More Information
Summary:Embodiments of the invention provide optimized sputtered metallic surfaces adapted for use with implantable medical devices as well as methods for making and using such polymeric surfaces. These sputtered metallic surfaces have features that function to inhibit or avoid an inflammatory immune response generated by implantable medical devices. Typical embodiments of the invention include an implantable glucose sensor used in the management of diabetes having a sputtered metallic surface adapted to contact an in vivo environment.
