1. A system for stimulating healing of tissue at a tissue site, comprising:
a dressing configured to be positioned at the tissue site;
a source of therapeutic fluid;
a first heat exchange chamber having a fluid inlet fluidly coupled to the source of therapeutic fluid and a fluid outlet fluidly coupled to the dressing;
a second heat exchange chamber having a fluid inlet fluidly coupled to a second fluid source, the second fluid source being substantially the same as the source of therapeutic fluid and a fluid outlet configured to drain into the source of therapeutic fluid; and
a thermoelectric module thermally coupled with the first heat exchange chamber and the second heat exchange chamber, the thermoelectric module adapted to transfer heat between the first heat exchange chamber and the second heat exchange chamber to provide therapeutic fluid from the source of therapeutic fluid alternating between a first temperature and a second temperature.
