1. A medical device comprising:
a medical device that is capable of being compacted and expanded; a polymeric substrate material, wherein said polymeric substrate material is fluoropolymeric in composition; a polymeric covering material attached to at least a portion of a surface of said substrate material; a first plurality of heparin molecules having anti-thrombin III binding activity end point attached to at least a portion of said polymeric covering material; and a composition comprising a second plurality of heparin molecules non-covalently combined with said first plurality of heparin molecules;
wherein said first plurality of heparin molecules have an anti-thrombin III binding activity of at least 10 picomoles anti-thrombin III per square centimeter (pmol/cm2) substrate material when measured following compaction of said medical device to 50% of said medical device's original size and expansion of said medical device. |
