A novel method and system is disclosed to realistically simulate the progress or worsening of facial skin features that contribute to the overall look and condition of the skin. The method utilizes two close-up photographs of the face, one is captured with a digital camera in standard white light, and the other is captured with the same camera in UV light. Then, the method processes these images to simulate the progress or worsening of the major skin features: hyperpigmented spots, wrinkles and small texture features. The worsening of these features simulates facial skin aging due to prolonged exposures to sunlight, biological aging or degradation of the skin health. The progress of these features simulates the improvement of facial skin in terms of overall look and healthiness as though the patient has gone through a treatment. Therefore, the present invention discloses a series of methods that are useful in dermatology, cosmetics and computer animations.

This invention relates to cemented carbide articles that are characterized by substantially improved biocompatibility with human skin, tissue, organs, etc., compared with articles made from conventional cemented carbides. The essential feature of these improved biocompatible cemented carbide articles is a binder-depleted zone at and near the exposed surfaces of the articles. By depleting the binder (which mainly consists of Co and / or Ni, as well as their alloys) at and near the surface, the toxic effects of Co and Ni (known carcinogens), as well as the allergic reactions that these metals can cause when in contact with human skin, are eliminated. By depleting the binder only at and near the surface, the bulk properties of the cemented carbide article are not compromised or altered in any manner. Applications of these binder-depleted cemented carbides could include articles that human skin may experience prolonged exposure to, for example, jewelry articles such as rings, bracelets, bangles, chains, necklaces, pendants, watches, watch cases, watch straps, etc. In addition, the cemented carbides of this invention may be used in applications where the article comes directly in contact with human skin, tissue, organs, etc. such as surgical and other medical instruments, razor blades, etc. Also, other applications could include knives, tools, dies, and other wear components that are used to process and handle, and hence, come into direct contact with materials meant for human consumption and / or ingestion. Examples of such materials include foodstuffs and pharmaceuticals.

The present invention protects a catheter during shipment and storage. The device holds a portion of the catheter suspended such that the portion does not contact the device. When the suspended portion includes a stent treated with a therapeutic coating, the coating is protected from physical damage and from the risk that extended contact of the coating with packaging materials may result in the therapeutic agent migrating out of the coating and into the packaging materials or components of the packaging materials migrating into the therapeutic coating, both of which can occur if a therapeutic coating remains in contact with another material for an extended period of time. A catheter bearing an untreated stent, a balloon catheter, and other types of catheter would be similarly protected from physical or chemical damage.
