Wax-based compositions, articles made therefrom, and methods of manufacture and use

Oral treatment devices formed from wax-based compositions that are thermally stable when formed into a three-dimensional shape to a temperature of at least 45° C. and plastically deformable at room temperature (25° C.). The wax-based compositions include a wax fraction homogeneously blended with a polymer fraction. The wax fraction includes at least one wax. The polymer fraction includes at least one polymer selected such that, when the wax and polymer are homogeneously blended together, they yield a wax-based composition having the desired properties of thermal stability and plastic deformability. Oral treatment devices are dimensionally stable to a temperature of at least 40° C. without external support and can be plastically deformed in a user's mouth to become at least partially customized to the size and shape of user's unique dentition and/or an appliance in a user's mouth.

End-capped polyisobutylene polyurethane

A polymeric material includes a polyisobutylene-polyurethane block copolymer. The polyisobutylene-polyurethane block copolymer includes soft segments, hard segments, and end groups. The soft segments include a polyisobutylene diol residue. The hard segments include a diisocyanate residue. The end groups are bonded by urea bonds to a portion of the diisocyanate residue.

Layer by layer coated mesh for local release of bio-active proteins

The present invention relates to biomaterials coated with an active agent eluting coating, wherein implantation of the coated biomaterial results in reduced implant-related complications and/or improved integration of the biomaterial into the host tissue and further relates to kits containing the coated biomaterial. The present invention also relates to methods and kits for coating the biomaterial. It is based, at least in part, on the discovery that biomaterial coated with a cytokine eluting coating resulted in the shift of early stage macrophage polarization that were associated with positive long-term effects such as minimized capsule formation and improved tissue quality and composition as compared to uncoated biomaterials.
