Patent ID: 8882797

Claim:
A method of providing embolic protection during treatment of a vessel, the method comprising: advancing a microcatheter in the vessel, wherein advancing the microcatheter includes crossing a thrombus with a distal end of the microcatheter; inserting a textile structure in a collapsed state into the microcatheter, the textile structure comprising a plurality of self-expanding bulbs and a plurality of necks, wherein the plurality of self-expanding bulbs comprises five to twenty self-expanding bulbs, each of the plurality of self expanding bulbs having a spherical shape or an oblong shape, wherein pairs of the self-expanding bulbs are spaced by a neck of the plurality of necks; advancing the textile structure through the microcatheter proximate to the distal end of the microcatheter, wherein advancing the textile structure includes crossing the thrombus with a distal-most bulb of the plurality of self-expanding bulbs; after advancing the textile structure, retracting the microcatheter to unsheathe a length of the textile structure, wherein retracting the microcatheter to unsheathe the length of the textile structure comprises: unsheathing at least the distal-most bulb of the plurality of self-expanding bulbs from the microcatheter, and self-expanding at least the distal-most bulb of the plurality of self-expanding bulbs from the collapsed state to an expanded state; and removing the thrombus from the vessel, wherein, in the expanded state, the distal-most bulb: apposes sidewalls of the vessel, and filters emboli released during the removing the thrombus from the vessel.
