Abstract
An intradermal mini-needle interface has a penetration limiter providing a skin contact edge and a hollow hypodermic needle having a beveled penetrating portion protruding forward beyond the skin contact edge by no more than 3 mm. At least one skin contact surface defines a skin contact plane parallel to, or at a shallow angle to, the needle axis. The skin contact plane intersects the skin contact edge substantially at a base of the penetrating portion. Preferably, the penetration limiter is asymmetric under rotation about the needle axis.
