1. A stent, the stent comprising:
an elongated tubular member comprising at least one filament interwoven to ferric define a plurality of cells, the elongated tubular member configured to move between a collapsed configuration and an expanded configuration; and
at least one barb fixed to the at least one filament that is interwoven to define the plurality of cells, the at least one barb having a first end, a second end, and a middle region extending therebetween, wherein both the first end and the second end are fixed to the at least one filament at spaced apart positions, and the middle region is free of attachment to the elongated tubular member in the expanded configuration;
wherein the middle region of the at least one barb is configured to be positioned radially inward of and under an adjacent winding of the at least one filament when the elongated tubular member is in the collapsed configuration and to extend radially away from the elongated tubular member when the elongated tubular member is in the expanded configuration.
