Improved microprotrusion abrasion devices having fluid retaining or directing patterns, and specific design parameters and method for delivery of substances into the skin. Various configurations of such devices are disclosed, including domed, channeled, patterned and stepped.

Microprotrusion arrays and methods for using same to deliver substances into tissue

A method and device for the delivery of a substance into skin via the rotational movement of a microabrader device reduces the effects of operator variability. The method includes applying a substance to an area of a patient's skin through the rotational movement of microprotrusions which may be imparted by a spring device present in the microabrader device or the motion of the operator through the handle of the microabrader device. The device may further include system and methods for monitoring pressure of the device against the skin and thereby promote consistency between applications and control of penetration depth. The delivered substance may be placed on the microprotrusions and a reconstituting liquid included in the microabrader device.
