1. An embolic protection device, said device comprising:
- a cylindrical porous mesh filter having an open distal end, a closed proximal end, an interior including a collection chamber, a radially collapsed delivery configuration, and a radially expanded configuration; and
a sheath having a distal end, a proximal end, and an inner lumen extending from the proximal end to the distal end, said distal end of the sheath being fixedly attached to a proximal end of the cylindrical porous mesh filter and said inner lumen being configured to allow passage of a catheter therethrough;
wherein the closed proximal end of the cylindrical porous mesh filter is fixedly attached to the distal end of the sheath and has a radially expandable port configured to receive catheters of different diameters therethrough; and
wherein a first catheter may be introduced into the interior of the cylindrical porous mesh filter through the inner lumen of the sheath and a second catheter may be introduced into the interior of the cylindrical porous mesh filter though the expandable port.

Abstract
The embolic protection device comprises an embolic filter attached to an inner sheath. The embolic filter includes at least a first catheter access port and a second catheter port. At least the first catheter port will typically be radially expandable to receive catheters of different diameters and will be located at an atypical end of an aero conical structure at a downstream end of the filter.
