Fluid sensor for ablation therapy

A method of monitoring fluid delivered during ablation therapy, the method comprising:

• deploying, via a trigger coupled to a housing comprising a handle, a needle from a catheter that houses at least a portion of the needle into a target tissue, wherein the housing is coupled to the catheter;
• delivering ablation energy via the needle to ablate at least a portion of the target tissue;
• delivering the fluid from a pump to the target tissue via the catheter;
• providing a sensor between the pump and the target tissue, wherein the sensor is located within at least one of the catheter or the housing;
• detecting, by the sensor, a fluid parameter indicative of at least one of flow or pressure of the fluid;
• automatically stopping, by a processor, delivery of the ablation energy in response to the detected fluid parameter exceeding a threshold;
• and
• automatically allowing, by the processor, subsequent redelivery of the ablation energy only after the processor receives user input comprising an adjustment of at least one of a flow rate of the fluid and a power of the ablation energy.
