ABSTRACT:
Device for treating pathological conditions of skin surfaces, which comprises a main component that includes a body and a contact layer superimposed to one another, wherein the body is porous to provide storage capacity for liquid medicament fed to it and permeable for transmitting the medicament to the contact layer by compression or capillarity or both. The contact layer is also porous for transmitting the medicament received from the body to the skin surface being treated and has a mildly or strongly abrasive outer surface for removing damaged surface skin tissue. The device also comprises a delivery apparatus for feeding liquid medicament to the body of the main component and, an optional storage container for the liquid medicament.
