An irrigated ablation catheter includes a shaft having a proximal end, a distal end, and an irrigation lumen therein. The catheter further includes an electrode assembly coupled to the distal end of the shaft. The electrode assembly includes an ablation electrode and a manifold. The manifold is coupled to each of the distal end of the shaft and the proximal end of the electrode. At least a portion of the manifold is constructed of a flexible material to allow the electrode assembly to deflect. The manifold includes a body, an inner cavity within the body configured for fluid communication with the irrigation lumen, and an irrigation port also within the body and configured for fluid communication with the inner cavity. The irrigation port extends from the inner cavity to the outer surface of the body, and is configured to allow for an irrigating fluid to be distributed from the manifold. |
