Abstract

A polymeric coating for medical devices. The polymeric coating may be formed by dissolving polymer solids in a liquid solvent and mixing the solids and liquid solvent together to form a homogeneous polymeric solution. The polymeric solution may be applied to at least a portion of a medical device and allowed to cure or dry to form a polymeric jacket or coating on the medical device. Alternatively, the polymeric solution may be cured or dried separately and then applied to the medical device. Various polymers may be utilized, including but not limited to polyurethane and/or polycarbonate based biopolymers. Various solvents may be utilized, including but not limited to dimethylacetamide.
