Integrated stent repositioning and retrieval loop

摘要

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.

主权项

1. A stent comprising:
a stent body, the stent body having first and second open ends and a length therebetween, and being formed from a plurality of wires, wherein two of the plurality of wires forming the stent body extend the length of the stent body, the first open end having a first circumference and the second open end having a second circumference, wherein said two of said plurality of wires forming said stent body are further formed into a repositioning and/or retrieval loop having an elongated portion circumferentially disposed at said first open end, and wherein said elongated circumferential portion of said repositioning and/or retrieval loop comprises:
a first wire loop completely traversing said first circumference at said first opposed open end, said first wire loop being formed from a first wire of said two wires, wherein the first wire loop extends longitudinally away from the first open end, anda second wire loop partially traversing said first circumference formed from a second wire of said two wires, wherein the second wire loop has an inverted U-shape, and wherein the second wire loop extends longitudinally away from the first open end,wherein a circumferential portion of said second wire loop is juxtaposingly disposed to a circumferential portion of said first wire loop.
