  • Publication number: 20090054835
    Abstract: A catheter control assembly 10 includes a support structure 12. A drive arrangement 14 is supported by the support structure 12. An elongate displacement mechanism 16 is associated with the drive arrangement 14 to be displaced at least axially under the action of the drive arrangement 14. A carrier 20, for mounting at least a part of a catheter handle 22, is mounted on the displacement mechanism 16, the carrier 20 comprising a plurality of independently displaceable receiving formations 102, 104 and 106, each receiving formation 102, 104 and 106, in use, receiving a part of the catheter handle and at least two of the receiving formations 102, 104 and 106 being axially displaceable relative to each other.

  • Patent number: 5217595
    Abstract: An electrochemical sensor for sensing a gas dissolved in a liquid. The sensor includes a probe having a cylindrical body and a rounded face. A working electrode, a reference electrode and an auxiliary electrode are buried in the probe body and have distal ends reaching conformingly to the face. A pulsed polarizing voltage is impressed between the auxiliary electrode and the working electrode for polarizing the probe, and a capacitor is provided for storing the charge which flows to the working electrode during periods of polarization. The concentration of the dissolved gas is determined by measuring the voltage across the capacitor.
