Abstract
Apparatus and methods are provided for use in filtering emboli from a vessel and performing thrombectomy and embolectomy, wherein a vascular device comprises a support hoop having an articulation region connected near a distal end of a guide wire, and a blood permeable sac affixed to the support hoop, and a delivery sheath that permits the vascular device to be deployed in a “rapid exchange” mode. The 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.
