The invention discloses an insertable medical device for delivering one or more pro-healing agents to a site of deployment of a stent in a blood vessel. The surface of the insertable medical device is coated with nano-carriers that include the one or more pro-healing agents encapsulated with one or more biological agents. The nano-carriers are released when the insertable medical device is expanded at the site. The nano-carriers thus released penetrate tissues at the site resulting in dissolution of the one or more biological agents. Thereafter, the one or more pro-healing agents are released from the nano-carriers at the site. .Thus, an in-tissue release of the one or more pro-healing agents at the site is achieved thereby improving endothealisation, extracellular matrix formation and healing at the site post deployment of the stent in the blood vessel.
