IceSense3™ 

 

 

You can move from the automatic mode AT ANY TIME by pressing the Manual mode button 
on the screen, without interrupting the procedure. When in Manual, you can’t go back to 
Automatic mode.

 

o

 

If you do so, proceed as explained in section Manual freeze mode: press the Action 
button on the cryohandle to move from freeze to thaw and monitor the process 
under ultrasound.  

 

 

Figure 59: Freeze screen in Automatic mode  

During the preprogrammed procedure the system provides information regarding treatment 
progress: 

 

The left side of the screen displays the Current Step (freeze, thaw, or warm cycle) and time 
left for this cycle. 

 

The right side of the screen displays information concerning the overall Protocol, including 
total protocol time, time elapsed, protocol format, and changes you have made, if any, to the 
preprogrammed protocol. 

 

 

 

5.3.6

 

Thaw 

During Thaw, the iceball melts partially or totally depending on the thaw time and the tissue 
properties. 

It is clinically important to have a thaw cycle between two freeze cycles and to keep the probe 
location steady in the target tissue during all of the thaw period. Control the process under 
Ultrasound or any other imaging system.
