摘要：
A system for ablating tissue, said system comprising: an elongated rod (18) having a proximal portion, a distal portion and a longitudinal axis； a housing (16) next to the distal end of the elongated rod； an ultrasound transducer (12) coupled to the distal portion of the elongated rod and disposed in the housing, wherein the ultrasound transducer is adapted to supply a beam (20) of ultrasound energy to ablate a target tissue； a barrier arranged between one face of the ultrasound transducer and adjacent blood or tissue, wherein the barrier allows the ultrasound energy beam to ablate the target tissue without contact between the ultrasound transducer and the target tissue, and where the barrier comprises a fluid flow (28) beyond the ultrasound transducer to prevent blood from clotting on it； a reflective element (22) operatively coupled with the ultrasonic transducer, the reflective element redirecting the beam of ultrasound energy emitted from the ultrasonic transducer to a desired direction or a pattern, wherein the reflective element is configured to direct the beam of ultrasonic energy through a side wall of the housing to form a continuous lesion in the target tissue； a sensor (40) next to the ultrasonic transducer or the ultrasonic transducer as a sensor, wherein the sensor is adapted to detect characteristics of the ablated tissue, the non-ablated or target tissue； and a processor configured to control the ultrasonic energy supply from the ultrasonic transducer based on the information received from the sensor and to control the fluid flow of the barrier by increasing or reducing the fluid flow based on the information received. of the sensor.Un sistema para ablacionar tejido, comprendiendo dicho sistema: un vástago alargado (18) que tiene una porción proximal, una porción distal y un eje longitudinal； un alojamiento (16) junto al extremo distal del vástago alargado； un transductor de ultrasonidos (12) acoplado a la porción distal del vástago alargado y dispues
