Therapy apparatus for the treatment of pathological tissue with a catheter

摘要

A therapy apparatus for the treatment of pathological tissue with focused ultrasound waves, has a catheter introducible into the body of a living subject to be treated and having at least one pressure sensor disposed at the region of its distal end. A control unit to which the output signal of the pressure sensor is supplied generates an alarm signal if the level of the output signal of the pressure sensor exceeds a limit value, thereby minimizing the risk of damaging healthy tissue.
