In the past, it was difficult to fix an adherend sufficiently during polishing processing and to peel off the adherend conveniently. The aneurysm embolic device includes an expandable sealing member having a circular joining member and reinforcing spokes which give the sealing member a slightly cupped configuration. A spherical ball is provided to project a part thereof from an opening. Mapping may be static and determined at processor design, programmable, with data stored and amendable, or conditional and dynamic, the interrupt logic executing an algorithm sensitive to variables to determine the mapping. A user dictionary of macro definitions is used to determine whether the first keystroke is part of a macro input pair. The member has a surface region overlying a bulk region, and comprises a shape memory alloy and boron.
