Abstract

Apparatus (20) and methods are provided for use in filtering emboli from a vessel and/or performing thrombectomy and embolectomy, wherein a vascular device comprises one or more support hoops (24) connected near a distal end (23) of a guide wire, each support hoop (24) having an articulation region, and a blood permeable sac (28) affixed to the support hoop (24) or hoops to form a mouth of the blood permeable sac (28). The mouth of the sac (28) closes when the apparatus (20) is collapsed for removal to prevent material from escaping from the sac (28).
