Abstract
Embodiments of the invention include methods of tissue/wound treatment and associated devices and systems, including devices for breaching bio-films contained in and around wounds, devices for maximizing moisture vapor transmission rate, and tissue dressings with added barrier features for permeable surfaces.
Claims13
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.

A method for treating tissue comprising the steps of:
- (a) providing a tissue dressing comprising a reservoir having contained therein one or more therapeutic materials with a permeable film closing one side of the reservoir, and an array of a plurality of micropenetrators provided as abrasive particles adjacent to the permeable film, the micropenetrator particles not piercing the permeable film;
- (b) affixing the tissue dressing to a tissue area;
- and
- (c) applying pressure, causing the micropenetrator particles to penetrate and disrupt a surface of the tissue area, delivering therapeutic material from the reservoir into the tissue.
