Method and apparatus for enhancement of transdermal transport
First Claim
1. A method for enhancing transdermal transport, comprising(a) increasing the permeability of an area of skin with a skin permeabilizing device, wherein the device comprises a permeability monitoring circuit for monitoring at least one electrical parameter of the area of skin indicative of skin permeability, and wherein the device permeabilizes the skin using mechanical force;
- (b) monitoring the at least one electrical parameter of the area of skin using the permeability monitoring circuit;
(c) controlling the mechanical force applied to the area of skin by the device based on the at least on electrical parameter; and
(d) transporting a substance into and through the area of skin via passive diffusion.

Abstract
According to the present invention, a method for enhancing transdermal transport is disclosed. The method includes the steps of increasing a permeability an area of a membrane with a permeabilizing device. The membrane may be, inter alia, biologic skin or synthetic skin. The permeabilizing device may be an ultrasound-producing device. A substance is transported into and through the area the membrane. The substance may be a drug, a vaccine, or a component of interstitial fluid.
