Abstract: Methods and apparatus for supporting microneedles are provided. The apparatus includes a plurality of pedestals extending away from a base and transversely spaced- apart from each other by inter-pedestal volumes. Each of the pedestals has a transversely extending contact surface. For each of the pedestals, one or more microneedles extend from the contact surface of the pedestal.

Abstract: An apparatus for inserting a microneedle into tissue. The apparatus comprises microneedle supported by a backing to move therewith and a forcer that is selectably operable between a retracted state and an extended state. Upon operation of the forcer from the retracted state to the extended state, the forcer applies force to the backing which causes the backing to travel in an insertion direction toward the tissue. A releasable locking mechanism which, in a locking state, permits one-way motion of the backing in the insertion direction toward the tissue and lockingly engages the backing to prevent motion of the backing in a reverse direction opposed to the insertion direction, the releasable locking mechanism releasable, to a released state, which permits motion of the backing in the reverse direction. The forcer is disengaged from the backing when the locking mechanism lockingly engages the backing.
