percutaneous procedures under reduced mechanical stress. It is preferred to use the
adapted lengths according to the superficiality of the lesions.
Select the cryoprobe based on ice ball size you want to obtain and the cooling zone
location as defined in the table above.
Always monitor the ice ball engulfment with appropriate imaging modality.
Marks on the cryoprobe shaft aid in determining the depth of cryoprobe insertion. The
first mark (closest to the tip) is thicker and represents the minimum insertion depth of the
cryoprobe for a percutaneous procedure. Before starting the freezing procedure, the user
must verify that this mark is fully inserted into the skin.
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.
Warning
Cryoprobe, introducer, temperature sensor and holder materials are not
compatible with magnetic resonance imaging.
Introducer
The needle guide, named Introducer consists of two main parts made of stainless steel:
Mandrel
–
a needle attached to a standard female Luer
Cannula
–
a fitting trocar attached to a standard lock hub
The notch on the mandrel is visible under imaging systems and facilitates positioning of
the introducer inside the target tissue.
