Abstract
Apparatus and methods are provided for use in filtering emboli from a vessel and performing thrombectomy and embolectomy, wherein a vascular device comprises one or more support hoops, each having an articulation region connected near a distal end of a guide wire, and a blood permeable sac affixed to the one or more support hoops so that the support hoops form a mouth of the blood permeable sac. Each articulation region comprises a reduced thickness region of the support hoop that prevents kinks from forming in the support hoop when the apparatus is contracted to its delivery state, and curved regions that close the mouth of the sac to prevent material escaping from the sac when the apparatus is collapsed for removal.
