Abstract: An embolic protection filter for collecting particulate debris in a body lumen and method of making same. The embolic filter includes a spirally cut outer tubular member disposed about a spirally cut inner tubular member, the spiral cuts having opposite chirality. The embolic filter is transformable between a collapsed configuration and an expanded configuration wherein filter openings are defined by intersections of the spiral cuts. The spiral cuts may have a variable pitch for sizing the filter openings to be larger in a proximal portion of the filter for receiving embolic debris, and smaller in a distal portion of the filter for retaining embolic debris within the filter. In an embodiment of the invention, the length of the expanded configuration is substantially equal to the length of the collapsed configuration.
