Cryogenic Medical System


Kryos Technologies approached Optima to design a cryogenic cancer reduction machine. Cryosurgery, the application of extreme cold to destroy abnormal or diseased tissue,  is used to treat tumours within the body.

For internal tumours, liquid nitrogen or argon gas is circulated through a hollow instrument called a cryoprobe, which is placed in contact with the tumour either during surgery or through the skin. A ‘ball’ of ice crystals forms around the probe, freezing and destroying nearby cells. Sometimes more than one probe is used to deliver the liquid nitrogen to various parts of the tumour.  After cryosurgery, the frozen tissue thaws and is either absorbed by the body or it forms a scab on the skin.

Optima’s design process involved targeted research into various manufacturing techniques to suit different levels of production, styling and aesthetics and the delivery of cryogenic liquids in a safe environment. Advice from senior consultants was also fed into the final concept design, which is   currently undergoing detailed product review with the hope of obtaining investment by leading medical device manufacturers.
