In a guide wire (l), a core line (2) has a proximal side wire (4) and a distal side wire (5), the latter of which is to be connected to a front end of the proximal side wire (4). The distal, wire (5) is smaller in rigidity and superior in restitution than the proximal side wire (4). A concave portion (51) is provide...

A medical guide wire (1) has a helical spring body (3), a distal end portion of which has a radiopaque helical portion (31), and an elongate core (2) placed within the helical spring body (3). The elongate core (2) has a distal end portion (21) diametrically thinned and having a proximal end portion (22) diametrical...

[Problem] In GSR sensor elements times ti and tm for detecting rising pulses are set close to each other the induction voltage at the time tm is substantially high and thus the fluctuation caused by the magnetic field cannot be ignored. The present invention realizes a rising pulse detection-type GSR sensor by elimi...

[Problem] There is a demand for further reductions in the size and thickness of three-dimensional magnetic field detection elements as well as for improvements in the magnetic field detection capability thereof in order to expand usefulness into e.g. a wearable computer having a direction sensor or the distal end of...

In order to improve the linearity of rising pulse detection to 0.5% or less to enhance magnetic sensitivity and linearity, which are advantages of rising pulse detection, this magnetic sensor has a configuration in which two magnetic wires (21, 22) are installed in one coil (3) and pulse currents are caused to flow ...
