(57) Abstract :
The present invention relates to a medical device carrying a nano coating by utilizing the same on the coronary stent systems and a
process for preparation thereof. The inventive coronary stents can be provided with various advantages/properties and properties
thereof. The material coated is a biocompatible bio-formulation which by means of a physical vapor deposition route ensures a very
thin coating (5 to 40 nm). In-vitro studies on human blood suggest that, the nano coated stent is devoid of platelet adhesion. Such a
hydrophobic nano coated stent surface reduces the chances of thrombosis as a result it provides a viable alternative to drug eluting
stents.
