Claim 16:
17. A clot treatment assembly, comprising:
a first elongate shaft defining a lumen and having a distal portion a proximal portion;
a funnel coupled to the distal portion of the first elongate shaft;
a hub fixedly coupled to the proximal portion of the first elongate shaft, wherein the hub includes a stop portion;
an aspiration source;
a fluid path extending from the distal portion of the first elongate shaft, through the lumen of the elongate shaft, through the hub, and to the aspiration source; and
a second elongate shaft coaxial with the first elongate shaft, wherein—
the second elongate shaft includes a distal portion and a proximal portion,
the second elongate shaft is axially movable relative to the first elongate shaft in a single direction between a first position and a second position,
the stop portion of the hub is configured to inhibit further movement of the second elongate shaft in the single direction past the second position,
in the first position, the distal portion of the second elongate shaft extends over the funnel to radially constrain the funnel in a constrained configuration, and
in the second position, the funnel is unconstrained by the distal portion of the second elongate shaft and configured to self-expand to an expanded configuration.
