Claim 17:
18. An aspiration catheter system, comprising:
an aspiration catheter defining a lumen and having a proximal end portion; and
a hemostasis valve comprising—
a support;
an actuator having at least a first member movably coupled to the support;
a collapsible tubular sidewall defining a lumen carried by the support, wherein the lumen of the tubular sidewall is selectively fluidly couplable to the lumen of the aspiration catheter;
a filament formed in a loop around the tubular sidewall, the filament having at least a first end portion extending away from the loop to the first member; and
a spring configured to move the first member in a direction that pulls the first end portion away from the tubular sidewall, reducing a diameter of the lumen in response to reducing a diameter of the loop to fluidly decouple the lumen of the tubular sidewall from the lumen of the aspiration catheter.
