    摘要: Polymeric compositions have photochromic and blue-light filtering ability and are useful in the manufacture of ophthalmic medical devices. The polymeric compositions comprise a photochromic material incorporated into polymeric host materials and are activatable by blue light having a first wavelength range to become photochromic, and are thereby capable of absorbing blue light in a second wavelength range. Methods of making the compositions comprise incorporating a photochromic material into a polymeric host material.

    摘要: A drug delivery device for placement in the eye includes a drug core comprising a pharmaceutically active agent, and a holder that holds the drug core. The holder is made of a material impermeable to passage of the active agent and includes an opening for passage of the pharmaceutically agent therethrough to eye tissue. The device includes a layer of material permeable to passage of the active agent. The device further includes a disc of impermeable material disposed between the drug core and the opening in the holder.

    摘要: A star macromonomer comprises multiple side chains attached to a nucleus, each side chain having at least a segment comprising hydrophobic units and at least a segment comprising hydrophilic units. Polymeric materials having improved oxygen permeability and water and ion transport rates are produced by polymerizing compositions comprising such a star macromonomer. Such polymeric materials are desirable for producing medical devices, such as ophthalmic devices.

    摘要: The present invention relates to polymeric compositions useful in the manufacture of biocompatible medical devices. More particularly, the present invention relates to certain cationic monomers capable of polymerization to form polymeric compositions having desirable physical characteristics useful in the manufacture of ophthalmic devices. Such properties include the ability to extract the polymerized medical devices with water. This avoids the use of organic solvents as is typical in the art. The polymer compositions comprise polymerized silicon-containing monomers end-capped with polymerizable cationic hydrophilic groups.

    摘要: A surface-modified medical device comprises a hydrophilic coating that comprises units of a hydrophilic monomer and a coupling agent that has coupling functional groups, at least a portion of which is coupled to the surface functional groups of the medical device. A method for producing such a surface-modified medical device comprises forming the hydrophilic coating by coupling units of the hydrophilic monomer to the medical device through the coupling agent. Medical devices, such as stents, implants, catheters, and ophthalmic devices, are included.
