Abstract

An applicator and method for applying a microneedle device to skin. The applicator can include a housing and a reciprocating support structure slidably engaged with the housing. The reciprocating support structure can have a plurality of alignment feet. The applicator can have a lockout mechanism that prevents actuation if the alignment feet are not evenly aligned. The applicator can include a device life indicator that is capable of counting the number of use cycles that the applicator has undergone and providing feedback to the user. The applicator can include a dose timer capable of determining the time that has elapsed after actuation of the device and providing feedback to the user.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 61 / ,750,128, filed January 8, 2013, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure generally relates to applicators and methods for applying microneedle devices to skin to treat areas of skin and / or to deliver active agents to skin. Background technique [0004] Transdermal and topical drug delivery are useful for therapeutic treatment, but the number of molecules that can be effectively delivered using these routes is limited by the barrier properties of the skin. The main barrier to transporting molecules through the skin is the stratum corneum (the outermost layer of the skin). [0005] Various skin treatments have been proposed in order to increase the permeability or porosity of the outermost layers of the skin, such as the stratum corneum, thereby enhancing the abil...
