A stent has a braided wire body formed from at least a first wire and a second wire. The first wire has a first cross-sectional area and the second wire has a second cross-sectional area different from the first cross-sectional area. The proximal end of the braided wire body has a plurality of peaks, the peaks including first peaks and first loop ends. The first loop ends alternate circumferentially with the first peaks and the first loop ends extend proximally beyond the first peaks.
