Devices, methods, and systems provide an embolism deflecting device, methods for deflecting or diverting emboli away from critical locations in the body, and systems therefor. Embodiments of the embolism deflecting device comprise an embolism detector, a diverter controller operable for determining the presence of emboli from a target input from the embolism detector, and an embolism diverter operable by the diverter controller to deflect, divert, redirect, etc., emboli away from the critical body location on the detection thereof.
