    • Systems and methods related to polymer foams for the treatment of blood vessel dissections 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 or within a dissection caused by an intimal tear in a blood vessel, sealing the dissection and preventing further perfusion thereof. In some embodiments, the polymer foam can be formed within a body cavity (i.e., in-situ foam formation). The foam may be used to fill the dissection as a thrombosing agent. In addition, the foam may be used in conjunction with medical devices such as stents, stent-grafts, balloons, and catheters.
    • 通常描述与聚合物泡沫相关的用于治疗血管解剖的系统和方法。 一些实施方案涉及用于制备聚合物泡沫的组合物和方法,以及使用聚合物泡沫体的方法。 聚合物泡沫可以施加到由血管内膜撕裂引起的解剖内或在其中,密封解剖并防止其进一步灌注。 在一些实施例中,聚合物泡沫可以在体腔内形成(即原位泡沫形成)。 泡沫可用于填充解剖作为血栓形成剂。 此外,泡沫可以与诸如支架,支架移植物,气囊和导管的医疗装置结合使用。
