    摘要： Apparatus and methods are provided for use in filtering emboli from a vessel such as the ascending aorta, wherein a vascular device comprises a support hoop having an articulation region connected near a distal end of an elongated member, a blood permeable sac affixed to the support hoop so that the support hoop forms a mouth of the blood permeable sac, a guide wire, and a delivery sheath. 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.

    摘要： Apparatus and methods are provided for use in removing thrombus from a vessel, wherein a vascular device comprises an thrombectomy element for excising or ablating thrombus and a vascular filter for capturing emboli generated during removal of the thrombus. The vascular filter 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 so that the support hoop forms a mouth of the blood permeable sac. In a preferred embodiment, the thrombectomy element comprises a second support hoop and blood permeable sac attached to the guide wire proximal of the vascular filter support hoop.
