The present invention provides methods, apparatus, and kits for detection and/or treatment of vulnerable plaque of a blood vessel having a lumen surface. Detection methods include sensing a temperature differential along a lumen surface with temperature sensors (78) that thermally couple to the lumen surface. Treatment methods include controlled and safe cryogenic cooling of vulnerable plaque to inhibit release of retained fluid within the vulnerable plaque so as to inhibit acute coronary syndrome and to help maintain patency of a body lumen. Treatment methods may include additional treatments, such as primary treatments of passivation.

La présente invention se rapporte à des procédés, un appareil et des trousses pour la détection et/ou le traitement de plaques d'athérosclérose vulnérables d'un vaisseau sanguin présentant une surface de lumière. Lesdits procédés de détection consistent à détecter un différentiel de température le long d'une surface de lumière au moyen de capteurs de température (78) qui sont thermiquement couplés à la surface de lumière. Les procédés de traitement incluent un refroidissement cryogénique régulé et sûr de la plaque vulnérable visant à inhiber la libération de fluide retenu au sein de ladite plaque et destiné à empêcher tout syndrome coronaire subit et à faciliter le maintien de la perméabilité d'une lumière corporelle. Lesdits procédés thérapeutiques peuvent inclure des traitements complémentaires tels que des traitements primaires ou une passivation.
