In animals cryosurgery is ideal for the removal of a variety of irritating leasions and tumours, and for patients unsuitable for general anaesthesia, and it can be curative in many cases.  Cryosurgery has been around for about 100 years and applies intense cold resulting in the death of the target tissues while temporarily numbing the surrounding sensory nerves causing minimal pain and discomfort during the procedure, and it is largely a bloodless procedure. Its mechanism can be divided into 3 phases:

  • Phase 1:  Instantaneous action of cold causing extracellular water to crystallize, leading to localised hyperosmolity and leakage of intracelluar water with rise in toxic electrolytes, protein denaturation and cellular damage.
  • Phase 2:  Takes place a few hours post-application and is characterised by vascular stasis leading to thrombosis, localised ischaemia, modification in pH and cellular death.
  • Phase 3:  The last phase starts several days after application and consists mainly of a localised increase in immune response.

The proven targeted action of cryosurgery for the destruction of epithelial cells makes it a practical method for removal of certain cutaneous growths and lesions in the mucosa. It is also used in opthalmological procedures.

The CryOmega® is a low-cost disposable device intended for the surgical destruction of target tissue by applying cryogenic gases at extreme low temperatures. It can be used in any medical setting.
  This simple cryosurgical device delivers a direct spray of liquid nitrous oxide at -89ºC to the treatment site as a simple, hassle-free procedure with no need for extra accessories or replacement cartridges. Each device delivers around 50 five-second treatments. It is recommended for small lesions no larger than 1cm across and no deeper than 5mm.
  Types of lesions that can be treated with CryOmega®:  
  • Keloids
  • Warts
  • Granulomas
  • Haemangiomas
  • Basal cell carcinoma
  • Circumanaloma
  • Lick dermatitis
  • Eye-lid tumours

The benefits of CryOmega® over other forms of cryotherapy:

    • Can be used in any clinical setting.
    • As effective as liquid nitrogen without high costs, cumbersome  equipment, and maintenance costs.
    • No risk of flammability.
    • No replacement cartridge required, repairs, or maintenance.
    • Easy operation and long shelf-life. Unused, the shelf-life is many years. Once activated the shelf-life is 6 months or more.

The CryOmega® device is:

  • Effective: Continuous direct spray of liquid nitrous oxide (-89°C) produces clinically effective freezing. Pinpoint precision prevents destruction of healthy tissue.
  • Convenient:  Activate once and the device is ready for use. No additional accessories needed.
  • Economical: Each unit has up to 300 secs/5 mins of spray time and can be used for multiple procedures (e.g. 60 x 5 second treatments). 
  • Disposable:  Simply dispose of the entire unit when the cartridge is empty.
