A method for fixing one of a balloon and a tubular member to an object
with a thread for a medical equipment, may include covering the object
with an end of the one of the balloon and the tubular member, winding the
thread at a first pitch in a first direction from an edge of the end of
the one of the balloon and the tubular member toward an intermediate
position of the one of the balloon and the tubular member, and winding
the thread at a second pitch in a second direction opposite to the first
direction, the second pitch being shorter than the first pitch.
