1. A system for forming a medical implant to limit movement of a bodily fluid, comprising:
- a first composition comprising, a polyol;
a second composition comprising, a multifunctional isocyanate, the second composition being physically separated from the first composition;
a mechanism that places the first composition into contact with the second composition, thereby forming an elastomeric polyurethane foam; and
a device insertable into a body of a patient, the device configured to permit the flow of a mixture of the first and second compositions into a body cavity of the patient, wherein said elastomeric polyurethane foam undergoes greater than 12 times expansion.

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.).
