A system for inducing desirable temperature effects on body tissue, the body tissue being disposed about a lumen. The system includes an elongate catheter having a proximal end and a distal end with an axis therebetween with an energy delivery portion for transmission of energy. A tissue analyzer configured to characterize the body tissue in the lumen proximate the energy delivery portion and an energy source coupled to the energy delivery portion transmitting tissue treatment energy, wherein the energy is non-RF energy. A processor coupled to the tissue analyzer and energy source, the processor configured to determine an appropriate treatment energy for the characterized body tissue so as to mildly heat the body tissue with the energy delivery portion without ablating.

La présente invention concerne un système d'induction d'effets thermiques souhaitables sur un tissu corporel, ledit tissu corporel étant disposé autour d'une lumière de l'organisme. Ce système comprend un cathéter allongé comportant une extrémité proximale et une extrémité distale entre lesquelles s'étend un axe, ainsi qu'une partie administrant de l'énergie capable d'assurer le transport d'énergie. L'invention concerne également un analyseur tissulaire conçu pour caractériser le tissu corporel dans la lumière à proximité de la partie administrant l'énergie, ainsi qu'une source d'énergie associée à la partie administrant l'énergie qui transporte l'énergie jusqu'au tissu, ladite énergie étant une énergie autre que radiofréquence. L'invention concerne également un processeur associé à l'analyseur tissulaire et à la source d'énergie, ledit processeur étant conçu pour déterminer une énergie de traitement adaptée au tissu corporel caractérisé, de manière à provoquer un léger chauffage dudit tissu corporel par la partie administrant l'énergie, sans ablation.
