Abstract: A catheter for diagnosing and performing an interventional procedure on tissue has an elongated catheter shaft, and optical fibers, extending through the catheter shaft, for transmitting light to tissue located at a distal end of the catheter and conveying light back from the tissue for analysis by a spectroscopic diagnosis system to determine whether an interventional procedure should be performed on the tissue. An interventional device is located at the distal end of the catheter for engaging tissue diagnosed by the spectroscopic diagnosis system in order to perform the interventional procedure on the tissue.

Abstract: A patient supporting table top for X-ray inspection apparatus which includes a platelike core member formed by mixing thermosetting resin with a great number of hollow carbon microspheres reinforced with carbon fibers and press-heating these materials. A covering member is bonded to each side of the core member by using an adhesive agent such as epoxy resin. The covering member is formed by mixing resin material with carbon fiber network and press-heating these materials.
