Patent number: 11013623Abstract: The present invention relates to a stent and a method for manufacturing the same. The stent includes: a first hollow cylindrical body portion formed by weaving a metal wire; a second hollow cylindrical body portion formed by weaving a metal wire, and configured to surround the first body portion; an expanded portion configured to form two adjacent ends of the first body portion and the second body portion integrally; and a membrane inserted between the first body portion and the second body portion, and configured to surround the outside of the first body portion. According to the present invention, there is no risk of the film being torn when the stent is bent, an additional connection wire is not required, the process of manufacturing the stent is simple, and the costs required for the manufacture of the stent are not high.Type: GrantFiled: January 9, 2019Date of Patent: May 25, 2021Assignee: M.I.

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
