Claim Text:
1. A self-contained monitoring device for real time monitoring of catheter aspiration, configured for removable connection in between an aspiration catheter and a vacuum source, comprising: a housing having a first port adapted for detachable connection to a vacuum source and a second port adapted for detachable connection with an aspiration catheter; a pressure sensor in fluid communication with an interior of the housing; a measurement device coupled to the pressure sensor and configured for measuring deviations in fluid pressure; and a communication device coupled to the measurement device and configured to generate an alert signal when a deviation in fluid pressure measured by the measurement device exceeds a pre-set threshold, wherein the communication device is configured to generate a first type of alert in response to a deviation measured by the measurement device comprising a plurality of increases and decreases of vacuum pressure, and wherein the plurality of increases and decreases of vacuum pressure comprises a baseline vacuum pressure and a peak vacuum pressure, and wherein the pre-set threshold is compared to a difference between the peak vacuum pressure and the baseline vacuum pressure.
