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 gaseous inflation medium can be introduced from an external gas source through the inflation lumen to inflate the first balloon, so as to apply a substantially even pressure along a substantial portion of an inner surface of a uterine cavity to reduce or eliminate bleeding along such inner surface. The second inflatable balloon functions to confine any gaseous inflation medium that escapes from the first balloon, due to leakage or rapture of such first balloon, and to discharge such escaped gaseous inflation medium through the deflation lumen.
