Integrated vascular device having thrombectomy element and vascular filter and methods of use
First Claim
1. Apparatus suitable for performing thrombectomy comprising:
- an elongated member having a distal region;
a support hoop attached to the distal region, the support hoop having a reduced-thickness articulation region, the hoop attached to the elongated member;
a blood permeable sac affixed to the support hoop so that the hoop forms a mouth of the blood permeable sac;
a thrombus removal element disposed proximal of the support hoop, the thrombus removal element movable in a proximal direction independent of the elongated member.

Abstract
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.

18. A method of trapping thrombus and/or emboli during a medical procedure, the method comprising:
-
providing apparatus comprising an elongated member having a distal region, a support hoop having an articulation region coupled to the distal region of the elongated member, a blood permeable sac affixed to the support hoop so that the hoop forms a mouth of the blood permeable sac, and a thrombus removal element disposed proximal to the support hoop;
positioning the apparatus in a contracted delivery state within a delivery sheath;
advancing the delivery sheath to a desired location within a patient'"'"'s vessel; and
withdrawing the delivery sheath to expand the apparatus to a deployed state wherein the support hoop seals against the vessel wall, and the thrombus removal element is configured to excise or ablate the thrombus. - View Dependent Claims (19, 20, 21, 22)
