First Claim
Patent Images
1. An integrated system for delivering a microneedle array, the system comprising:
- a housing having a height of at least 2 mm and no greater than 3.0 cm, a cavity therein, and including an applicator device;
a carrier assembly including a solid microneedle array, wherein a portion of the carrier assembly is attached to the housing proximate the cavity and is in contact with a portion of the applicator; and
wherein neither the carrier assembly nor the array are attached to the applicator device;
a stored energy device comprising one or more bifurcating-springs that are capable of undergoing a shape change as a result of a predetermined force normal to a major plane of the stored energy device, wherein at least a portion of the stored energy device is located within the housing; and
wherein the stored energy device can be actuated to apply force on the carrier assembly;
wherein the applicator device further comprises an actuator; and
wherein the actuator is movable within the housing in a certain direction orthogonal to the major plane of the stored energy device and the actuator comprises a screw received in a series of helical threads in the housing.

Abstract
The present disclosure provides a low-profile system and methods for delivering a microneedle array. The delivery system includes a housing that may be secured to and temporarily worn on a patient'"'"'s skin. A carrier assembly coupled to a microneedle array is received in the housing proximate an applicator device. The carrier assembly is at least releasably secured to the housing and it is typically not attached or otherwise fixed to any portion of the applicator device.
