Patent ID: 6962598

Claim:
A filter device comprising: (a) a guide member comprising a distal end, a proximal end, and a lumen extending from the distal end to the proximal end; (b) a filter assembly coupled to said guide member, said filter assembly comprising: (i) a filter comprising a proximal end with an opening formed therein; and (ii) a plurality of struts coupled to said proximal end of said filter, each of said plurality of struts being biased to open said opening; and (c) an actuating assembly coupled to said guide member and said filter assembly, said actuating assembly comprising: (i) a restraining member cooperating with said plurality of struts, said restraining member applying a restraining force to the plurality of struts to prevent the plurality of struts from extending outwardly; (ii) an actuating member coupled to said restraining member and extending toward said proximal end of said guide member, said actuating member is at least partially disposed in said lumen of said guide member; and (d) an actuating element coupled to a proximal end of said actuating member, said actuating element being adapted to move in a proximal direction to release the restraining force to enable said plurality of struts to extend outwardly.
