The present invention relates to catheters in general and more particularly to improvements in so-called "irrigated ablation catheter" that may be used in mapping and ablation procedures of tissue, preferably heart tissue in the treatment of cardiac arrhythmia.The present invention is directed irrigated ablation catheter comprising an elongated catheter shaft (4), a deflectable section (3) distal to the catheter shaft, an ablation catheter tip (1) distal to the deflectable section. The ablation catheter tip comprises an irrigation fluid flow distributor (10) having a distal end (16) and a proximal end (15) whereby the irrigation flow distributor has an inner channel (11) and an outer channel (12) whereby the inner channel leads distally to the outer channel. The outer channel has a helical shape and is in direct contact with a plurality of irrigation fluid exit ports, said exit ports being arranged such that they follow the spiral course of the outer channel.
