OVERVIEW
Introduction
ProSense™ Cryoablation System is a comprehensive system for cryotherapy of human
tissue based on IceCure™ Medical’s technology. All established cryotherapy techniques
utilize a low temperature cryogen under pressure. The ProSense™ Cryoablation System
utilizes liquid nitrogen that causes the cryoprobe to reach very low temperatures thereby
freezing tissue with which it comes in contact.
Intended use
ProSense™ cryoablation system is intended for cryogenic destruction of tissue during
surgical procedures by the application of extreme cold temperatures. The ProSense™
cryoablation system is indicated for use as a cryosurgical tool in the fields of general
surgery (including breast and liver tissue), dermatology, thoracic surgery (including lung
tissue), gynecology, oncology (including Musculoskeletal tissue), proctology, and urology
(including kidney tissue). The ProSense™ cryoablation system may be used with an
ultrasound device to provide real-time visualization of the cryosurgical procedure.
This cryotherapy should only be executed if the operative standard therapy and established
therapies cannot be applied.

The liquid nitrogen Dewar supplied with the ProSense™ cryoablation system
is a dedicated system part and should not be used for any other purpose.
Make sure to use only IceCure™ approved and labeled Dewars for your
system.
Caution
Dewars should always be stored with their dedicated lids in place.
Caution
Only Dewars and lids supplied by IceCure™ Medical may be used with the
ProSense™ cryoablation system. Make sure to use only an approved
IceCure™ Dewar for your system.
Caution
Turn off the cryoablation system and lock the rollers when the system is not
in use.
Before you start a procedure, lock at least two of the four rollers.
Caution
The ProSense™ cryoablation system should be moved with care in order to
avoid damage to the system or other clinical equipment. When moving the
system, use the dedicated handle.
Warning
After Extraction step, before removing the cryoprobe from the tissue, make
sure that the freeze effect has been deactivated so that the cryoprobe can
easily be removed from the tissue.
Do not force removal of the cryoprobe from the tissue as it might increase
the risk of tissue damage. Continue the Extraction step or wait for passive
thaw until the cryoprobe can be withdrawn easily.

Warning
Verify cryoprobe S/N registration by double checking the serial number on
the package and on the cryoprobe itself. Entering an incorrect cryoprobe S/N
registration will result in cryoprobe nullification or incomplete treatment.
Warning
Do not allow any liquid or humidity to enter the cryohandle. Always keep
the cover on the cryohandle.
Warning
In case the Extraction process isn't available, Wait for passive Thaw.
Warning
In case of frost on shaft, if possible, start Extraction. If not, wait for passive
Thaw. In both cases use skin protection techniques.
Warning
Pay attention to the cryoprobe during functional test: bubbles, leak or frost
on shaft may signal internal problems that could be hazardous.
Warning
If you don’t press Skip after replacing Dewar, the system will stay in Thaw
mode.
Liquid nitrogen
Nitrogen gas is a potential asphyxiant. In the event of a large liquid nitrogen spill,
personnel should adhere to a predetermined evacuation plan. Seek medical help
immediately if breathing problems occur.
