  • Publication number: 20220205931
    Abstract: A measurement device that measures an amount of moisture in a medium. The device includes a transmitter that transmits an electrical signal including an incident wave to one of a pair of probes in which a cable has been embedded through the cable. A receiver receives a reflected wave obtained from reflection of the incident wave by the one of the pairs of probes and a transmitted wave that has been transmitted through a medium between the pair of probes through the cable. A processing unit obtains a reciprocating delay time corresponding to a time over which the electrical signal reciprocates through the cable and measures an amount of moisture contained in the medium on the basis of the reciprocating delay time and a propagation transmission time corresponding to a time over which electromagnetic waves propagate and the electrical signal is transmitted through the medium and the cable.

  • Publication number: 20220152357
    Abstract: A steerable catheter includes a flexible tube having a distal end and a proximal end. The tube includes a first tube section (sheath body section) the flexibility of which does not substantially change even upon receiving compression force in the axial direction; and a second tube section (deflection section) joined so as to be continuous with the distal end of the first tube section and constituted by a porous tube becoming hard upon being compressed according to the degree of the compression force acting in the axial direction and returning to being soft when the compression force is released. The tube includes operation means (wires) for releasably exerting a compression force compressing the second tube section in the axial direction and a deflection force deflecting the second tube section. According to some embodiments, both operability and insertability of the steerable catheter can be improved.
