Proof of concept percutaneous treatment system to enable fast and finely controlled ablation of biological tissue.

A prototype system has been developed for producing controllable ablation of spherical lesions with a diameter of up to 2 cm. The system is based on a solid-state energy source operating in the super high frequency (SHF is defined as being a frequency of between 3 and 30 GHz) region of the electromagnetic spectrum. Results obtained from preliminary tissue testing, performed on morbid tissue samples prepared in a laboratory environment, show repeatability in terms of shape and size of ablation, and demonstrate the ability to produce controlled ablation in morbid liver and kidney models.
