Claim:
1. An apparatus for delivering a substance to skin tissue, the apparatus comprising: an outer contact surface; at least one opening provided in the outer contact surface; a delivery arrangement adapted and configured to deliver the substance under elevated pressure through the at least one opening onto or into the skin tissue; and at least one vacuum channel provided in the outer contact surface surrounding at least a portion of the at least one opening, the at least one opening separated from the at least one vacuum channel by a portion of the outer contact surface; wherein the at least one vacuum channel is configured to apply a reduced pressure sufficient to maintain contact between the outer contact surface and the skin tissue to position the at least one opening against the surface of the skin tissue when the reduced pressure sufficient to maintain contact between the outer contact surface of the housing and the skin tissue is provided in the at least one vacuum channel; and wherein the at least one opening and the at least one vacuum channel are in coplanar alignment along the outer contact surface of the housing such that a portion of the outer contact surface of the housing separates the at least one opening from the at least one low-pressure channel.
