  • Patent number: 10300260
    Abstract: An applicator and method for applying a microneedle device to skin. The applicator can include a microneedle device and a housing configured to house the microneedle device. The housing can have a first surface configured to be positioned toward the skin. The applicator can include (i) an unactuated state in which the microneedle device is located within the housing and does not extend beyond the first surface of the housing, and (ii) an actuated state in which at least a portion of the microneedle device extends beyond the first surface of the housing. The applicator can further include a locking mechanism configured to lock the applicator in the actuated state. The method can include positioning the first surface of the housing of the applicator adjacent the skin; actuating the applicator to cause the applicator to change to the actuated state; and locking the applicator in the actuated state.

  • Patent number: 6958154
    Abstract: The present invention provides novel “patch in a bottle” technology in which a fluid composition, e.g., an aerosol spray, is applied onto a surface as a fluid, but then dries to form a covering element, such as a patch, having a tack free outer surface covering an underlying adhesive that helps adhere the patch to the substrate. The fluid compositions have a unique chemical formulation that allows such composite patches to form in situ. Specifically, the fluid compositions include a tacky component, such as an adhesive, and a film-forming, non-tacky component. The non-tacky and tacky components are selected to be immiscible with each other so that the components undergo phase separation as the fluid composition dries.

  • Patent number: 6113008
    Abstract: Actuator system is used to dispense a defined volume of a formulation from a pressurized vial. The system houses the vial in a receptacle of a base section that also includes a dispensing section (e.g., a funnel) through which the formulation is sprayed. The system includes a sleeve that fits over at least the vial and that can be pumped by the user to controllably spray the formulation from the vial onto the host animal. For instance, in a preferred mode of operation, the user places the system onto the host at the desired treatment site and then pushes or pulls down on the sleeve. This actuates a valve mechanism on the vial to spray an amount of the formulation through the dispensing section onto the host.
