Abstract
An embolic protection device includes a guide member having a distal end, a proximal end, and a lumen extending from the distal end to the proximal end. Additionally, the embolic protection device includes a filter assembly having a plurality of struts extending from the distal end of the guide member. The filter assembly further includes a filter media adapted to filter material from a blood stream coupled to at least two of the plurality of struts. The filter media can have an open proximal end and a closed distal end. The device can also include a sleeve at least partially surrounding the plurality of struts and the filter media for restraining the filter device in a collapsed position during an insertion procedure. The embolic protection device can also include additional loops of material surrounding the struts and a tether wire securing the sleeve and loops in the collapsed position.
