Patents by Inventor Derek D. Pham

Derek D. Pham has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9534088
    Abstract: A polymeric material with a variable modulus of elasticity is described herein. The polymeric material described herein is useful for forming implantable medical devices (e.g. ophthalmic lenses, breast implants, and body augmentation devices). In addition, medical devices formed from the polymer material can be used to controllably release a therapeutic agent. Also, the polymeric material may be used to prepare topical compositions or other applications or devices where control of a mechanical property such as material modulus is important.
    Type: Grant

  • Patent number: 8530590
    Abstract: Described herein are silicone fluids and silicone materials that posses high glass transition temperatures (Tgs) when compared to conventional silicone materials. In one embodiment, an increased Tg allows the formation of objects and materials by cryogenic lathing. The fluids and materials can be formed by curing silicone fluid with a cross-linker mixture comprising a cross-linker and a monofunctional hydride compound. Upon formation, the silicone materials can be extracted over long periods of time without loss of optical quality. The silicone materials can be sufficiently soft allowing folding and insertion through small incisions in the eye. Additionally, methods of forming optical silicone materials, lenses and silicone materials in general are also disclosed. In one embodiment, the method of forming a silicone based lens using cryogenic lathing techniques is described.
