Abstract

A micro-needle device for delivering a dental local anesthetic that includes a micro-needle array and a hollow spheroid shaped container. The micro-needle array has a base and two or more elongate micro-needles. The elongate micro-needles have an interior surface defining an opening through the elongate micro-needle and the base has a first major surface and a second major surface through which the opening of the elongate micro-needle passes to provide a passage across the base. The hollow spheroid shaped container includes an inside surface, where the first major surface of the base and the inside surface of the hollow spheroid shaped container define a volume that is in fluid connection with each opening of the two or more of the elongate micro-needle. This allows the dental local anesthetic to flow from the volume of the micro-needle device through the opening of the two or more of the elongate micro-needle.
