An irrigated ablation catheter provides improved distribution of irrigation fluid across its tip electrode surface resulting in improved cooling and flushing of blood and proteins from the tip region. The basis of trust for the computer system is established by an encryption coprocessor and by code which interfaces with the encryption coprocessor and establishes root of trust metrics for the platform. A pulsation sensor is placed in the lateral piping, to measure pulsation within the piping. All components of the system are easy to install due to the modular design and conventional power sources.
