Zusammenfassung:	Devices and methods for removing a thrombus (clot) from a vascular structure of a living subject. An embodiment of a thrombus removal device comprises first and second annular members, the first annular member being adapted to slide over a guidewire placed in a vascular structure, the second annular member being coupled to the first annular member and having a suction flow path therethrough, the first annular member having an expandable mesh structure disposed at a distal portion thereof, the mesh structure being deployable to an expanded configuration by movement of an actuating element extending along the second annular member. An embodiment of a thrombus removal method comprises advancing the device to position the mesh structure downstream of the thrombus by sliding the first annular member over the guidewire, applying a suction force to the suction flow path of the second annular member, deploying the mesh structure, and retracting the device to cause the mesh structure to engage the thrombus.
