  • Patent number: 8734825
    Abstract: A method and device for local delivery of a water-insoluble therapeutic agent to the tissue of a normal or diseased body lumen is disclosed. An expandable structure of a medical disposable device, such as a balloon of a balloon catheter, is coated with a non-durable coating which comprises poly(HEMA) complexed with iodine and has a substantially water-insoluble therapeutic agent dispersed therein. The medical disposable device is inserted into a body lumen, and expanded to contact the non-durable coating against the body lumen and deliver the substantially water-insoluble therapeutic agent to the body lumen tissue.

  • Patent number: 8673332
    Abstract: A method and device for local delivery of water-soluble or water-insoluble therapeutic agents to the surface of a normal or diseased body lumen is disclosed. An expandable structure of a medical disposable device, such as a balloon of a balloon catheter, is coated with an amphiphilic polymer coating comprising a therapeutic agent and an amphiphilic polymer or co-polymer.

  • Patent number: 8518105
    Abstract: A method and apparatus to treat regions of a vessel is described. A protein elastin-based polymer is released from the apparatus to coat the vessel lining as a primary therapy or an adjunct therapy with the delivery and deployment of a stent with or without drug coating. The protein elastin-based polymer may include a triblock structure having an elastin pentapeptide as the flanking block and a hydrophilic variant of the pentapeptide as the middle block. Both the flanking and middle blocks can be modified to change the structural and chemical properties of the polymer. In particular, the protein elastin based polymer is adapted to perform at least one of controlling release of a treatment agent, stimulating endothelial cell growth and stabilizing the vulnerable plaque to prevent rupture of the vulnerable plaque.
