Abstract: An endovascular apparatus takes the form of an expandable tubular body having a retriever, which may include a pair of interconnected hooks. The retriever may be formed from a single piece of material forming the tubular body, and in the case of a pair of hooks thus has a thickness corresponding to approximately twice the wall thickness of the tubular body. The innermost radial portion of the hooks may be offset from a central axis of a lumen formed by the tubular body, which facilitates free insertion of a balloon or the like for purposes of expanding the tubular body. Related methods of manufacturing an endovascular apparatus with a retriever are also described herein.

Abstract: An apparatus for performing an endovascular procedure using ultrasonic energy includes a catheter comprising a wave guide including an expandable portion for delivering the ultrasonic energy from a source for performing the endovascular procedure. The expandable portion may comprise a plurality of wires formed of a shape memory material. A retractable sheath may be provided for receiving the plurality of wires in the non-deployed position and for being withdrawn to expose the wires in the deployed position. A linear actuator for moving the plurality of wires in a longitudinal direction or a rotary actuator for rotating the plurality of wires may also be provided.
