Abstract
An apparatus includes a housing, an adjustment member, and a microneedle. The housing can be coupled to a medicament container, and includes a hub surface that can contact a target surface. The adjustment member is within the housing and separates an inner volume of the housing into a first chamber and a second chamber. The first chamber is fluidically coupled with the medicament container. The adjustment member, which is coupled to the microneedle, can transition between a first configuration and a second configuration. A proximal end portion of the microneedle is fluidically coupled to the first chamber such that a substance can be conveyed from the medicament container through the microneedle. A distal tip of the microneedle extends from the hub surface by a first distance when the adjustment member is in the first configuration, and by a second distance when the adjustment member is in the second configuration.
