Abstract

Distal protection filter and method of using the same. A distal protection filter may be coupled to an elongate shaft. The filter includes a filter material coupled to a filter frame. The shape of the filter may be generally cylindrical or disc shaped. The filter material may capture embolic debris generated during an intravascular intervention.
