A low profile emboli capture device is provided for use in angioplasty and other intravascular procedures. A standard guidewire is utilized having a reduced cross-sectional area formed near its distal end. A filter and self-expanding stent are packaged on the reduced cross-sectional area of the guidewire. A movable sleeve extends over the guidewire and holds the self-expanding stent and filter in their retracted positions while the device is being positioned in the artery. The sheath is moved relative to the self-expanding stent and filter, whereupon the self-expanding stent and filter become deployed.
