Abstract:
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 first signal that is a distal pressure or flow rate; a proximal sensor device affixed to the elongate catheter body proximal the distal sensor device and configured to be positioned in a patient's systemic vasculature, wherein the proximal sensor device generates a second signal that is a proximal pressure or flow rate; a controller in communication with the proximal and distal sensor devices, and a 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 perform an analysis comprising comparing: the first and second signals generated from the distal and proximal sensor devices, and cause an (a) increase in fluid delivery to the at least one lumen from the fluid delivery device if the distal pressure or flow rate is at a first predefined limit greater than the proximal pressure or flow rate, or (b) decrease in fluid delivery to the at least one lumen from the fluid delivery device if the distal pressure or flow rate is at a second predefined limit lower than the proximal pressure or flow rate.
