1. A device for administering a substance to a mammal, said device comprising:
- a top wall;
a bottom wall spaced apart from said top wall and having a substantially planar outer surface;
a plurality of projecting structures extending outwardly from said substantially planar surface from about 10 microns to about 1.5 mm;
side walls joining said top wall and said bottom wall, said top wall, bottom wall and side walls defining a reservoir for said substance to be delivered;
a device manipulating member which is deformable attached to at least one wall selected from said side walls, said top wall and combinations thereof and extending outward therefrom, said manipulating member having a dimension sufficient to grip and control said device; and
at least one passageway in fluid communication with said reservoir, wherein said at least one wall is deformable.

Abstract
The present invention relates to an apparatus and method for intradermally administering a pharmaceutical composition or other substance into and through the skin of a mammalian body in a manner that avoids or eliminates excess pain and discomfort normally caused as a result of the microabraders or microneedles entering the epithelial layers beneath the stratum corneum. In a preferred embodiment, the apparatus is a microdevice with an array of microabraders or microneedles with a manipulating member.

17. A device for administering a substance to a mammal, said device comprising:
-
a top wall; a bottom wall spaced apart from said top wall and having a substantially planar outer surface; a plurality of projecting structures extending a pre-selected distance outwardly from said substantially planar surface from about 10 microns to about 1.5 mm; side walls joining said top wall and said bottom wall, said top wall, bottom wall and side walls defining a fluid conduit, said fluid conduit in fluid communication with said projecting structures; a device manipulating member attached to said top wall and extending outwardly therefrom, said manipulating member having a dimension sufficient to grip and control said device;
said manipulating member having a deformable portion;
said manipulating member housing a reservoir and at least one passageway in selectable fluid communication with said fluid conduit, wherein selective fluid communication said reservoirs and said fluid conduit allows said substance to communicate with said projecting structures via said fluid conduit. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
