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 rotatable thrombectomy wire, 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, the blocking device configured to block thrombus dislodged by rotation of the wire, wherein the wire spins independent of the blocking device such that the blocking device remains substantially stationary as the wire rotates to break up thrombus or other obstructive material.

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.
