Patent ID: 7972356

Claim:
A system including an embolic filtering device used to capture embolic debris in a body vessel, the system comprising: a guide wire having a pair of stop fittings attached thereto; an expandable cage including: a proximal circumferential member adapted to move between a collapsed position and an expanded position, the proximal circumferential member forming a closed loop which includes a plurality of bending regions formed therein; a distal circumferential member adapted to move between a collapsed position and an expanded position, the distal circumferential member forming a closed loop which includes a plurality of bending regions formed therein, the proximal circumferential member being connected to the distal circumferential member by at least one connecting strut, the at least one connecting strut being attached at one of the bending regions of the proximal and distal circumferential members; a proximal strut having one end attached to the bending region of the proximal circumferential member and another end attached to a collar disposed between the pair of stop fittings on the guide wire; a distal strut attached to the bending region of the distal circumferential member; and a filter member attached to the expandable cage.
