Abstract
A stent includes a tubular body formed of one or more interwoven wires, the tubular body having first and second opposing open ends and a lumen extending therebetween. The stent further includes a first anchor member disposed adjacent the first open end and a second anchor member disposed adjacent the second open end, the first and second anchor members each extending radially outward from the tubular body, the first and second anchor members each having an outer diameter larger than an outer diameter of the tubular body disposed between the first and second anchor members. A plurality of spacer members are disposed around the first open end and extending longitudinally beyond the first open end, wherein when a pulling force is applied to the spacer members, the outer diameter of the tubular body is not reduced.
