To provide a fluorine-containing adhesive which maintains thermal resistance, chemical resistance, weather resistance and electric insulating property and has strong adhesive property directly to substrates particularly metal and glass, and an adhesive film and laminated article which are obtained by using the fluorine-containing adhesive. In one embodiment, the group delay precompensator circuit includes: a Cartesian feedback loop coupled between an output of the power amplifier and an input of the RF transmitter; and a group delay compensation block, located in the Cartesian feedback loop, that introduces an opposing phase characteristic into the Cartesian feedback loop and thereby precompensates for the phase distortion. The arm supports cooperate with the back support in order to provide support for a patient’s arms and upper body. A bidirectional optical add-drop multiplexer optically communicates with the waveguide. The setting processing unit sets a region of interest based on the position of end point of the catheter. A wiper is optionally provided to remove bodily fluids from the tether when pulled from the body lumen past the sensor.
