Publication number: 20110004150Abstract: A method for delivery of substance through at least one dermal layer, by providing a substance in microcapsules at a predetermined size, within a medium (150) for holding the microcapsules; placing the medium for holding the microcapsules on a surface of a patch (100) adjacent the skin (320) of a human or animal; and applying energy (200) to the patch, the energy having a characteristic of disturbing the integrity of the microcapsules, thereby resulting in release of the substance from the microcapsules. The energy may be selectively applied to release the substance at desired times. The substance may be a drug or other active agent.Type: ApplicationFiled: September 15, 2010Publication date: January 6, 2011Applicant: ULTRA-SONIC TECHNOLOGIES, L.L.C.Inventor: Ludwig J. Weimann

Patent number: 7862801Abstract: A dental bleaching composition comprises a dental bleaching agent and a polyvinylpyrrolidone thickening agent. The bleaching composition may include water, flavoring agents, a basic substance and desensitizing agents, as desired. Polyvinylpyrrolidone avoids acid etching and chelation of teeth that were problematic in bleaches using carbomer as a thickener. A delivery system for delivering the bleaching composition comprises the aforementioned dental bleaching composition in combination with a moisture-resistant barrier layer such as a dental tray or a flexible strip of material.Type: GrantFiled: June 17, 2004Date of Patent: January 4, 2011Assignee: Ultradent Products, Inc.Inventor: Tianming Chen

Patent number: 7862802Abstract: The present invention relates to a dry type tooth whitening patch comprising peroxide as a tooth whitening agent. In particular, disclosed is a dry type tooth whitening patch in which a peroxide is contained, as a teeth whitening agent, in a matrix type adhesive layer. The adhesive layer includes, as a base polymer thereof, a hydrophilic glass polymer which provides a strong adhesion to teeth while releasing the tooth whitening agent when hydrated on the enamel layers of teeth in the moist oral cavity. The dry type patch according to the present invention is convenient in use, as compared to wet type patches. Further, it exhibits a superior adhesion while being maintained in a state attached to the teeth for a lengthened period of time so as to assure an enough contact time between the whitening agent in the patch and stains on the teeth, thereby giving a sufficient whitening effect.Type: GrantFiled: August 10, 2004Date of Patent: January 4, 2011Assignee: LG Household & Health Care Ltd.Inventors: Ji-Young Kim, Jong-Ho Kim, Sug-Youn Chang, Sei-Young Yun

Patent number: 7825289Abstract: An apparatus for promoting the healing of a wound includes a pressure-sensitive adhesive disposed around a periphery of the wound, and a membrane layer in positioned over the wound with a lower surface in contact with the pressure-sensitive adhesive to form a substantially fluid-tight seal to define reservoir over the wound in which a negative pressure may be maintained. In fluid communication with the reservoir is a vacuum source suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound. A resilient member is placed over an upper surface of the membrane layer, and a compression member is configured to apply a compressive force to the resilient member. The resilient member distributes the compressive force to the membrane layer to reinforce the fluid tight-seal.Type: GrantFiled: May 16, 2008Date of Patent: November 2, 2010Assignee: Tyco Healthcare Group LPInventor: Mark A.
