New Product Development
for Cryosurgery
Smallest diameter cryoablation needle available
Galil Medical is in the forefront of new product development for cryosurgery (freezing) bringing precision instruments to the hands of dedicated and highly trained cryo specialists. Realizing the patient benefit of percutaneous procedures, Galil Medical’s patented 17-gauge cryoablation needle technology has aided in the realization of truly minimally invasive ablation treatment.
Galil Medical developed patented 17-gauge needle technology for use in a range of cryotherapy treatments. Technological and manufacturing advances have allowed this progressive decrease in needle diameter to a size comparable to a biopsy needle.
In the trained physician’s hand, these ultra-thin cryoablation needles enable simple percutaneous (through the skin) insertion, while patients benefit from quick recovery in a minimally invasive procedure. The physician inserts the needle directly into the target tissue with minimal force, making the procedure much easier to perform as well as shortening the overall duration of the procedure.
For minimally invasive surgery for prostate cancer treatment, Galil Medical offers a unique template, based on the familiar brachytherapy template, for easy insertion according to defined coordinates. For kidney cancer treatment, clinical studies have shown reduced potential damage to the kidney tissue and a decreased risk of bleeding with this technology.
17-gauge Family
Galil Medical continuously strives to improve cryoablation procedure precision and control. Innovative small diameter needles have been shown to minimize the risk of damage to adjacent tissue during cryosurgical ablation.
• The IceSeed™ needle creates a small, round shaped iceball for targeting small tumors. When multiple needles are used in predetermined configurations, ablation can be performed on larger tumors.
• The IceRod™ needle creates a large, oval shaped iceball for prostate cryotherapy treatment, as well as target tissue that requires a larger lethal freeze zone. Galil Medical, in conjuction with physicians performing cryo procedures, has developed a set of standard configurations for repeatable prostate procedures.
• The IceBulb™ needle creates a large, pear-shaped iceball for targeted treatment of large tumors.
i-Thaw™
The newly released i-Thaw™ cryoablation needles use low pressure Argon to thaw, eliminating the need for Helium tanks. Understanding that space and cost efficiency is a priority for surgical procedures, the Presice™ Cryoablation System supports a full range of needles in both Helium and i-Thaw™ for prostate cryoablation and kidney cryoablation procedures.
Lethal iceballs
The smallest diameter cryoablation needle on the market, 17-gauge cryoablation needles bring a new level of precision to cryotherapy treatments for prostate and renal cancer, liver metastasis, and other tumors. Each needle has been designed to create a defined iceball size and shape to match a specific clinical application and allowing the flexibility to sculpt ice coverage of organs or tumors of various shapes.
Every iceball is comprised of an inner lethal freeze zone and an outer zone with higher temperatures. The temperature at the outer zone does not cause damage to healthy tissue. Vigorous laboratory testing is utilized to map the lethal freeze zone as well as the outside iceball dimensions, providing the physician with a precision tool for cryotherapy ablation. |
