Abstract
A medical device in which a part to be secondarily shaped comprises a molded silicone rubber article is subjected to heatless shaping by irradiation with electron-rays. The irradiation with electron-rays enables shaping and, furthermore, sterilization under some conditions. In a medical device comprising a part in which at least a silicone rubber is used and the mechanical properties of the silicone rubber preferentially appear, the shape of the above-described part upon molding is deformed with the use of a correcting member to a level exceeding the desired deformed shape and maintained in this state. Next, electron-ray irradiation is conducted in this state and then the correcting member is eliminated. Thus, the desired deformed shape intermediate between the shape upon the molding and the shape upon the electron-ray irradiation can be obtained.
