A unidirectional handle device for an endoluminal device includes an outer tubular member and an elongate inner member slidably received in the outer tubular member. A semiconductor device 100 is equipped with a substrate 2, having a bottom surface 2b and an element mounting surface 2a which is positioned on the opposite side of bottom surface 2b, and a semiconductor element 1, having a main surface 1a which is mounted onto element mounting surface 2a. The input signal may be generated in a pulse generator to have an input pulse duration less than or equal to that of the oscillating signal.
