The hypodermic needle is described as having a proximal end, a distal end having a tissue-piercing tip, and a lumen extending from the proximal end to the distal end. The elongate body may have a channel formed in its outer surface. The channel may be concave or formed in the outer wall. The portion having the channel may maintain a circular lumen, or the lumen may be non-circular or conform to the shape of the channel. Additionally, the elongate body may have a flattened portion along its length. The flattened portion may be at the distal-most portion of the elongate body extending proximally from the distal tip. The elongate body may also include a notch formed in the outer wall to communicate with the lumen or open to the lumen. The opening of the notch may traverse the lumen or be aligned with the lumen.
