  • Patent number: 9351902
    Abstract: A device for scar management includes an applicator head including a recess having a rotating means therein, a reservoir containing a silicone composition fluidly connected to the applicator head, and a metering valve fluidly connected to the reservoir. The composition has viscosity of 3,000 to 8,000 cps, and consists of a mixture of cyclopentasiloxane, dimethiconol, dimethicone, and dimethicone/vinyl dimethicone crosspolymer. A metered dose of the silicone composition is delivered from the reservoir to the applicator head upon the application of external pressure to the metering valve. The invention also relates to a method for scar management using such device by identifying a target skin area having a wound or scar, contacting the outward surface of the applicator head to the target skin area, massaging the rotating means of the applicator head on the target skin area, and applying the silicone composition to the target skin area via the rotating means.

  • Patent number: 7850995
    Abstract: Bioadhesive nanoparticulate compositions, comprising active agent particles and one or more cationic surface stabilizers, are described. The cationic surface stabilizers prevent aggregation of the nanoparticles and increase bioadhesion of the nanoparticles to biological substrates, such as an insect, teeth, bone, nails, chitin, feathers, scales, mucous, skin, hair, plant tissue, etc. The particles may consist of pharmacologically active compounds (e.g., drug compounds for human or veterinary use), agricultural chemicals (pesticides, herbicides, fertilizers, and the like), cosmetic agents, consumer products (coloring agents, flavors, or fragrances), or other materials which function by interacting with biological substrates. In addition, the invention relates to methods of preparing and using such bioadhesive nanoparticulate compositions.
