Disclosed is a disposable closed fluid loop for providing heat and compression to an intraductal fluid aspiration device. A plurality of bladders are configured to receive a pressurized inflation fluid, and to inflate in response thereto. The fluid is further configured to flow adjacent a heat exchanger, thereby receiving thermal energy, which it imparts to the bladders through conduction. Accordingly, the disclosed fluid loop provides heated inflation media to inflate a plurality of bladders to provide heat and compression to an intraductal fluid aspiration patient.
