CRYOABLATION
PRODUCTS
SeedNet™ System
SeedNet™ System with
Ultrasound or CT Imaging Guidance and Temperature
Monitoring
The SeedNet™ System is intended for the cryogenic destruction of tissue during minimally invasive surgical procedures.
The SeedNet™
Cryoablation System features Galil Medical
patented freezing technology and 17-gauge cryoablation
needle design. An easy-to-use interface, versatile
capabilities, and easy mobility makes it suitable
for use in both inpatient and outpatient settings.
The SeedNet™
system is used by urologists performing minimally
invasive prostate
cancer treatments and kidney
cancer treatments, as well as for Interventional
Radiology or general surgery treatments including
liver cancer ablation, lung cancer ablation, and
bone cancer ablation.
Galil Medical cryotherapy provides high technology precision for physicians to perform minimally invasive procedures as an alternative to surgical excision or other ablative technologies. Integration with ultrasound or CT enables a high level of control for needle placement and positioning, iceball formation, and the freezing process. Imaging guidance combined with real-time temperature monitoring allows treatment close to susceptible organs for procedure control.
Presice™ Cryoablation System
The Presice™
Cryoablation System is based on the same patented
freezing technology as the SeedNet™
system, but goes a step beyond by providing
tools specially designed for the urologist performing
prostate
cryoablation and kidney
cryoablation. The IceVue™
Planning software provides the urologist with
a user-friendly interface to create a preoperative
plan and simulate the outcomes of the procedure.

Cryoablation system and IceVue™
Planning Software.
The Freezing Process
The SeedNet™
System is operated by using high-pressured
Argon and Helium gases, supplied from an external
gas source. SeedNet™
uses compressed Argon gas through the Joule-Thomson
effect to produce extremely low temperatures.
The freeze and subsequent thaw processes are administered
via patented, ultra-fine (1.47 mm diameter) cryosurgical
needles, the exact positioning and configuration
of which is determined by the physician.
As the gas passes through the cryoablation needles, the tip of the needle is cooled, forming an iceball, which engulfs the tumor and destroys the tissue. The user-friendly graphical interface allows the physician to immediately switch from the freezing to the thawing process, control the gas flow to the needles and monitor temperatures in real-time.
17-gauge Cryoablation Needles
A full range of small diameter 17-gauge
cryoablation needles are available for easy,
percutaneous insertion during minimally invasive
surgery. The needles are inserted using imaging
guidance such as ultrasound or CT, enabling accurate
needle placement and precise therapy to the tumor.
System compatibility with ultrasound and CT imaging
modalities enables a high level of control for
cryosurgery. Read about the MRI
SeedNet™ system for performing cryoablation
in MRI-guided surgery.
The physician uses a configuration of needles to sculpt a precise freeze zone to match the shape and size of the target tumor. CT-compatible needles include 90 degree and straight handles for versatile access. The echogenic tip is clearly visible under ultrasound.
Temperature Monitoring
Thermal
sensors (TS) may be used by the surgeon or
IR to obtain additional information about the
temperature field at chosen tissue locations,
both within and surrounding the frozen tissue.
Usually these thermal sensors are inserted at
strategic locations to confirm that the boundaries
of the tumor have been frozen and that adjacent
healthy tissue has not been damaged.
SeedNet™ 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.
