    Abstract: A microneedle injection and infusion apparatus, and a method of using same. The apparatus (100) can include a housing (102), a microneedle array holder (106) for holding a microneedle array (107), and a shuttle (125) that holds a cartridge (e.g., that contains an active agent). The microneedle array holder can be movable between a retracted position and an extended position. The shuttle can be movable between a first position in which the cartridge is not in fluid communication with a fluid path and a second position in which the cartridge is in fluid communication with the fluid path. The apparatus can further include an actuator (104) movable between a first position and a second position. The method can include moving the actuator to its second position to allow the shuttle to move toward its second position, wherein movement of the shuttle toward its second position allows the microneedle array holder to move to its extended position.

    Abstract: A microneedle injection apparatus comprising a dual cover. The apparatus can include a housing having a base and a cavity; a microneedle array comprising a first side comprising a plurality of microneedles; and a microneedle array holder configured to hold a microneedle array and located in the housing. The microneedle array holder can be movable between a retracted position, and an extended position. The apparatus can further include a cover configured to be positioned to cover the opening in the base of the housing. The cover can include (i) a first portion configured to cover at least a portion of the base of the housing adjacent the opening, and (ii) a second portion configured to be received in the cavity of the housing and further configured to cover the plurality of microneedles on the microneedle array when the microneedle array holder is in the retracted position.

    Abstract: A microneedle injection apparatus comprising an inverted actuator. The apparatus can include a housing having a base and a cavity, and a microneedle array holder configured to hold a microneedle array within the cavity of the housing. The microneedle array holder can be movable between a retracted position, and an extended position. The apparatus can further include an actuator movable with respect to the housing and the microneedle array holder between a first position and a second position to cause the microneedle array holder to move from the retracted position to the extended position. At least a portion of the actuator can be located on a skin-facing side of the apparatus (e.g., adjacent the base of the housing) and can be configured to be moved from the first position to the second position in response to the apparatus being pressed toward the skin surface.
