INTEGRATED MICRONEEDLE ARRAY DELIVERY SYSTEM

摘要

The present disclosure provides low-profile systems and methods for delivering a microneedle array. A 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 a stored energy device. The stored energy device can be designed to store a predetermined amount of potential energy that is greater or substantially greater than the energy necessary to release said energy. As the stored energy device is potentially capable of releasing substantially more energy than is required to cause the release, the amount of normal force applied to the skin can be minimized while sufficient application velocity is still generated.

主权项

1. A system for delivering a microneedle array, the system comprising:
a housing having a cavity therein and an attachment surface at least partially surrounding the cavity; a carrier assembly including a solid microneedle array received in the cavity; a stored energy device coupled to a portion of the interior of housing and in contact with a portion of the carrier assembly; and an actuator operable to supply an activation energy to the stored energy device in a direction orthogonal to the major plane of the array, wherein the stored energy device is capable of transferring an application energy orthogonal to the major plane of the array that is greater than the activation energy.
