1. An arrangement comprising:
- a needle comprising a first end and a second end opposite the first end, and a lumen having an inner diameter and a longitudinal length; and
at least one fluid transport enhancing projection comprising an outer peripheral surface and extending toward the first end;
wherein the at least one projection extends from the base and is constructed and arranged to enhance fluid transport by enhancing capillary forces drawing fluid along the outer peripheral surface of the at least one projection.
