Abstract: According to an aspect of the present invention, implantable or insertable blood-contacting devices are provided, which contain one or more release regions that release nitric oxide and one or more anti-restenotic agents. The release region contains one or more polymeric components. The release region also optionally contains one or more inorganic components. Nitric oxide producing groups may be attached to the polymeric component(s), to the optional inorganic component(s), or both. The one or more anti-restenotic agents may be admixed with the polymeric and optional inorganic components, attached to the polymeric component(s), attached to the optional inorganic component(s), or a combination thereof.

Abstract: A photochromic [1,2-b] naphthopyran having a fluoro substituent in at least one of the 7-position or the 9-position of the naphthopyran provides a stable photochromic compound with a narrow range of absorption. A preferred photochromic naphthopyran has the 2-position of the naphthopyran with two aromatic substituents thereon. It is further preferred to have at least one 2-position aromatic substituent comprising a phenyl group.

Abstract: Benzodioxino-naphtho[1,2-b]pyran compounds having particularly advantageous photochromic properties, such as, high sensitivity/coloration, two distinct absorption bands in the 430-500 nm range and 520-620 nm range of the visible spectrum may be generally described as a naphthopyran having a central nucleus of the formula: wherein F is a 1,4-benzodioxine ring with its 2,3 positions fused to the i, j, or k faces; and R1 and R2 are the atoms or groups providing photochromic properties to the naphthopyran.

Abstract: The present invention relates to naphthopyrans, particularly 3,3-[substituted]-naphtho[2,1-b]pyrans and 2,2-[substituted]-naphtho[1,2-b]pyrans and particularly to novel substitution on the 3-position and 2-position, respectively, of these naphthopyrans. It has been found that there are classes and types of substitution on the 3-position and 2-position (especially combinations of 3,3-substitution and 2,2-substitution) which are novel. Some of these substitutions provide particularly desirable properties.
