  • Publication number: 20120277727
    Abstract: 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.

  • Publication number: 20120277726
    Abstract: A method for delivering at least one drug at a target site in a blood vessel for treating at least one of an acute myocardial infarction, a thrombus containing lesion and a saphenous-vein graft lesion is disclosed. The method includes delivering nano-carriers at the target site. The nano-carriers include one or more drugs encapsulated with a first biological agent. The nano-carriers further include a second biological agent in contact with one or more of the first biological agent and the one or more drugs. The first biological agent and the second biological agent have a first dissolution rate and a second dissolution rate respectively. The first dissolution rate is different from the second dissolution rate. The one or more drugs are released at the target site from the nano-carriers at a first release rate and a second release rate in response to dissolution of the first biological agent and the second biological agent, respectively.

  • Publication number: 20120276280
    Abstract: A coating system for coating an Insertable Medical Device (IMD) with one or more drugs is disclosed. The coating system includes a spray nozzle unit for coating the IMD with one or more drugs. The IMD includes a guiding member, a coating member and a supporting member. The IMD is passed through a protection tube such that the guiding member is located within the protection tube and an end of the supporting member is connected to a holder to expose the coating member of the IMD to the spray nozzle unit. The protection tube is received by a mandrel fixture which includes a circular disc for holding and rotating the protection tube and the IMD within the protection tube. When the protection tube along with the IMD is rotated, the spray nozzle unit coats the coating member of the IMD with the one or more drugs.

  • Publication number: 20120065584
    Abstract: A drug-delivering medical device for delivering a drug to a target site in a body lumen is disclosed. The drug-delivering medical device includes a balloon catheter and an inflatable balloon positioned on the balloon catheter. The inflatable balloon has a hydrophilic surface. One or more portions of the hydrophilic surface are coated with two or more nano-carriers. A nano-carrier of the two or more nano-carriers includes a drug surrounded by an encapsulating medium. As the drug is surrounded by the encapsulating medium, the surface of the nano-carrier is devoid of the drug. When the inflatable balloon is inflated upon coming in proximity to a target site in the body lumen, about 30% to 80% of the two or more nano-carriers are released from the hydrophilic surface within 15-90 seconds.

  • Publication number: 20110264188
    Abstract: A drug-delivering insertable medical device for treating a medical condition associated with a body lumen is disclosed. The drug-delivering insertable medical device includes an outer surface coated with two or more nano-carriers having two or more average diameters. A nano-carrier of the two or more nano-carriers has an average diameter suitable for penetrating one or more layers of two or more layers of the body lumen. The nano-carrier includes a drug surrounded by an encapsulating medium. The encapsulating medium includes one or more of a biological agent, a blood excipient, and a phospholipid.
