The image of a predetermined treatment area of the user's skin is first captured by an imaging device. The captured image data is then analyzed by a computing device to generate a unique skin profile for the user, which is indicative of the skin conditions at the predetermined treatment area. Based on such skin profile, a printing device prints out one or more cosmetic delivery sheets that can be applied to the predetermined treatment area. Each of the cosmetic delivery sheets contains a substrate with multiple isolate, discrete regions, while at least two of the regions are imprinted with different skin benefit agents for treating different skin conditions of the predetermined treatment area according to the unique skin profile of the user.

    Abstract: A method of manufacturing a sturdy and pliable fibrous hemostatic dressing by making fibers that maximally expose surface area per unit weight of active ingredients as a means for aiding in the clot forming process and as a means of minimizing waste of active ingredients. The method uses a rotating object to spin off a liquid biocompatible fiber precursor, which is added at its center. Fibers formed then deposit on a collector located at a distance from the rotating object creating a fiber layer on the collector. An electrical potential difference is maintained between the rotating disk and the collector. Then, a liquid procoagulation species is introduced at the center of the rotating disk such that it spins off the rotating disk and coats the fibers.

  • Patent number: 7537795
    Abstract: A device (12) and method are provided for percutaneous transdermal delivery of a potent pharmacologically active agent. The agent is dissolved in water to form an aqueous coating solution having an appropriate viscosity for coating extremely tiny skin piercing elements (10). The coating solution is applied to the skin piercing elements (10) using known coating techniques and then dried. The device (12) is applied to the skin of a living animal (e.g., a human), causing the microprotrusions (10) to pierce the stratum corneum and deliver a therapeutically effect dose of the agent to the animal.

  • Publication number: 20090123515
    Abstract: A method for depositing a coating comprising a polymer and pharmaceutical agent on a substrate, comprising the following steps: discharging at least one pharmaceutical agent in a therapeutically desirable morphology in dry powder form through a first orifice; discharging at least one polymer in dry powder form through a second orifice; depositing the polymer and/or pharmaceutical particles onto said substrate, wherein an electrical potential is maintained between the substrate and the pharmaceutical and/or polymer particles, thereby forming said coating; and sintering said coating under conditions that do not substantially modify the morphology of said pharmaceutical agent.

  • Publication number: 20090117158
    Abstract: Provided herein are microprojections and microprojection arrays wherein a microprojection is coated with at least two layers. One layer comprises a biologically active agent, for example, a PTH agent and optionally other excipients. Another layer, which is generally, initially devoid of active agent comprises a polymer or a mix of polymers to provide controlled release, for example sustained release, of the biologically active agent contained in the first layer. Microprojections coated with multiple layers, some layers containing a biologically active agent and other layers containing a polymer for controlled release are also contemplated herein.

  • Publication number: 20090076430
    Abstract: A bandage that includes a material, which can be breathable, having a first surface, and a plurality of superhydrophobic particles attached to the first surface. The plurality of superhydrophobic particles ranging in size from about 100 nanometers to about 10 micrometers. The superhydrophobic particles including a protrusive material defining a plurality of nanopores and a plurality of spaced apart nanostructures that define an external boundary of the hydrophobic particles. The nanopores providing a flow through porosity. The first surface can be rendered superhydrophobic by the attached superhydrophobic particles. The material can have a second surface opposite the first surface that is hydrophilic. The superhydrophobic particles can be adhered to the first surface by a binder. Also included is a method of making the bandages described herein.
