Apparatus for adjusting temperature of body

A system for adjusting a temperature of a body comprising:

• a sheath (300) for providing a channel (301) from outside said body to a pleural cavity inside said body, said channel (301) being configured to allow passage of a non-intravenous heat exchange unit (220) for heating or cooling said pleural cavity;
• wherein said sheath comprises a guiding section (304) being angular to said channel (301)
• the non-intravenous heat exchange unit (220) comprising an inner fluid channel, an outer contour, a fluid inlet (221), and a fluid outlet (222), where at least a part of said inner fluid channel of said heat exchange unit (220) is adapted for passing liquid through said fluid inlet (221) into and through said inner fluid channel and from said inner fluid channel through said fluid outlet (222), and
• wherein said heat exchange unit is adapted to change shape, wherein a compressed shape is achieved where the outer contour of said heat exchange unit (220) is smaller than the inner diameter of said channel (301) of said sheath (300) and the inner diameter of said guiding section (304) of said sheath (300) and
• wherein the compressed shape is further achieved by the heat exchange unit being folded in a wave-like manner;
• and
• wherein said at least part of said inner fluid channel of said heat exchange unit is adapted for inserting through the channel (301) of said sheath (300) and into said pleural cavity inside a body in a compressed state, and where liquid entering the fluid inlet (221) and into the heat exchange unit (220) expands the inner fluid channel and eventually expands the heat exchange unit (220);
• and
• at least one elongated and rigid element running in a direction parallel to the fluid inlet and the fluid outlet adapted to at least partially withstand the compression of the heat exchange element on removal of fluid thus forcing the compression to be performed substantially perpendicular to the insertion direction.
