Abstract
An expandable filtering material expands within a body vessel (e.g. artery) when fluid flows through the vessel. Expandable pockets in the filtering material trap emboli released in the fluid. The filtering material is inserted into the vessel at a particular position distal to a lesion in the direction of the fluid flow. A protective sleeve covers the filtering material. An interventional device is disposed in the vessel at the lesion position to treat the lesion. The sleeve is removed from the expandable filtering material thereby expanding the filtering material within the vessel. The interventional device treats the lesion and opens up the vessel at the lesion position. The interventional device is thereafter removed. Retaining pockets in the expandable filtering material trap emboli released in the fluid of the body vessel.
