Claim:
1. An irrigated catheter ablation system comprising: an irrigated ablation catheter assembly including: a fluid source connected to or in operative communication with the catheter assembly; an energy source connected to or in operative communication with the catheter assembly; and an irrigation temperature control mechanism in communication with the fluid source and the energy source, wherein the irrigation temperature control mechanism controls or regulates irrigation flow of fluid from the fluid source in response to temperature measurements received from a temperature sensor, wherein at least a portion of the temperature sensor is disposed within the outer body portion of the electrode, wherein the flow of fluid during ablation includes flow that alternates between a maintenance flow rate having a nonzero flow of fluid and an amplified flow rate having a flow of fluid that is greater than the maintenance flow rate, and wherein the energy source is configured to provide ablation energy for the electrode and wherein the irrigation flow of fluid includes a variable delay between the start of the provision of energy by the energy source and the initial start of the flow of fluid.
