Abstract

A dedicated distal protection guidewire having proximal and distal stops disposed about an elongated core wire is disclosed. A guidewire in accordance with the present invention includes an elongated core wire having a relatively stiff proximal section and a relatively flexible distal section, a distal stop disposed about a portion of the elongated core wire, and a proximal stop disposed about a portion of the elongated core wire proximal the distal stop. The distal stop may be formed from an enlarged outer diameter portion on the elongated core wire, or may be formed from an object disposed about and secured to a portion of the elongated core wire. The proximal stop may include an O-ring disposed within a recessed surface on the elongated core wire, or an annular ring having several circumferentially disposed notches. In one exemplary embodiment, a distal protection guidewire may include a proximal stop comprising a first tubular member, a second tubular member, and a plurality of expandable struts actuatable between a collapsed position and a deployed position.
