You must NOT allow the freeze process to start before the cryoprobe active
area is actually within the target tissue.
Warning
Cryoprobe, introducer, temperature sensor and holder materials are not
compatible with magnetic resonance imaging
Before activating the freeze cycle, insert the cryoprobe into the target tissue according to
the following steps:
1.
Plan the trajectory of the cryoprobe prior to placement. The center of the cool
zone shall be along the longest dimension of the target tissue (if required parallel
to the chest wall in breast applications).
2.
In percutaneous procedures, insert cryoprobe under ultrasound guidance or
other appropriate imaging guidance:
•
Confirm longest dimension of the target tissue
•
Perform a 3 mm skin incision (for example using #11 blade)
•
Position the tip of the cryoprobe minimally 4 mm beyond the distal edge
of the long axis of the target tissue
3.
When an introducer to guide the Cryoprobes to the tissue location is used, an
introducer with tight dimensions should be used. The cryoablation may be
affected by the use of an introducer that is too big and create an air barrier
between the freezing power of the cryoprobe and the tissue, inject 5cc of sterile
saline or water into the introducer lumen to improve heat exchange between the
cryoprobe and the tissue, if too big Introducer was chosen.
For optimal cryoprobe positioning please note the following:
