1. A catheter device, comprising:

  • an elongate catheter body, comprising a distal end and a proximal end;

    at least one lumen extending from the proximal end to the distal end of the elongate catheter body;

    a distal sensor device affixed to the elongate catheter body substantially near the distal end, wherein the distal sensor device generates a signal that is a distal pressure;

    a controller in communication with the distal sensor device, anda fluid delivery device in fluid communication with the at least one lumen and in electrical communication with the controller;

    wherein said catheter device is a cerebral catheter device configured to be inserted into cerebral arteries;

    wherein the controller is configured to store one or more signals collected over time as historical signals corresponding to one or more historical distal pressure measurements and to perform an analysis comprising comparing;

    the signal generated from the distal sensor device to the historical signals and determine whether the first signal is greater than or lower than at least one of the historical signals, and cause an(a) increase in fluid delivery to the at least one lumen from the fluid delivery device if the distal pressure is at a first predefined limit greater than at least one of the historical distal pressures, or(b) decrease in fluid delivery to the at least one lumen from the fluid delivery device if the distal pressure is at a second predefined limit lower than at least one of the historical pressures.
