1. A device for use in introducing or withdrawing an agent through a body surface, comprising:
- a sheet member having a plurality of microprotrusions extending from an edge of the sheet member and in a direction defined by a plane of the sheet member, for piercing the body surface, the sheet member having a configuration which defines a void, the sheet member when in use being oriented in an approximately perpendicular relation to the body surface with the edge having the microprotrusions being proximal the body surface;
an agent-containing or agent-receiving reservoir in the void, the reservoir when in use being in agent transmitting communication with the body surface andmeans for holding the sheet member on the body surface;
the means for holding being selected from the group consisting of anchoring barbs on the microprotusions, angled microprotrusions, curved microprotrusions, an adhesive, a tape, a strap and a bandage.

20. A device for use in introducing or withdrawing an agent through a body surface, comprising:
-
a sheet member having a plurality of microprotrusions for piercing the body surface, the microprotrusions extending from a body surface proximal edge of the sheet member and in a direction defined by a plane of the sheet member, the sheet member having a configuration which defines a void; an agent-containing or agent-receiving reservoir in the void, the reservoir when in use being in agent transmitting communication with the body surface; a support which contacts and extends across a second edge of the sheet member; and means for holding the sheet member on the body surface, the means for holding being selected from the group consisting of anchoring barbs on the microprotrusions, angled microprotrusions, curved microprotrusions, an adhesive, a ea strap and a bandage. - View Dependent Claims (21, 22, 23, 24, 25, 26)
