  • Patent number: 11219721
    Abstract: An attachment band for a fluid delivery apparatus includes an annular body having a wall defining a hollow inner space, an adjacent pair of attachment apertures extending through the wall, and an indicator aperture extending through the wall opposite the pair of attachment apertures. The indicator aperture includes an indicator portion that is configured to present an indication to a user of the fluid delivery apparatus of a tightness of the attachment band. A first strap extends radially outward from the annular body of the attachment band and is substantially aligned with the attachment apertures. A second strap extends radially outward from the annular body and is substantially aligned with the indicator aperture.

  • Patent number: 11213666
    Abstract: A method for administering a medicament to a patient includes placing a fluid delivery apparatus with the medicament in contact with a portion of the skin of said patient. A flow rate of the medicament from the fluid delivery apparatus is adjusted such that the medicament is delivered to the patient for a predetermined time period. The fluid delivery apparatus includes a controller assembly having a body component defining an axis 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 is positioned between the body component and the plunger component. The bias assembly is configured to apply a two stage force profile to the plunger component.

  • Patent number: 11179554
    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.

  • Publication number: 20210196567
    Abstract: A cartridge, which may be suitable for use as a portion of a transdermal drug delivery apparatus, may include a body at least partially defining an interior for containing fluid for being delivered by the transdermal drug delivery apparatus. The body may also at least partially define first and second openings to the interior of the body, wherein the first and second openings are respectively proximate opposite first and second ends of the body. The cartridge may also include a self-sealing member at least partially closing the first opening, and a movable member at least partially closing the second opening, wherein at least a portion of the movable member is for being urged into the interior of the body for increasing pressure within the interior of the body.

  • Patent number: 11040183
    Abstract: A receptacle, which may be suitable for use as a portion of a transdermal drug delivery apparatus, may include a housing for being fastened to the user, a force provider that is elastic, at least one deformable component, and a microneedle assembly movably mounted to the housing for moving inwardly and outwardly relative to the housing. The force provider may be positioned between the housing and the microneedle assembly for forcing the microneedle assembly outwardly relative to the housing and against the skin of the user. The at least one deformable component may be connected between the microneedle assembly and the housing for both allowing relative movement between the microneedle assembly and the housing, and at least partially restricting the microneedle assembly from falling away from the housing.

  • Publication number: 20210106752
    Abstract: A gas extraction device for a fluid delivery apparatus includes a first layer and a vent membrane coupled to the first layer. The vent membrane enables a gas to pass through the vent membrane and prevents a fluid from passing through the vent membrane. The gas extraction device also includes a second layer coupled to the vent membrane opposite the first layer. The second layer has a first channel formed therethrough. 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.

  • Patent number: 10328248
    Abstract: A controller, which may be used in a transdermal drug delivery apparatus, includes a housing, a pushing mechanism mounted for moving relative to the housing, a force provider positioned between the housing and the pushing mechanism for moving the pushing mechanism relative to the housing, and a latching mechanism for selectively restricting and allowing relative movement between the housing and the pushing mechanism. The pushing mechanism may be configured for pushing against a reservoir of the transdermal drug delivery apparatus. The latching mechanism may include flexible arms extending between the opposite ends of the latching mechanism, and the latching mechanism may be configured so that the arms release the pushing mechanism in response to the opposite ends being forced toward one another.

  • Publication number: 20190160273
    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.
