17. A method for retrieving an embolic protection device, comprising the steps of:
-
providing a guidewire into a vascular region of a patient, the guidewire having a distal end and an embolic protection device disposed at the distal end;
providing a retrieving catheter comprising an inner shaft and an outer sheath, the outer sheath including a side opening;
wherein the inner shaft includes a tubular member having a proximal region, a port disposed near the side opening in the outer sheath, a distal region, and a tip disposed at the distal region; and
wherein the inner shaft further comprises a plurality of flush holes;
placing the inner shaft in a first position relative to the outer sheath;
advancing the catheter over the guidewire to a position near the embolic protection device;
locking the guidewire relative to the inner shaft;
shifting the inner shaft and the guidewire to a second position relative to the outer sheath, wherein shifting to the second position results in at least a portion of the embolic protection device being disposed within the outer sheath; and
removing the catheter and guidewire from the vascular region. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method for delivering an embolic protection device, comprising the steps of:
-
providing a delivery catheter comprising an inner shaft and an outer sheath, the outer sheath including a side opening;
wherein the inner shaft includes a tubular member having a proximal region, a port disposed near the side opening of the outer sheath, a distal region, and a tip disposed at and a plurality of openings beside the port,configuring the inner shaft such that at least a portion of the tip extends distally out of a distal end of the outer sheath;
disposing a guidewire within a portion of the inner shaft, the guidewire including an embolic protection device coupled thereto, wherein at least a portion of the embolic protection device is collapsed within the outer sheath;
advancing the catheter through a vascular region of a patient to a desired location;
shifting the outer sheath proximally relative the inner shaft and the guidewire such that the embolic protection device emerges from the distal end of the outer sheath; and
removing the delivery catheter from the vascular region of the patient.
