Claim Text:
1. A clot removal system, comprising: an elongated tubular sheath; and an elongated tubular catheter received within the sheath, wherein a distal segment of the catheter is split into a plurality of catheter wall segments, wherein each of the wall segments has a pre-shaped curved configuration and defines at least one scraping edge; wherein the clot removal system has a transport configuration in which the distal segment of the catheter is axially aligned with a distal segment of the sheath and the wall segments are urged against the pre-shaped curved configuration by a lumen wall of the sheath, and a deployed configuration in which the distal segment of the catheter is advanced distally beyond the distal segment of the sheath and the wall segments conform to the pre-shaped curved configuration; an elongated wire guide received within the catheter and having a distal segment extending beyond the distal segment of the catheter; wherein a distal tip of each wall segment is less stiff than a remaining portion of the wall segment; wherein the catheter is configured for rotation about a longitudinal axis; and wherein the catheter has a tapered distal segment, and a portion of the distal segment is shaped as a dilator and protrudes distally beyond a distal end of the sheath in the transport configuration.
