Abstract

A catheter tip is disclosed comprising a tip electrode comprising a ledge feature, and a center cavity and a manifold assembly comprising a fluid lumen manifold and a stop tube. The stop tube can be coupled to the fluid lumen manifold and configured to abut the ledge feature such that a distal end of the fluid lumen manifold extends a pre-determined distance into the center cavity of the tip electrode. The fluid lumen manifold can comprise a plurality of sideholes which can be sized and configured to distribute an irrigant to the tip electrode. The catheter tip can comprise a flexible tip electrode.
