The present invention relates to a catheter (20) adapted for open-loop irrigated ablation such as RF ablation of a tissue (40). Said
catheter has a distal tip (22) with an ablation entity (15) adapted for performing ablation of the tissue an irrigation hole (21) and
an ultrasound transducer (5) adapted for transmitting and/or receiving ultrasonic waves. The ultrasound transducer is disposed
behind or in the irrigation hole of the catheter so as to allow an irrigation fluid to flow out of the irrigation hole and so as to allow
