ABSTRACT:
A process for producing a medical device having a branch includes the steps of: welding a bottom of the tubular member on a mounting surface of a constituent material of a main tube extruded under elevated temperature, welding firmly the bottom of the tubular member to the mounting surface of the main tube while aspirating the constituent material of the main tube from above the tubular member, forming a hole in the mounting surface of the main tube so as to communicate an interior of the tubular member with an interior of the main tube, and cutting the main tube, thereby assembling the medical device having the branch.
