1. A tissue dressing treatment device comprising;
a reservoir having contained therein one or more therapeutic materials, the reservoir closed on one side by a permeable film; and
an array of a plurality of micropenetrators provided as a plurality of sharp, penetrating and abrasive particles adjacent to the permeable film, the micropenetrator particles not piercing the permeable film;
wherein, with the tissue dressing applied to a tissue area, applying pressure causes the micropenetrator particles to penetrate and mechanically disrupt a surface of the tissue area, enabling delivery of the therapeutic material from the reservoir to the tissue.
