1. A system for removing heat from subcutaneous lipid-rich cells of a subject, the system comprising:

  • a plurality of spaced apart cooling elements, wherein the individual cooling elements are configured to contain a liquid coolant and include a heat exchanging surface and a sensing element;

    a flexible substrate including a first surface and a second surface, the flexible substrate carrying the cooling elements such that the cooling elements are movable relative to one another and the heat exchanging surfaces and the first surface of the substrate face a subject when the heat exchanging surfaces remove heat from subcutaneous tissue of the subject to affect subcutaneous lipid-rich cells of the subject;

    a cooling unit in fluid communication with the cooling elements, the cooling unit is configured to remove heat from the liquid coolant that has absorbed heat from the subcutaneous lipid-rich cells; and

    a processing unit in communication with the sensing element and programmed to individually control the cooling elements such that the cooling elements cool the subcutaneous lipid-rich cells of the subject to a sufficiently low temperature for at least 10 minutes so as to selectively disrupt the subcutaneous lipid-rich cells.
