1.0 INTRODUCTION
This manual should be reviewed with all personnel involved with CR4000 systems to insure proper and
safe use.
The MIRA CR4000 and the interchangeable probes were designed to meet the exacting and practical
needs of Ophthalmologists who perform Cryosurgery. The system rapidly freezes or defrosts probe tips
while the ergonomically designed handles remain warm. It is non-electric, can be used with medical
grade CO
2
or N

O (non-siphon cylinders) and has three pre-selected temperature settings. The unique
design of the MIRA Cryo probe isolates the gas expansion chamber at the very tip of the probe, thereby
assuring that freezing and defrosting the probe, thereby assuring that freezing and defrosting occurs only
at the target area. Tip-only freeze also eliminates the need for an insulating boot, which can obscure the
surgeon’s view
The MIRA CR4000 has a rapid freeze and defrost cycle available, providing greater control of
application time.
Temperature settings for both CO
2
and N

O allow for pre-selected tip temperatures.
The choices of temperatures are -65, -35 and -5 (+/-5deg.C) for CO

and -85, -55 and -25 (+/- 5 C) for
