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 (100) comprising an inverted actuator. The apparatus can include a housing (102) having a base and a cavity, and a microneedle array holder (106) configured to hold a microneedle array (107) 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 (104) 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.
