Abstract: Catheter devices and methods are disclosed and described. A catheter device (100) can include a longitudinal lumen (104) and having a proximal end (104a) and a distal end (104b). The distal end (104b) is capable of insertion into at least the internal carotid artery. The catheter device (100) can include an occlusion balloon (120b) connected to the distal end (104b) and operable to occlude blood flow in a blood vessel (102) by inflation and deflation using a pressurization fluid. The catheter device (100) can include a pressure sensor (110b) associated with the distal end (104b) and operable to measure blood pressure data from at least one of a downstream (103b) and upstream (103a) location of the occlusion balloon (120b) and transmit the blood pressure data to a controller (150). The occlusion balloon (120b) can be operable to inflate or deflate based on inflation control information. The catheter device (100) can be used to treat cerebral thrombectomy in a subject.
