Claim 12:
13. A method of treating clot material in a blood vessel, the method comprising:
advancing a clot treatment device in a low-profile state through a lumen of a guide catheter, wherein the clot treatment device includes a mesh structure;
at least partially expanding the clot treatment device within the blood vessel from the low-profile state to a deployed state, wherein, in the deployed state—
the mesh structure includes at least three treatment portions spaced apart from one another,
individual ones of the treatment portions include a proximally-facing curved portion and a distally-facing curved portion, and
the proximally-facing curved portion and the distally-facing curved portion have the same radius of curvature;

expanding a funnel member within the blood vessel proximal of the clot material and such that the funnel member has a diameter that is less than a diameter of the blood vessel;
engaging the clot treatment device with the clot material;
retracting the clot treatment device and a portion of the clot material into a distal portion of the guide catheter; and
inhibiting, with the funnel member, the clot material from moving proximally through the blood vessel past the distal portion of the guide catheter during retraction of the clot treatment device and the portion of the clot material into the distal portion of the guide catheter.
