Abstract

An irrigation catheter device, in particular an ablation catheter, including a catheter body in which a central lumen extends from a proximal region into a distal region, wherein a large number of irrigation channels extend away from the lumen, the outlet openings of which out of the catheter body are distributed across the distal end region thereof, wherein sensors are assigned to the central lumen and/or the individual irrigation channels for pressure measurement and/or to measure the flow velocity, to which evaluation means are connected, which are designed to determine the open or closed state of a portion of the irrigation channels on the basis of measured values registered by the sensors.
