Abstract
A braided stent having an integral retrieval and/or repositioning loop includes a plurality of wires having first and second ends interbraided in a braided pattern to form a tubular stent having opposed atraumatic first and second open ends with each open end having a circumference. The first and second wires ends are disposed at the second stent open end and the wires are looped at the second stent open end so that none of the first or second wires ends are exposed at the circumference of second stent open end. The at least of two of said wires are formed into a repositioning and/or retrieval loop having an elongated portion circumferentially disposed at the first opposed open end. The reposition and/or retrieval loop also includes two sections which run adjacent to each other prior to crossing to permit grabbing of both sections simultaneously by a practitioner.
