Methods, computer programming and devices for transferring heat to and/or from a body portion of a mammal are provided. One approach includes directly determining a state of vasoconstriction or vasodilation in a portion of a body, and supplying heat to the portion of the body when vasoconstriction is determined, and removing heat from the portion of the body when vasodilation is determined. The body portion preferably includes specific heat exchange vasculature. In another approach, a transition of the body portion from a state of vasodilation to vasoconstriction is determined and the body portion is then actively kept in a state of vasodilation while removing heat therefrom.

La présente invention a trait à des procédés, une programmation informatique et des dispositifs pour le transfert thermique depuis et/ou vers une portion de corps d'un mammifère. Une technique comprend la détermination directe de l'état de vasoconstriction ou de vasodilatation dans la portion d'un corps, et la fourniture de la chaleur à la portion du corps lors de la détermination de vasoconstriction, et le retrait de la chaleur de la portion du corps lors de la détermination de vasodilatation. La portion de corps comporte, de préférence, un système vasculaire d'échange de chaleur spécifique. Dans une autre technique, on détermine une transition de la portion de corps d'un état de vasodilatation à un état de vasoconstriction tout en effectuant la retrait de la chaleur de celle-ci.
