Abstract: A transdermal drug delivery apparatus includes a housing for being fastened to a user, a microneedle assembly for being engaged against the skin of the user, a first force provider for providing a first force for forcing the microneedle assembly outwardly from the housing and against the skin, a reservoir movably carried by the housing for containing the fluid and for being in fluid communication with the microneedle assembly, and a second force provider for providing a second force for causing at least some of the fluid to flow from the reservoir to the microneedle assembly after the reservoir has moved into fluid communication with the microneedle assembly.

Abstract: A controller assembly of a fluid delivery apparatus includes a body component and a plunger component slidably coupled to the body component. The plunger is positionable between a first position in which the plunger is nearest to the body component, and a second position in which the plunger component is furthest from the body component. A bias assembly positioned between the body component and the plunger component applies a two stage force profile to the plunger component. The bias assembly includes a first and a second biasing member. In the first position, the first and second biasing members apply first and second forces profiles, respectively, to the plunger component. In the second position, the first biasing member is prevented from applying the first force profile to the plunger component, and the second biasing member applies the second force profile to the plunger component.

Abstract: A transdermal drug delivery apparatus includes a receptacle having a housing and a microneedle assembly mounted to the housing. The apparatus includes a reservoir for being mounted to the receptacle. The reservoir has an interior for containing fluid for being supplied to the microneedle assembly. The apparatus is adapted so that, when the apparatus is assembled, the reservoir is configured to move relative to the microneedle assembly along a path from an outer position to an inner position. The reservoir is closer to the microneedle assembly in the inner position than in the outer position. In the outer position, the reservoir is out of fluid communication with the microneedle assembly, and in the inner position, the reservoir is in fluid communication with the microneedle assembly. The apparatus also includes a plurality of connector parts spaced apart from one another along the path.

Abstract: A uniformity control membrane can be securely engaged against an upstream side of a microneedle array and configured so that resistance to flow through the uniformity control membrane is substantially greater than the resistance to flow through the microneedle array. These differences in flow resistance can facilitate uniform administration of a liquid formulation into the patient's skin across a broad area and at a relatively low pressure, such as by way of capillary action. The administration of the liquid formulation into the patient's skin across the broad area can result from the liquid formulation being administered by way of at least a majority of the microneedles of the microneedle array.

In addition, the gas extraction device includes an impermeable membrane coupled to the second layer opposite the vent membrane. The first channel is configured to receive a fluid having a gas dispersed therein. The fluid is pressurized to move the fluid through the first channel against the vent membrane and to move the gas through the vent membrane.
