A system for forming a medical implant to limit movement of a bodily fluid, comprising:

• a first chamber containing a first composition, the first composition including a polyol comprising up to 50 weight percent polyethylene oxide, up to 10 pphp of an amine catalyst, and up to 20 pphp water;
• a second chamber containing a second composition, the second composition including a multifunctional isocyanate;
• a mechanism that places the first composition into contact with the second composition thereby forming a polyurethane foam;
• and
• a nozzle insertable into a body of a patient, the nozzle configured to permit the flow of a mixture of the first and second compositions into a body cavity of the patient;
• wherein said foam is configured to control movement of bodily fluids when formed while in contact with bodily tissue;
• wherein the foam is characterized by a rise time of up to 150 seconds.
