Distal protection device
First Claim
1. A distal protection device comprising a catheter having a first strut movable from a collapsed configuration to an expanded configuration and a second strut axially spaced from the first strut and movable from a collapsed configuration to an expanded configuration, the first strut having a first dimension and the second strut having a second dimension larger than the first dimension, the first and second struts being separately deployable, wherein movement of the first strut deploys filtering material to a first position having a first deployed dimension and movement of the second strut deploys filtering material to a second deployed dimension larger than the first deployed dimension.

Abstract
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.

- 1. A distal protection device comprising a catheter having a first strut movable from a collapsed configuration to an expanded configuration and a second strut axially spaced from the first strut and movable from a collapsed configuration to an expanded configuration, the first strut having a first dimension and the second strut having a second dimension larger than the first dimension, the first and second struts being separately deployable, wherein movement of the first strut deploys filtering material to a first position having a first deployed dimension and movement of the second strut deploys filtering material to a second deployed dimension larger than the first deployed dimension.
- 11. A distal protection device comprising a tube having a plurality of cutouts forming at least one distal elongated strut and at least one proximal elongated strut, the struts movable from a retracted to an expanded position, filter material overlying at least a portion of the struts, and an actuating member operatively connected to a portion of the tube wherein movement of the actuating member moves the portion of the tube to thereby move the at least one distal elongated strut and the at least one proximal elongated strut to the expanded position.
- 21. A distal protection device comprising a catheter having a tube formed with cutouts therein to form a first set of elongated struts and a second set of elongated struts, each of the elongated struts having a proximal end and a distal end, the elongated struts being movable between a retracted position and an expanded position wherein the distance between the proximal end and distal end in the retracted position is a first distance and the distance between the proximal end and distal end in the expanded position is a second distance less than the first distance, in the expanded position the elongated struts forming loops with an opening lying in a plane substantially parallel to a transverse axis of the tube, and filter material deployable by the loops of the struts, the first set of struts and the second set of struts being separately movable to the expanded position to enable actuation of the first set of struts to accommodate a first size vessel and actuation of the second set of struts to accommodate a second different size vessel.
