  • Patent number: 8632848
    Abstract: A surface coating method for an orthodontic corrective bracket is provided, in which each orthodontic bracket formed of ceramic is covered with a titanium coating layer having a predetermined thickness so as to be able to minimize a frictional force and to increase surface hardness and durability while a wire fitted into slots of the brackets applies orthodontic tension to teeth. Accordingly, when the teeth are corrected using the ceramic orthodontic brackets on whose surfaces the titanium coating layer having a predetermined thickness is formed, the frictional force can be minimized while the wire fitted into the slots of the brackets is applying the orthodontic tension to the teeth, and thus it is possible to realize a tooth movement path desired by an orthodontist and to shorten a treatment period.

  • Patent number: 8632840
    Abstract: A method of making a compression device having a pressure applicator for applying a compression to a wearer's body part when the device is placed on the wearer's body includes applying a colorant having a first color to at least a portion of a loop material having a second color that is different than the first color. The step of applying colorant includes applying colorant to loops of the loop material so that repeated connection and disconnection of hook material attached to the device with the loop material causes loops having the first color of the colorant thereon to break so that the second color of the loop material is revealed by breakage of loops of the loop material having the colorant applied thereto.

  • Patent number: 8402629
    Abstract: Provided is a method of manufacturing a hollow microneedle structure. The method includes coating a hollow core having a predetermined section and being long in a lengthwise direction with a coating solution, and solidifying the coating solution to form a coating layer, depositing a metal seed layer on the coating layer, plating the seed metal layer with a metal to form a plated layer, cutting the hollow core having the plated layer at an inclination angle with respect to the lengthwise direction for form a surface inclination, and removing the hollow core and the coating layer to form a hollow microneedle structure. Thus, the hollow microneedle structure can be manufactured to have such diameter, length, hardness, and inclination angle as to minimize pain. By use of the hollow core, the microneedle structure can have vertical microneedles with a uniform inner diameter.

  • Patent number: 8389043
    Abstract: The invention relates to a preparation for restenosis prevention. The preparations for restenosis prevention known as yet do not reach sufficient active agent concentrations in the affected sections of the vascular walls as higher doses cause undesirable side effects. The present invention is a preparation to which at least one antihyperplastic agent is added that has a distribution ratio between butanol and water .gtoreq.0.5. The lipophilic active agent is absorbed by the vascular wall fast and in sufficient quantity. The preparation may be a liquid that can pass through capillaries and may contain a contrast agent so that the active agent is transferred into the vascular wall without any additional effort while the usually required contrast radiograms are taken. The preparation may also be applied to a catheter.

  • Patent number: 8367149
    Abstract: A method of coating a stent may comprise applying a composition including a drug and a polymer to the stent to form a coating. The release rate of the drug from the coating gradually increases along a length of the stent which extends axially from opposite ends of the stent. The variable drug release rate can be accomplished by varying the coating thickness, by applying a barrier region over the drug-containing composition, and/or by having different polymers in the coating, the polymers having different drug permeabilities.
