  • Patent number: 8802184
    Abstract: A method of modifying a medical device such as a stent with nano-constructs is disclosed. The method comprises applying a first fluid to the stent; immersing the stent being wet from the first fluid into a second fluid having a suspension of nano-constructs; and removing the stent from the second fluid and allowing the first and second fluid to be removed such that the nano-constructs are carried by the stent for in vivo application of the constructs to a target location of a mammalian subject. The nano-constructs can be attached to the surface of the stent, can be attached to a surface of the coating of the stent, can be embedded into the stent, or can be embedded into the coating.

  • Patent number: 8735344
    Abstract: A method including advancing a delivery device through a lumen of a blood vessel to a particular region in the blood vessel; and introducing a composition including a sustained-release carrier and an apolipoprotein A-I (Apo A-I) synthetic mimetic peptide into a wall of the blood vessel at the particular region, wherein the peptide has a property that renders the peptide effective in reverse cholesterol transport. A composition including an apolipoprotein A-I (Apo A-I) synthetic peptide, or combination of an Apo A-I synthetic mimetic peptide and an Acyl CoA cholesterol: acyltransferase (ACAT) inhibitor in a form suitable for delivery into a blood vessel, the peptide including an amino acid sequence in an order reverse to an order of various Apo A-I mimetic peptides, or endogenous Apo A-I analogs, or a chimera of helix 1 and helix 9 of endogenous Apo A-I.
