A cannula having a notch feature and a cannula feature that at least partially overlap each other is described herein. Generally, the cannula comprises a tubular shaft with a substantially constant outer diameter. The cannula feature comprises at least one surface that extends laterally past the cannulas outer diameter. For instance, the cannula feature may comprise a crimp feature or a welded ferrule feature. The cannula feature further comprises a distal end and a proximal end. Accordingly, a portion, if not all, of the notch feature is disposed between the cannula features distal end and proximal end. The cannula may be used in any suitable assembly, including a catheter assembly comprising a needle capture mechanism. FIG. 1
