<P>PROBLEM TO BE SOLVED: To provide an expandable vessel implant or the like which is inserted into an aneurysm or the like and forms an embolization there. <P>SOLUTION: A compressible vessel implant which is formed of a foam material has a compressed configuration and can be expanded into a configuration which substantially matches the shape and size of the vessel site where an embolization should be formed. The implant is preferably formed of a hydrophilic and microporous foam material. It has an initial configuration of a scale-reduced model of the vessel site and can be compressed into a compressed configuration. The implant is made by creating a digital scanned data set by scanning the vessel site, a three-dimensional digitized virtual model of the vessel site by using the scanned data set, forming a scale-reduced physical mold of the vessel site by using the virtual model and forming the vessel implant in the shape of the scale-reduced model of the vessel site by using the mold. <P>COPYRIGHT: (C)2009,JPO&INPIT |
