1. A method for deploying a device to a distal location across a diseased vessel, comprising:
inserting an expandable protective sheath system into a diseased vessel, wherein the expandable protective sheath system comprises an obturator assembly removably coupled to a distal portion of a sheath, wherein the sheath comprises a lumen, the lumen having a first lumen inner diameter when the sheath is in a collapsed configuration, and wherein the lumen has a second lumen inner diameter when the sheath is in an expanded configuration;
advancing the sheath in the collapsed configuration through the diseased vessel to a desired location;
distally advancing the obturator assembly through the lumen and releasing the obturator assembly from the sheath;
allowing the distal portion of the sheath to expand, wherein the distal portion of the sheath comprises a tubular porous filter mesh coupled to a collapsible hoop structure;
expanding the collapsible hoop structure to fully expand the tubular porous filter mesh to engage a wall of the diseased vessel;
removing the obturator assembly by pulling the obturator assembly proximally through the lumen;
capturing particles in the blood with the tubular porous filter mesh; and
advancing and deploying a device through the sheath.
