1. A method of positioning a filter embolic protection device in an aorta, the method comprising:
- advancing the filter embolic protection device, the filter embolic protection device comprising;
a first elongate, tubular body, having a proximal end, a distal end and a central lumen extending therethrough;
a second tubular body, extending through the central lumen; and
a filter assembly carried by the second tubular body, the filter assembly comprising a plurality of filter portions joined together about a longitudinal axis;
deploying the filter assembly;
advancing a catheter, the catheter comprising a tubular body;
positioning the catheter and the filter assembly such that the filter assembly forms a seal with the catheter to prevent substantially all debris from flowing past the filter assembly when the catheter is positioned between the filter assembly and a vessel wall.
