Claim 0:
1. A clot treatment system, comprising:
a delivery catheter having a distal end portion;
an outer catheter defining a lumen;
an inner catheter positioned at least partially in the lumen of the outer catheter;
a clot treatment device including a plurality of interconnected struts forming a unitary structure movable between a compressed configuration within the delivery catheter and an expanded configuration outside the delivery catheter, wherein in the expanded configuration the unitary structure includes—
a proximal connection region coupled to the outer catheter;
a proximal conical region extending from the proximal connection region, wherein a first portion of the struts forms first cells in the proximal conical region;
a cylindrical region extending from the proximal conical region;
a distal conical region extending from the cylindrical region, wherein a second portion of the struts forms second cells in the distal conical region, and wherein the second cells are smaller than the first cells; and
a distal connection region extending from the distal conical region and coupled to the inner catheter; and

a distal tip coupled to the inner catheter, wherein the distal tip is configured to abut the distal end portion of the delivery catheter when the clot treatment device is in the compressed configuration within the delivery catheter.
