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. The cylindrical shaft has a pair of intermediate, symmetrically disposed, offset, coplanar grip portions formed by trapezoidal bends in the shaft, defining a main longitudinal axis and an offset longitudinal axis. The machine vision system further includes a microcontroller or similar device for interpreting both portions of the image. The peeling mechanism 4 feeds a forwardmost one the polarizing films F to a laminating mechanism 5 while peeling off the releasable liner therefrom by a knife-edged member. The processor is adapted to determine position location information in response to receiving and identifying the first plurality of corresponding signals and the second plurality of corresponding signals. The solder paste material is then formed into precisely controlled ball shapes and geometries.
