1. A prosthetic heart valve delivery catheter having integrated embolic protection, said catheter comprising:
a catheter shaft having a distal portion;
an expandable balloon on the distal portion of the catheter shaft;
a prosthetic valve disposed on the expandable balloon on the distal portion of the catheter shaft; and
an embolic filter disposed on the distal portion of the shaft at a location proximal of the prosthetic valve, said embolic filter having a collapsed configuration and a deployed configuration wherein an outer periphery of the filter is configured to contact a blood vessel wall;
wherein the embolic filter comprises a cylindrical wall having an open distal end unattached to the shaft and a closed proximal end sealing coupled to the catheter shaft, wherein a proximal region of the cylindrical wall is movably everted and allows the open distal end to axially translate relative to the catheter shaft while the closed proximal end remains stationary relative to the catheter shaft.
