Title: Treatment methods utilizing inflatable dual balloon catheter

Abstract: A dual balloon catheter apparatus for controlling postpartum hemorrhage in uterine or vaginal cavities or hemorrhage in other body cavities, comprising: (1) a catheter having an inflation lumen and a deflation lumen; (2) a first inflatable balloon in fluid communication with the inflation lumen; and (3) a second inflatable balloon encompassing the first balloon and in fluid communication with the deflation lumen. A first fluid inflation medium can be introduced from an external fluid source through the inflation lumen to inflate the first balloon, so as to apply a substantially even pressure along a substantial portion of a uterine cavity to reduce or eliminate bleeding along such inner surface. The second inflatable balloon functions to confine any first fluid inflation medium that escapes (e.g., by leakage or rupture) from the first balloon, and to discharge such medium through the deflation lumen.
