1. An over-the-wire embolic protection device, comprising:

  • a catheter having a first lumen formed therein;

    a self-expanding filtration element affixed about the distal end of said catheter, formed so as to assume a generally conical shape of preselected maximum diameter when not constrained;

    a sheath, substantially axially aligned with said catheter, longitudinally shiftable relative to said filtration element and dimensioned to constrain said filtration element to a reduced diameter; and

    an inner member disposed within said first lumen of said catheter so as to be longitudinally shiftable therein, said inner member having a lumen formed therein dimensioned to accommodate a guidewire and wherein said inner member is attached to said sheath at its distal end while its proximal end extends towards the proximal end of the device.
