In 5 accordance with one embodiment, an aspiration system includes an aspiration line having distal and proximal ends and an aspiration port defined in the distal end a fluid transport device operatively coupled to the proximal end of the aspiration line, To measure occlusion within the line, first and second temperature sensors are utilized, the second sensor being operatively coupled to the aspiration line at an upstream point to the first 10 sensor. The temperature differential between the two sensors can provide an indication of the onset, presence, and/or elimination of an occlusion.
