A catheter system for controlling the body temperature of a patient by modifying the temperature of blood flowing within a blood vessel of the patient. The catheter system comprises a catheter body (10) having a heat exchange region (22) in contact with the blood; and a mechanism for moving the heat exchange surface (21), thereby increasing heat exchange between the heat exchange surface and blood flowing past the exchange surface (21). Various methods of moving the heat exchange surface (21) are disclosed.
L'invention concerne un système de cathéter permettant de contrôler la température du corps d'un patient en modifiant la température du sang passant dans un vaisseau sanguin du patient. Le système de cathéter se compose d'un corps (10) de cathéter doté d'une zone (22) d'échange thermique en contact avec le sang et d'un mécanisme de déplacement de la surface (21) d'échange thermique, augmentant ainsi l'échange thermique entre la surface d'échange thermique et le sang passant par la surface (21) d'échange thermique. L'invention concerne également divers procédés de déplacement de la surface (21) d'échange thermique.
