Aspiration monitoring system and method
First Claim
1. A system for removal of blood or thrombus comprising:
- a vacuum source;
an aspiration catheter having an elongate shaft including an aspiration lumen having a proximal end and a distal end, the proximal end configured to couple to the vacuum source, the distal end having an orifice;
an elongate member configured for placement through the aspiration lumen, the elongate member having a proximal portion configured to extend from the proximal end of the aspiration lumen;
a rotating device configured to couple to the proximal portion of the elongate member, the rotating device comprising a body and a rotation element, the body configured to be gripped by a user and the rotational element configured to rotate the elongate member when the rotating device is coupled to the elongate member; and
a self-contained monitoring device for real time monitoring of catheter aspiration, configured for removable connection in between the aspiration catheter and the vacuum source, comprising;
a housing having a first port adapted for detachable connection to the vacuum source and a second port adapted for detachable connection with the 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.

Abstract
A system for removal of blood or thrombus includes an aspiration catheter having an elongate shaft including an aspiration lumen having proximal end configured to couple to a vacuum source, and a distal end having an orifice, an elongate member configured for placement through the aspiration lumen and having a distal portion including a disruption element configured to disrupt thrombus within the aspiration lumen, and a monitoring device configured for removable connection in between the aspiration catheter and the vacuum source, and including a housing, 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.
