Microneedle array applicator device and method of array application
First Claim
1. An application device for applying a microneedle array comprising:
- a housing having a skin-contacting face defining an opening that can be positioned at a target site;
a first retainer disposed along and spaced from the skin-contacting face of the housing and adjacent to the opening, wherein the first retainer comprises a non-stick surface;
an impactor for accelerating the microneedle array from a first position, in which the microneedle array does not contact skin, to a second position at the target site, in which the microneedle array contacts skin; and
a drive member for biasing the impactor toward the second position;
wherein the impactor is configured to move along a substantially arcuate path from the first position to the second position.

Abstract
An applicator device including a housing, an impactor for impacting a microneedle array and accelerating the microneedle array toward the target site, wherein the impactor is capable of moving along an arcuate path to move the microneedle array toward the target site. Also, an applicator device including a housing, a patch applicator pivotally supported by the housing, and a torsion spring. The patch applicator has a retaining portion and a patch contacting portion, and the patch contacting portion is capable of moving along a substantially arcuate path between a first position and a second position. The torsion spring is capable of biasing the patch applicator relative to the housing.
