minimum axial force for the maintenance of the bypass formed as described above.

  • Publication number: 20170252192
    Abstract: The present invention relates to a catheter for a stent operation. The catheter for a stent operation according to the present invention comprises: a solid bar of which one end is coupled to the side of a handle; an outer tube into which the solid bar is inserted, having an insertion hole through which a guide wire can be inserted from the outside to the inside, and of which one end is coupled to the side of the body; a guide tip coupled to the side of the solid bar, and guiding the guide wire by having a through-hole through which the guide wire passes; a connection tube for connecting and coupling the guide tip to the solid bar, wherein the solid bar has an accommodation groove, for preparing a space capable of accommodating the guide wire, formed in a predetermined section of a region to be connected to the connection tube, such that the guide wire can be accommodated inside of the outer tube.

  • Publication number: 20170181872
    Abstract: The present invention provides a hybrid stent for a blood vessel, the stent including: a plurality of first wires configured to form a plurality of rows in one direction and maintain the shape thereof inside a human body; a plurality of second wires configured to intersect the first wires and form a plurality of rows; and connectors configured to connect portions where the first wires and the second wires intersect each other; wherein a plurality of hollow holes are formed by the first wires and the second wires, and one or more of the plurality of second wires are degraded inside the human body after a predetermined period of time. Accordingly, the effect of enabling the stent to be easily removed can be expected because the second wires made of the biodegradable polymer are gradually degraded by body fluids.
