摘要：
A distal protection device comprising a catheter having a first strut movable from a collapsed configuration to an expanded configuration having a first dimension and a second strut movable from a collapsed configuration to an expanded configuration having a second dimension larger than the first dimension. Movement of the first strut deploys filter material to a first position having a first deployed dimension and movement of the second strut to a first position deploys filter material to a second deployed dimension larger than the first expanded dimension.
