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: 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.
