1. A distal protection device for capturing emboli during an endovascular procedure at a treatment area, said device comprising:
- a delivery member having a proximal end and a distal end;
a self-expanding filter assembly adjacent said distal end of said delivery member, said filter assembly having a proximal portion and a distal portion, and having a proximal end longitudinally fixed to said delivery member and a distal end longitudinally fixed to said delivery member; and
a sheath being moveable over at least part of the proximal portion of said filter assembly for positioning said filter assembly between a deployed position and a collapsed position.

Abstract
The present invention is a distal protection device for use with a delivery member. A filter assembly is located on the distal end of the delivery member. The filter is deployed distally of the region to be treated to capture emboli released during and immediately after the procedure. The filter is then retracted to retain any captured emboli and then removed from the patient.

14. A method of using a distal protection device in a vascular treatment region within a patient, said method comprising:
-
providing a delivery member and a moveable sheath covering a self-expanding filter assembly located adjacent a distal end of said delivery member, said delivery member being longitudinally fixed to said filter assembly at a proximal end and a distal end of said filter assembly;
positioning said filter assembly distal of said treatment region;
retracting said sheath proximally to deploy said filter assembly distal of the treatment region;
conducting a procedure at said treatment region;
capturing emboli in said filter assembly during said procedure;
moving said sheath distally over said filter assembly to at least partially collapse said filter around said captured emboli; and
removing said at least partially collapsed filter and captured emboli from said patient. - View Dependent Claims (15, 16, 17, 18, 19)
