Abstract: A file conversion method for LSI design data, which converts LSI design data files described by a first format into source data of a list type structure expressed by lists of cells and nodes, and stores the source data in a memory, and converts the source data of the list type structure stored in the memory into LSI design data files described by a second format.

Abstract: An endoprobe includes a tubular element having a proximal end and a distal end. At least one optical fiber element is disposed within the tubular element. A plurality of laser light outlets are defined through a side wall of the tubular element. The at least one optical fiber element is adapted to conduct laser light from the proximal end of the tubular element to the plurality of laser light outlets, thereby to direct laser light radially of the tubular element. The tubular element is arcuately curved along a portion of its length, adjacent its distal end and the laser light outlets are defined along a radially inner portion of the curved portion.
