  • Patent number: 10307515
    Abstract: Systems and methods related to polymer foams are generally described. Some embodiments relate to compositions and methods for the preparation of polymer foams, and methods for using the polymer foams. The polymer foams can be applied to a body cavity and placed in contact with, for example, tissue, injured tissue, internal organs, etc. In some embodiments, the polymer foams can be formed within a body cavity (i.e., in situ foam formation). In addition, the foamed polymers may be capable of exerting a pressure on an internal surface of a body cavity and preventing or limiting movement of a bodily fluid (e.g., blood, etc.).

  • Patent number: 10251766
    Abstract: Apparatus and methods are provided for treating lesions within a blood vessel include a two-layer angioplasty balloon designed for the simultaneous deployment of multiple balloon-expanded stents. The high-compliance (elastic) outer balloon secures stent position. The low-compliance (inelastic) inner balloon drives angioplasty and stent expansion. Stent deployment starts with the injection of a small quantity of fluid into the outer balloon, which bulges slightly at both ends and into the spaces between the stents and, once the stent has expanded a little, between the struts of the stents. The injection port to the outer balloon is then closed, and fluid is injected only into the inner balloon, which expands, opening the stents.
