An improvement to a thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel having a wire and flexible sheath relatively movable, wherein the wire is sinuous in configuration and assumes its sinuous configuration when in the deployed configuration and has a straighter configuration in the first configuration. The wire is operatively connected to a motor for rotation of the wire to enable peaks of the sinuous wire to contact a wall of the lumen to break up the thrombus or other obstructive material. The improvement to the thrombectomy apparatus comprises the wire being formed of an inner core formed by a plurality of twisted wires and an outer wire wound directly around the inner core, wherein a distal portion of the outer wire extends distal of the inner core and progressively tapers towards a distal end to form a tapered region.

The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for a an intravascular stent having a plurality of cylindrical rings connected by undulating links. The plurality of cylindrical rings may assume an undulating shape that is similar to the shape of the undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen.

A system which is capable of accurately treating an affected area in a body lumen. The system includes a catheter which is positionable in the body lumen at the treatment site and includes an interventional device such as a self-expandable stent which may be deployed in the blood vessel at the treatment site. The system also includes an expansion retention member, adapted to be extended about the interventional device. The system further includes an extendable member, adapted to be extended about the expansion retention member and the interventional device, for delivery of the interventional device to the treatment site, and to be retractable from extending about the expansion retention member for enabling the interventional device to expand at the treatment site.
