A system for treating uterine atony, and promoting contraction of a uterus includes a heat transference article having a chilled surface in contact with an inner or outer surface of the uterus for a length of time sufficient to promote contraction while avoiding tissue damage. A heat transference medium such as a chilled saline solution, or cold gel is introduced to the article by injection, pre-filling, immersion or other suitable means, and is circulating or non-circulating.
