Aspiration monitoring system and method
In one embodiment, system for real time monitoring of catheter aspiration includes a housing having a first port adapted for connection to a vacuum source and a second port adapted for 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. In another embodiment, the system for real time monitoring of catheter aspiration further includes a vacuum source for connection to the first port and an aspiration catheter having an aspiration lumen for connection to the second port.
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.
2. The self-contained monitoring device of claim 1 , wherein the pre-set threshold is between about 700 pascal and about 1700 pascal.
3. The self-contained monitoring device of claim 2 , wherein the pre-set threshold is between about 1000 pascal and about 1300 pascal.
4. The self-contained monitoring device of claim 3 , wherein the pre-set threshold is about 1158 pascal.
5. 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 communication device is configured to generate a second type of alert in response to the deviation comprising a plurality of increases and decreases of vacuum pressure no longer being measured by the measurement device.
