The present invention provides a medical device having an elongate body with both a proximal end and a distal end, wherein the elongate body defines an intake lumen and an exhaust lumen. The medical device also has a first pliable element defining a cooling chamber disposed at a point along the elongate body, with the cooling chamber being in fluid communication with the intake lumen and the exhaust lumen. A second pliable element is provided which at least partially encloses the first pliable element, thereby defining a junction between the first and second pliable element. Moreover, a check valve is included which is in fluid communication with the junction between the first pliable element and second pliable element, the valve further being in fluid communication with the exhaust lumen. In addition, the medical device may include sensors or other monitoring means in fluid communication with the junction and the cooling chamber.

L'invention concerne un dispositif médical présentant un corps allongé ayant une extrémité proximale et une extrémité distale, le corps allongé définissant une lumière d'entrée et une lumière de sortie. Le dispositif médical présente également un premier élément pliable définissant une chambre de refroidissement disposée en un point du corps allongé, ladite chambre de refroidissement étant en communication de fluide avec la lumière d'entrée et la lumière de sortie. Il est prévu un second élément pliable qui entoure au moins partiellement le premier élément pliable, définissant ainsi une jonction entre le premier et le second élément pliable. Il est en outre prévu un clapet de non-retour qui est en communication de fluide avec la jonction entre le premier élément pliable et le second élément pliable, ledit clapet étant par ailleurs en communication de fluide avec la lumière de sortie. De plus, le dispositif médical peut comprendre des détecteurs ou d'autres moyens de contrôle, en communication de fluide avec la jonction et la chambre de refroidissement.
