Abstract
A device (3) comprising a sheet member (6) having a plurality of microprotrusions (4) for penetrating the skin and a rigid support (15) contacting and extending across the sheet member (6) for transmitting an applied force evenly across the length and width of the sheet member (6) to reproducibly and reliably penetrate the skin with the microprotrusions (4).
Claims37
A device for use in introducing or withdrawing an agent through a body surface, comprising:
- a thin, flexible sheet-like member having a plurality of microprotrusions extending from a body surface proximal portion of the member;
- and
- a structural support which defines one or more voids for an agent-containing or agent receiving reservoir and which extends substantially across, and makes contact substantially across, a width, length and/or diameter of the member, the support having greater rigidity than the member and wherein the structural support substantially reduces the tendency of the member to deflect upon application of a force to the top of the structural support.
