摘要： A method of preparing phakic intraocular lenses from hydrophobic materials is described. In this process, the lens is tested to determine whether it can float submerged in an aqueous medium. If it cannot (e.g., if it remains on top of the aqueous medium), the lens is surface treated (for example, by vacuum UV or corona discharge processes) to increase its wetting ability (e.g., to reduce it hydrophobicity). The lenses prepared by this process are also described.

摘要： A method for modifying the surface properties of tissue in vivo is described. The method comprises forming a liquid crystalline matrix on the tissue surface wherein the matrix comprises a tissue surface component. In one embodiment there is provided a method for improving the bonding of surgical glues and cements to cartilage and other synovial fluid wetted tissue surfaces. Such surfaces are contacted with a composition comprising a poly(hydroxy substituted amino acid) to form a liquid crystalline matrix on the tissue surface. The matrix is readily removed to provide a tissue surface that exibits improved bonding with surgical glues.

摘要： The present invention provides a method for coating a titanium based component with diamond-like carbon to reduce the thrombogeneticity of the component. In a preferred embodiment, the titanium based component is a heart valve. According to the present invention, the component is placed in a vacuum chamber and heated to about 600 DEG -650 DEG C. (1112 DEG -1202 DEG F.). Thereafter, silicon is then deposited onto the component, and the component is simultaneously bombarded with a beam of energetic ions to form a metal-silicide bonding layer. The component then is cooled to at least about 100 DEG C. (212 DEG F.), preferably about 80 DEG C. (176 DEG F.), and a diamond-like carbon precursor is condensed onto the metal-silicide bonding layer. The precursor is simultaneously bombarded with a beam of energetic ions to form a coating of diamond-like carbon.

摘要： A product (108) such as a medical device is manufactured using a superelastic material. A computer simulates performance of the object using predefined mathematical models. An object model describes the geometry of the object in a form suitable for numerical analysis. The object is made of only one (superelastic) material, but the numerical analysis is performed using the object model together with two different material models. The object model is partitioned such that a first material model (MT) is used to simulate the material behaviour for elements subject to superelastic tension and a second material model (MC) is used to simulate the material behaviour in parts of the object subject to superelastic compression. Compared with known models, the partitioned model is more accurate over the range of tensile and compressive conditions. The model can be used in an iterative design process to achieve a product meeting desired performance specifications.
