A knitted stent extending along a central longitudinal axis may comprise a filament forming a plurality of cells arranged in a plurality of columns and a plurality of rows. The plurality of rows may extend parallel to the central longitudinal axis. The plurality of columns may extend circumferentially around the central longitudinal axis. The plurality of rows may include a plurality of loop rows and a plurality of rung rows interposed between adjacent loop rows. Each cell within the plurality of loop rows may include a circumferential loop element connected to two longitudinally oriented connector elements. The plurality of rung rows may include a plurality of circumferential rung elements connected to adjacent loop rows. A majority of the plurality of loop rows may include open cells having an open end. At least one of the plurality of loop rows may include a plurality of closed cells having a closed end.
