Abstract: Medical devices and methods for using medical devices are disclosed. An example medical device may include an open-irrigated ablation catheter. The open-irrigated ablation catheter may include a catheter body, an electrode tip body with irrigation ports at a distal end, and a coolant conduit. The distal end of the coolant conduit may extend into a proximal portion of the electrode tip body. Fluid flow from the coolant conduit may be diverted proximally and/or towards the wall of the electrode tip body by one or more openings proximal of a closed distal end of the conduit or by a structure blocking and diverting flow from an open distal end of the conduit.
