plural heat exchange fluid inlet holes in the
catheter body and forming respective passageways for heat
exchange fluid to flow from an inlet lumen into the
enclosure-forming structure;
at least one outlet hole in the body and forming a
fluid passageway from the enclosure-forming structure into
the catheter, the outlet hole leading to an outlet lumen
separate from the inlet lumen; and
a heat exchanger supplying heat exchange fluid to the
catheter and receiving heat exchange fluid from the catheter
in a closed circuit wherein the heat exchange fluid includes
at least one substance having a freezing point below zero
degrees Celsius (0C) and water.
13. A system for effecting heat exchange with a patient,
comprising:
a heat exchange catheter configured for placement in
a blood vessel of the patient without blocking the vessel to
induce hypothermia in the patient when heat exchange fluid
is circulated through the catheter, the catheter including:
a catheter body;
at least one enclosure-forming structure on the body;
plural heat exchange fluid inlet holes in the
catheter body and forming respective passageways for heat
exchange fluid into the enclosure-forming structure; and
at least one outlet hole in the body and forming a
fluid passageway from the enclosure-forming structure into
the catheter, wherein the inlet holes are smaller than the
