Abstract
A support 103 for an embolic protection device comprises round wires 116 which may form one or more support hoops for a filter body. The circumferential hoop formed by the wires 116 ensures that in the expanded position, the filter body 102 will be supported by the support frame 103 in circumferential apposition with the interior wall of the vasculature. The wires 116 may have a strain distributing linkage element in the form of a loop 120 in. The loop 120 acts as a diameter or circumference adjuster allowing an embolic protection device to adapt to different vessel contours and sizes whilst maintaining apposition with the vessel wall. The strain relieving geometry of the loops enhances the compliance of the bend points without creating a weakened hinge point, thus ensuring that there is no discontinuity in the circumferential seal against the vessel wall.
