Publication number: 20140114343Abstract: Disclosed is a stent for the coil embolization of a cerebral aneurysm. The stent according to one embodiment of the present invention is shaped as a cylinder formed of a mesh-structured metal thin wire to enable a coil to fill the inside of said cerebral aneurysm through the mesh of the stent. And the stent has such a shape as the maximum diameter of the center portion of the stent is larger than the maximum diameter of each of both end portions of the stent. For example, the stent may have a fusiform shape in which the center portion protrudes further than the end portions.Type: ApplicationFiled: May 23, 2012Publication date: April 24, 2014Applicant: THE ASAN FOUNDATIONInventors: Deok-Hee Lee, Seon-Moon Hwang, Tae-Il Kim, Ok-Kyun Lim, Sung-Min Kim, In-Chul Yang
