Abstract: 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.

Abstract: Bioresorbable silk fibroin tracheal stents can be designed and engineered to maintain a tracheal opening. A tracheal stent will maintain a tracheal opening for a period while tissue structure and function is restored. Bioresorbable silk fibroin tracheal stents programmably degrade without negative biological or clinical outcomes. Bioresorbable silk fibroin tracheal stents do not need to be removed following tracheal restoration. Bioresorbable biopolymer tracheal stents can be internally or externally deployed. Bioresorbable biopolymer tracheal stents, for example can be internally or externally deployed in a patient. Such stents may be affixed to function as a splint with tunable mechanically properties to treat, for example, a patient with severe airway collapse.

Abstract: The present invention relates generally to systems and methods and systems for generating polymer foams within body cavities to locate and/or control bleeding. The present invention further relates to methods and systems for generating polymer foams within non-compressible wounds to control or stop bleeding. The present invention further relates to the use of foams and gels for medical and cosmetic purposes.

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 lung at or near an alveolar duct targeted for reduction, occluding the airway and leading to tissue necrosis because the foam prevents oxygenation of the tissue surrounding the duct. In some embodiments, the polymer foams can be formed within a body cavity (i.e., in-situ foam formation). In addition, the foam may form a seal, eliminating the source of air leaks.
