Abstract:
1. A method of filtering and capturing particles in the vasculature, comprising the steps of: providing delivery device with a filter device positioned therein, the filter device comprising a frame and first and second filter portions secured to the frame, wherein the frame has a folded configuration whereby the first and second filter portions are folded by pivoting about an axis positioned between portions of the first and second filter portions closest to each other and a deployed configuration; advancing the delivery device through a first vessel; deploying the filter device from the delivery device; with the delivery device positioned in the first vessel, positioning the first filter portion relative to the first vessel such that particles traveling into the first vessel will be trapped in the first filter portion and that an open portion of the first filter portion faces forward away from the delivery device; with the delivery device positioned in the first vessel, positioning the second filter portion relative to a second vessel such that particles traveling into the second vessel will be trapped in the second filter portion and that an open portion of the second filter portion faces forward away from the delivery device; and pivoting the first and second filter portions toward one another about the axis to bring the open portions of the first and second filter portions towards each other to capture the particles trapped in the first and second filter portions.
