Abstract: A composition for use with healthcare products such as medical device includes one or more biologically-active agents for release into bodily fluids. The composition can be applied to a substrate to form an erodible layer and a polymer layer. Biologically-active agent(s) are releasable from the erodible layer and the polymer layer when exposed to aqueous fluids.
Abstract: An antithrombotic composition includes a hydrophilic polymer backbone and an antithrombotic moiety covalently linked to the hydrophilic polymer backbone. The antithrombotic composition is formed by exposing a hydrophilic polymer including a hydroxyl group to an antithrombotic polysaccharide without having to first aminate the hydrophilic polymer.
