Abstract:
A composition including a solution suitable for introduction into a blood vessel comprising particles comprising a treatment agent and a polymeric product of at least one activated diamine and at least one activated dicarboxylic acid. A method including introducing a delivery device into a blood vessel; and introducing a solution into the blood vessel, the solution comprising particles comprising a treatment agent and a polymeric product of at least one activated diamine and at least one activated dicarboxylic acid, wherein the activated diamine comprises a product of a diol and an amino acid. A method including combining a treatment agent and a polymeric product of at least one activated diamine and at least one activated dicarboxylic acid; and forming particles of the combination suitable for delivery through a blood vessel.
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.
Abstract:
This invention relates to photodynamic therapy (PDT), more specifically PDT for atherosclerotic plaque via delivering PDT-loaded nanoparticles such as liposomes, polymersomes, micelles and polymeric nanoparticles into the diseased vascular tissue. This invention provides method and formulations for delivering multiple drugs and delivering drugs to specific targeted site.
