Abstract: Disclosed are medical components, formulations for making medical components, methods of forming medical components, and methods of making medical devices from the medical components. The medical components possess radiopacity. In an embodiment, a medical component comprises from 5 to 50 wt % of a polyurethane and from 50 to 95 wt % of a radiopacifier, based on the total weight of the medical component, wherein the medical component has a thickness of from 0.025 to 1 mm.

Abstract: The present invention relates to a micelle composition comprising a hydrophobic compound and an amphiphilic block copolymer, wherein the amphiphilic block copolymer consists of a hydrophobic block A and a hydrophilic block B, the hydrophobic block A comprises at least one hydrophobic polymeric unit X and the hydrophilic block B comprises at least one hydrophilic polymeric unit Y whereby the X and Y blocks alternate. The present invention further relates to a process for the preparation of the micelle composition wherein the process comprises the steps of: a) dissolving the hydrophobic compound and the amphiphilic block copolymer in an organic solvent to form a solution, b) adding said organic solution into an aqueous medium, c) optionally repeating aforementioned steps.
