Rotational thrombectomy wire with blocking device
First Claim
1. A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel, the apparatus comprising a thrombectomy wire having a first configuration and a second deployed configuration when exposed from a sheath, the wire having a straighter configuration in the first configuration, the wire being operatively connected to a motor for rotation of the wire to contact and break up the thrombus or other obstructive material, and a blocking device at a distal portion of the apparatus and connected to the thrombectomy wire such that the blocking device is advanced together with the thrombectomy wire into the lumen of the graft or vessel, the blocking device movable between a collapsed configuration and an expanded configuration, the blocking device in the expanded configuration configured to block thrombus dislodged by rotation of the wire.

Abstract
A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel. The apparatus includes a wire having a first configuration and a second deployed configuration, the wire having a straighter configuration in the first configuration. The wire is operatively connected to a motor for rotation of the wire to contact and break up the thrombus or other obstructive material. A blocking device at a distal portion of the apparatus is movable between a collapsed configuration and an expanded configuration, and is configured in the expanded configuration to block thrombus dislodged by rotation of the wire.

- 17. A thrombectomy apparatus for breaking up thrombus comprising a rotatable thrombectomy wire, the wire having a non-linear configuration, a blocking device connected to a distal portion of the wire distally of the non-linear portion of the wire, the blocking device advanceable together with the thrombectomy wire and expanding radially with respect to the wire, and a motor for rotating the wire to break up thrombotic material as the wire rotates about its axis.

20. A method for breaking up thrombotic material from a lumen of a vascular graft or vessel comprising;
-
inserting a sheath; inserting a thrombectomy apparatus having a rotatable thrombectomy wire and a blocking device connected to the thrombectomy wire; exposing the rotatable thrombectomy wire of the thrombectomy apparatus from the sheath to enable the blocking device to move from a collapsed position to an expanded position; rotating the wire to break up thrombotic material; and blocking at least some of the thrombotic material with the blocking device positioned at a distal portion of the thrombectomy wire; and withdrawing the thrombectomy wire to withdraw the blocking device. - View Dependent Claims (21, 22)
