Abstract: A FPD navigation device includes an image acquiring portion that acquires, from a FPD (flat panel detector), a first image including an image of a target blood vessel taken at a first position, and a second image including an image of the target blood vessel taken at a second position different from the first position; a position information acquiring portion that acquires position information on the target blood vessel from the first image, the second image, position information on the first position, and position information on the second position; and a recommendation range output portion that outputs, from the position information on the target blood vessel, a FPD imaging position recommendation range representing a range of an imaging position of the FPD recommended for acquiring an image of the target blood vessel.

Abstract: A guide wire including a core shaft including a distal end portion having a pseudoelastic property, a tip joined to a distal end of the distal end portion of the core shaft, and an auxiliary wire that is arranged parallel to the distal end portion of the core shaft. The auxiliary wire has a distal end joined to the tip and a rear end joined to the core shaft. The auxiliary wire has a high flexibility, a high breaking strength, and a short breaking elongation compared to the distal end portion of the core shaft.

Abstract: A guide wire includes a core shaft formed of superelastic metal, where the core shaft has a tapered portion having a diameter decreasing from its proximal end toward its distal end, an intermediate portion that is cylindrical and is adjacent to the proximal end of the tapered portion, and a proximal portion adjacent to a proximal end of the intermediate portion and having a maximum diameter larger than a diameter of the intermediate portion; a coil body covering at least a part of the intermediate portion and the tapered portion of the core shaft, the coil body having an outer diameter of 0.36 mm or less; and a distal tip disposed at a distal end of the coil body and forming a distal end of the guide wire, the diameter of the intermediate portion being 0.22 to 0.24 mm.

Abstract: A command conversion device 14 is connected between an amplifier device 11 and a portable player 13. The amplifier device 11 sends/receives a plurality of types of first commands corresponding to a plurality of types of devices (e.g., CD players, MD recorders, tape recorders, etc.), and performs an operation based on a received first command. The portable player 13 sends/receives a second command, and performs an operation based on a received second command. The command conversion device 14 includes a selector for selecting a type of a first command, and a converter. When a first command of the type selected by the selector is received from the amplifier device 11, the converter converts the received first command into a second command, and sends the second command to the portable player 13.
