Methods, systems, and devices for providing embolic protection and removing embolic material
First Claim
1. A filter device for percutaneous insertion into a blood vessel during a procedure, the 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) filtering means for filtering material from a blood stream, said means being coupled to said guide member and having a proximal end and a distal end;
(c) a first restraining means for restraining said filtering means, wherein said first restraining means comprises a sleeve at least partially surrounding said filtering means, wherein said sleeve is releasably secured with a tether wire, said tether wire passing through a plurality of openings in said sleeve, said tether wire being at least partially releasable by an operator to allow deployment of said filter; and
(d) a second restraining means for restraining said filtering means, said second restraining means cooperating with said first restraining means in restraining said filtering means in an undeployed position.

Abstract
An embolic protection device includes a guide member having a distal end, a proximal end, and a lumen extending from the distal end to the proximal end. Additionally, the embolic protection device includes a filter assembly having a plurality of struts extending from the distal end of the guide member. The filter assembly further includes a filter media adapted to filter material from a blood stream coupled to at least two of the plurality of struts. The filter media can have an open proximal end and a closed distal end. The device can also include a sleeve at least partially surrounding the plurality of struts and the filter media for restraining the filter device in a collapsed position during an insertion procedure. The embolic protection device can also include additional loops of material surrounding the struts and a tether wire securing the sleeve and loops in the collapsed position.
