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;
an impactor for impacting the microneedle array and accelerating the microneedle array toward the target site,wherein the impactor is capable of moving along a substantially arcuate path to move the microneedle array along an arcuate path toward the opening of the skin-contacting face of the housing; and
a drive member for biasing the impactor relative to the housing, wherein the drive member has a length extending from a fixed end attached to the housing to a movable end, wherein the drive member is bendable deflectable, relative to the housing, along the length of the drive member, wherein the movable end of the drive member is configured so as to be able to contact and propel the microneedle array and wherein the microneedle array is affixed to the movable end of the drive member.

Abstract
An applicator device (20) including a housing (22), an impactor (62) 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 (40) and a patch contacting portion (70), 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.
