Heat exchange catheter with discrete heat exchange elements

A catheter for heat exchange (24, 50, 100, 150, 180, 350) comprising: (i) a longitudinal catheter shaft (52, 104, 164, 182, 218, 240, 306, 358) with a proximal end and a distal end; (Ii) a heat exchange region (56, 42, 44, 106, 152, 210) comprising a plurality of heat exchange elements (58, 58 ', 102, 166, 184, 200, 206, 212, 220, 246, 302, 354), each of said heat exchange elements a length and opposed ends, each heat exchange element being connected by at least one of its ends to the catheter shaft; wherein at least a portion of the length of each heat exchange element is spaced transversely from the tubular shaft so that when inserted into a body cavity in which there is a fluid having a body fluid therein, the body fluid surrounds circumferentially each heat exchange element.
