Abstract: An optical fiber is positioned in a lumen of a sheath so a gap exists between the sheath and optical fiber. A filling member fills part of the longitudinal extent of the gap and fixes the optical fiber. The gap is devoid of the filling member over a part of the longitudinal extent of the of the optical fiber so that an air gap exists between the optical fiber and the sheath. In the event bending, expansion and/or contraction are applied to the sheath, the stress is inhibited from being transmitted to the optical fiber. If the sheath is expanded and contracted, one end of the optical fiber is open and so the optical fiber is not expanded/contracted like the sheath expansion and contraction. Consequently, stress is not likely to be transmitted to the optical fiber and so it is possible to maintain a constant length of the optical fiber.

Abstract: A coupling device for coupling optical fiber cables reduces contact with the internal parts when coupling a connector. The coupling device includes a projection of a connector device housing insertable into a groove of an adapter device groove of an adapter device housing. The coupling device which connects optical fiber cables compresses an elastic member, and connects an optical fiber connector of the connector device and the optical fiber end on the adapter device side.

Abstract: An imaging apparatus for diagnosis is connected detachably with a probe having a first transmitting and receiving unit repeating electric signal transmission and reception and a second transmitting and receiving unit repeating optical signal transmission and reception, obtains a reflected signal inside a body cavity or lumen from the first or second transmitting and receiving unit by rotationally operating the first and the second transmitting and receiving units inside the body cavity, and can generate a tomographic image inside the body cavity, wherein the apparatus includes an electric rotary connector carrying out transmission of the electric signal while rotationally operating the first and second transmitting and receiving units; and an optical rotary connector carrying out transmission of the optical signal, the electric rotary connector includes a metal surface on the rotational drive unit side and a brush on the fixed unit side that is operable between contact and non-contact positions.

Abstract: A coupling device for coupling optical fiber cables facilitates positioning in a circumferential direction for coupling a connector. When a connector fixing member is inserted into an adaptor fixing member, a protruding section of the connector fixing member slides along an end surface of the adaptor fixing member, and is automatically guided to a notched section.

Abstract: A vascular incision apparatus is composed in part of a needle for puncturing a blood vessel and a cutter for making an incision in the blood vessel. The apparatus easily, rapidly and reliably creates a vascular incision of the desired length by employing an incision length controlling means to control the length of penetration by the needle into the blood vessel, or by controlling the distance between the respective needle points on first and second needles which face each other across a given distance, one of which needles is movable relative to the other.

Abstract: A temperature measuring unit of a temperature sensor has electrodes disposed on the upper and lower surfaces of a temperature measuring element, thin-film substrates disposed on the upper and lower surfaces of the electrodes, and laser beam shield plates disposed on the upper and lower surfaces of the thin-film substrates. One of the electrodes is bonded to the temperature measuring element by a conductive adhesive, and the other electrode is not bonded to the temperature measuring element by a conductive adhesive. When the temperature sensor is bonded to a hollow cylinder of an insert, the temperature measuring unit is curved along the surface of the hollow cylinder, tending to develop tensile stresses in the other electrode. At this time, the other electrode is positionally displaced depending on the developed tensile stresses, allowing the temperature sensor to be adjusted in length. Consequently, the temperature sensor is prevented from being broken or damaged.

Abstract: A vascular incision apparatus is composed in part of a needle for puncturing a blood vessel and a cutter for making an incision in the blood vessel. The apparatus easily, rapidly and reliably creates a vascular incision of the desired length by employing an incision length controlling means to control the length of penetration by the needle into the blood vessel, or by controlling the distance between the respective needle points on first and second needles which face each other across a given distance, one of which needles is movable relative to the other.
