Abstract
Apparatus 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 connected near a distal end of a guide wire, each support hoop having an articulation region, and a blood permeable sac affixed to the support hoop or hoops to form a mouth of the blood permeable sac. The mouth of the sac closes when the apparatus is collapsed for removal to prevent material from escaping from the sac.
