FIELD: medicine.
SUBSTANCE: invention relates to medical equipment, namely to devices for tissue ablation. Device contains catheter with energy irradiator and photoacoustic sensor. Energy irradiator emits a ray into target section of tissue to form in it section of affection. Inflatable balloon, surrounding energy irradiator and photoacoustic sensor is fixed to catheter. Balloon is filled with optoacoustic conducting medium. Energy irradiator also emits a photoexciting ray into target section of tissue. Photoacoustic sensor determined photoacoustic response of tissue. System for ablation contains system of ablation control and device for ablation, with energy irradiator controlling system of ablation control for emission of a tissue-excising ray, and emission of a photoexciting ray. Device for ablation therapy of tissue, in addition, contains controllers, controlling energy irradiator, and monitor.
EFFECT: application of the invention makes it possible to determine formation of section of ablation affection in real time by means of photoacoustic effect.
