Patent number: 11020253Abstract: The present invention relates to a multi-hole stent for digestive organs, the multi-hole stent including: a body configured to form a plurality of cells through the intersection of wires and to be provided in a hollow cylindrical shape; and a film configured to be installed in contact with the inner surface of the body; wherein one or more discharge holes are formed in the film. The multi-hole stent for digestive organs is placed in a stenotic region in a biliary track, and can thus secure a discharge path by restoring a narrowed diameter. Furthermore, the film is installed on the inner surface of the body, and can thus prevent the entry of a lesion into the stent and re-stenosis attributable to the growth of the lesion and can thus provide discharge paths for body fluids generated from side branches through the discharge holes formed in the film.Type: GrantFiled: June 23, 2016Date of Patent: June 1, 2021Assignee: M.I. TECH CO., LTD.Inventors: Hun Kuk Park, Bong Seok Jang, Ho Yun, Jong Pil Moon, So Mi Ji, Kyoung Sub Shin, Makoto Kobayashi

Patent number: 10932928Abstract: The present invention relates to a drug-releasing biodegradable stent. The drug-releasing biodegradable stent includes: a first stent structure configured to have a plurality of cells by means of the wire crossing pattern of a woven structure and be provided in a hollow cylindrical shape by weaving a metal wire made of a shape-memory alloy in a specific pattern on a jig; and a second stent structure formed as a 3D print that is provided to have a plurality of cells by means of the wire crossing pattern of a printed structure and also have a hollow cylindrical shape by performing 3D printing using a printing material including a biodegradable polymer and a drug, and disposed such that it covers the outer circumferential surface of the first stent structure or the outer circumferential surface thereof is covered with the first stent structure.Type: GrantFiled: November 1, 2016Date of Patent: March 2, 2021Assignee: M.I.TECH CO., LTD.Inventors: Hun Kuk Park, Jong Pil Moon, Bong Seok Jang, Ho Yun

Patent number: 10617421Abstract: 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.Type: GrantFiled: May 24, 2018Date of Patent: April 14, 2020Assignee: M.I. TECH CO., LTD.Inventors: Jong Hyeon Han, Hun Kuk Park, Ho Yun, Jong Pil Moon, Bong Seok Jang

Patent number: 10449068Abstract: The present invention relates to a method for manufacturing a stent, the method using a jig in which detachable protruding pins are installed at all respective location points at which circumference division lines and length division lines intersect each other, the method forming cells through intersection of wire by setting any one of the location points as a start point and repeatedly bending and moving the wire from the start point upward and downward to pass over the protruding pins located in diagonal directions, wherein a first stent woven such that intersection portions formed through the intersection of a wire are spaced apart from each other in a diagonal direction and arranged one for each length division line and a second stent woven to maintain the structural stability of the first stent and to prevent the first stent from being twisted can be provided as a single stent.Type: GrantFiled: May 12, 2015Date of Patent: October 22, 2019Assignee: M.I.TECH CO., LTD.Inventors: Hun Kuk Park, Jong Pil Moon, Bong Seok Jang, Ho Yun
