System, devices and methods for removing obstructions in body lumens

A method of removing a thrombus from a body lumen, comprising:

• selecting a catheter type from a list of selectable catheters presented on a display screen;
• advancing a tip of a catheter into proximity with the thrombus within the body lumen while the catheter is coupled to a pump assembly operating in an aspiration mode, the display screen being operatively coupled to the pump assembly;
• receiving at the display screen a first notification indicating that the thrombus is in a plugged state within the tip of the catheter;
• withdrawing the tip of the catheter and the thrombus in response to receiving the first notification;
• receiving at the display screen, a second notification indicating that the plugged state of the thrombus is compromised;
• and
• stopping withdrawal of the tip of the catheter in response to receiving the second notification.

A method of removing a thrombus via a catheter coupled to a pump assembly, the method comprising:

• receiving at a user input module a user input associated with a selection of the catheter from a list of selectable catheters, the input module implemented in at least one of a memory or a processor coupled to the pump assembly;
• sending, via an aspiration module operably coupled to the pump assembly, a first plurality of signals to the pump assembly to operate the pump assembly in a first aspiration mode during which the pump is operated at a first aspiration speed;
• receiving at the aspiration module a pressure signal associated with a catheter pressure from a sensor of the pump assembly;
• sending to a display screen operably coupled to the pump assembly, a first notification indicating that the thrombus is in a plugged state within a tip of the catheter and prompting a user to manipulate the tip of the catheter on condition that the catheter pressure is below a lower pressure limit for a predetermined time period;
• sending a second plurality of signals to operate the pump in a second aspiration mode;
• and
• sending to the display screen, a second notification indicating that the plugged state of the thrombus is compromised on condition that the catheter pressure rises above the lower pressure limit.
