Abstract
A micro-needle roller (MNR) infusion system for transdermal delivery of active agents, skin-care products, and other topical formulations is described herein. The infusion system of the instant invention comprises a needle roller assembly with needles enclosed in a housing with a vacuum line and a disposable cartridge having the active agent, the skin-care product or the topical formulation. The vacuum delivers the fluid and ensures that the skin is being pulled against the needle wheel surface to ensure that penetration of the needles is complete into the skin, simultaneously the fluid is flowing to the wheel and to skin as it rolls along with the outer housing of the tip cap assembly being occluded to the skin surface.
