ABSTRACT:
A method and apparatus for introducing a fluid agent into body tissue by causing transport of the fluid agent into the dermis of the subject. The outer surface of the skin of the subject is drawn against a plurality of micropenetrators such that microfissures are cloven into the epidermis and fluid may be introduced for diffusion or suction within the dermis. Suction creates a pressure gradient within the dermis to cause fluid take-up by the dermal tissue. The micropenetrators are produced by punching an array of protrusions in the surface of a thin sheet creating sharp edges for penetrating the epidermis.
