Essential Performance, Catheter Operating
Temperatures
The catheters are designed to image under physiologic conditions. Operating Temperature
of all solid-state array catheters used with the Volcano system is <55 +/- 0.3 °C in air and
<41+/- 0.3 °C under physiologic conditions (37 °C in fluids). Operating Temperature of
rotational catheters used with the Volcano system is 1 +/- 0.3 °C above ambient
temperature in air and <38 +/- 0.3 °C under physiologic conditions (37 °C in fluids).
Operation of the catheters in air will degrade the life of the catheter, and is not
recommended. Should operation of the solid-state array catheters in air occur, this will
result in a temperature at the distal end of up to 55 °C, but the catheters thermal load is
negligible and the catheters may be safely touched. They will feel slightly warm to the
touch under these conditions. Should operation of the rotational catheters in air occur, this
will result in a negligible temperature rise at the distal end.
Essential Performance, System
The essential performance of the Volcano system when operating with Volcano catheters
is specified below:
The rotation of the Revolution catheter imaging transducer at the distal tip of the
catheter is automatically maintained at a predetermined speed during live
imaging operations
If present, any signal distortion leading to errors of diagnostically relevant
parameters is visually evident to the operator
The ultrasound (acoustic) output and heating of the catheter imaging transducer
is maintained within safe levels
