<P>PROBLEM TO BE SOLVED: To provide a dilator which is thin-walled, then has a larger inner diameter as much as possible, has a high rigity, and has a satisfactory sliding property, that is, a low surface frictional resistance. <P>SOLUTION: The dilator is obtained by extending a fluorocarbon resin tubular body (tube), which is molded by melt-molding, at temperature not lower than a glass transition point and not higher than a melting point, and then, annealing it. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
