1OVERVIEW
1.1 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.
1.2 Intended use
The IceCure Family device, including the ProSense cryoablation system is intended for
cryogenic destruction of tissue during surgical procedures by the application of extreme
cold temperatures. The IceCure Family device, including the ProSense cryoablation
system is indicated for use as a cryosurgical tool in the fields of general surgery ,
dermatology, neurology (including cryoanalgesia), thoracic surgery , ENT, gynecology,
oncology , proctology, and urology . The system is designed to destroy tissue by the
application of extreme cold temperatures including prostate and kidney tissue, liver
metastases, tumors, skin lesions, and warts. The IceCure Family device, including the
ProSense cryoablation system may be used with an ultrasound device to provide real-
time visualization of the cryosurgical procedure.
The system is suitable for use in a number of cryotherapy applications. However, it is
ONLY indicated for use in patients whom the practitioner has deemed eligible for
cryotherapy.
The IceCure Family cryoablation system is intended for cryogenic destruction of tissue
during surgical procedures by the application of extreme cold temperatures. The IceCure
Family device, including the ProSense cryoablation system is indicated for use as a
cryosurgical tool in the fields of general surgery, dermatology, neurology (including
cryoanalgesia), thoracic surgery , ENT, gynecology, oncology , proctology and urology as
detailed below. The system is designed to destroy tissue by the application of extreme
cold temperatures including prostate and kidney tissue, liver metastases, tumors, skin
lesions, and warts.

•palliation of tumors of the skin
•destruction of warts or lesions
Gynecology (ablation of malignant neoplasia or benign dysplasia of the female genitalia).
ENT (Palliation of tumors of the oral cavity and ablation of leukoplakia of the mouth).
General Surgery
•Ablation of leukoplakia of mouth, angiomas, sebaceous hyperplasia, basal cell
tumors of the eyelid or canthus area, ulcerated basal cell tumors,
dermatofibromas, small hemangiomas, mucocele cysts, multiple warts, plantar
warts, hemorrhoids, anal fissures, perianal condylomata, pilonidal cysts actinic and
seborrheic keratoses, cavernous hemangiomas, recurrent cancerous lesions.
•palliation of tumors of the rectum, hemorrhoids, anal fissures, pilonidal cysts, and
recurrent cancerous lesions, ablation of breast fibroadenomas)
•destruction of warts or lesions.
•palliation of tumors of the oral cavity, rectum, and skin.
•ablation of breast fibroadenomas.
Thoracic Surgery (ablation of arrhythmic cardiac tissue and cancerous lesions.
Proctology (ablation of benign or malignant growths of the anus and rectum and
hemorrhoids).
The system may be used with imaging device like ultrasound to provide real-time
visualization of the cryosurgical procedure

2.2.5 Clinical Assessment
2.2.6
Warning
Practitioners should be aware of the possibility of imaging findings at the site
of a cryoablated area. Practitioners should inquire if a patient has a history of
cryoablation.
Warning
Exercise caution when treating patients who have had previous difficulty
with surgical procedures or local anesthesia.
Warning
Safety and effectiveness of the ProSense™ cryoablation system in pregnant
women has not been established. Physicians should exercise caution when
using the cryoablation system in pregnant women.
Warning
The handle and hose portions of the ProSense™ cryoablation system may
become cold during the cryoablation procedure. Operators should consider
insulating these parts in order to prevent discomfort to the patient.
Warning
The supplier and manufacturer of the ProSense™ cryoablation system do not
claim that it will be useful for assisting with the treatment of any particular
condition or set of circumstances. Full responsibility for assessing the
potential benefit of the system for a given medical condition lies with the
practitioner.
While experience has shown that the system is useful for certain applications
in cryosurgery, no representation or warranty is made that the system is
useful for any specific person or condition.
Warning
For patients with breast implants, you must document that adequate
distance exists between the lesion and the implant to ensure that the ablated
lesion will not contact or jeopardize the implant, and there is enough space
to create the required margins.

Do not rely solely on the temperature sensor measurement. Always monitor
the procedure using Ultrasound or other appropriate imaging systems.
Caution
Artifacts from the devices may appear in the Ultrasound or CT image.
Warning
Temperature sensor and cryoprobe insertion and navigation within tissue
MUST be done under guidance of an appropriate imaging device.
Warning
You must NOT allow the freeze process to start before the cryoprobe active
area is actually within the target tissue.

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
If one or more of the wheels is damaged, do not use the system.
Warning
Cryoprobes are fragile and can be damaged if mishandled. Do not use a
cryoprobe that has been bent, dropped, hit against a hard surface or
compromised in any manner, as damage to the cryoprobe may have
occurred.
Warning
1. while cryoprobe is in use, surgical instruments should be handled with
care to avoid damage to the cryoprobe.
2.Damaged cryoprobe can become inoperable. Thus, avoid pinching, cutting
or pulling it excessively.
3.Do not grasp cryoprobes with auxiliary instruments as this may cause
damage to the cryoprobe shaft.
Caution
Do not move the system when the Dewar contains liquid nitrogen.
Warning
Removing the Dewar, or placing it back within the system after refilling it
must ONLY be done according to system instructions and with the carriage in
the bottom position. If the carriage is not in the bottom position, liquid
nitrogen may spill out.

Insertion of the cryoprobe into the target tissue is performed under the
guidance of an appropriate imaging device and by an authorized practitioner
trained by IceCure Medical.
Warning
The cryoprobe must be IN THE TARGET TISSUE BEFORE starting the freeze
treatment.
Warning

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
Before removing the temperature sensor from the tissue, make sure the
freeze effect has been deactivated and the sensor can be easily withdrawn.
Never use excessive force to extract the temperature sensor.
Warning
DO NOT push the EXTRACTION button when the cryoprobe is not within the
target tissue, as skin burns could occur, and not before the freezing protocol
is completed, unless you want to shorten the procedure due to clinical
judgment.
Warning
Never detach the cryoprobe from the cryohandle if you are not clearly
instructed to unscrew or disengage it.
Caution
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.
Warning
Do not allow any liquid or humidity to enter the cryohandle. Always keep the
cover ON the cryohandle.
Warning
In case of 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.
