Rotational thrombectomy wire with blocking device
First Claim
1. An apparatus for insertion into a lumen of a vascular graft or vessel, the apparatus comprising wire, a motor operatively connected to the wire and actuable for rotation of the wire to dislodge particles, and a blocking device at a distal portion of the apparatus, the blocking device expandable from a reduced profile insertion position to an expanded position within the lumen to block dislodged particles from distal flow distal of the apparatus, wherein the wire is sinuous in configuration and assumes its sinuous configuration when in a deployed configuration and is insertable in a collapsed configuration.

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.
